The casualties of Mongolia’s doomed love affair with coal

All the rooms in the three-storey Songinokhairkhan hospital in western Ulaanbaatar, Mongolia’s capital city, are full. They are mostly occupied by small children being treated for respiratory problems, according to the busy nurses here.

The cause is heavy pollution, mainly from the country’s decades-long over-reliance on coal.

Children’s hospitals in the area are overburdened and paediatricians can only treat the symptoms of health problems caused by air pollution, they are unable to remove the cause.

A young mother, Ganchimeg, waits for the fever to let up in her one-year-old daughter’s trembling body. They have been here all day. “She’s been coughing a lot,” says the tired mother. “When we came here they told me it’s probably pneumonia.” Her daughter smiles, and then coughs.

UNICEF declared Mongolia’s air pollution problem a “child health crisis” in a 2018 report which stated: “In the last 10 years, incidences of respiratory diseases in Ulaanbaatar alarmingly increased including a 2.7-fold increase in respiratory infections per 10,000 population.

“Pneumonia is now the second leading cause for under-five child mortality in the country. Children living in a highly polluted district of central Ulaanbaatar were found to have 40 percent lower lung function than children living in a rural area.”

Ariunsanaa and Oyun (Mongolians tend only to use one name), are a young couple living in Ulaanbaatar’s western ger district. Gers are traditional Mongolian yurts – small wooden structures in which whole families live.

Both their children – a four-year-old son and a one-year-old daughter – have been hospitalised this winter with fever, coughing and, eventually, pneumonia. “Same old story every winter,” says Ariunsanaa, preparing suutei tsai and biscuits inside their ger while the TV shows flickering images of a conflict far away.

“It’s the same strain of the flu that returns every winter, and every year it takes its toll on the kids a lot worse than the previous winter.

“Medicines and antibiotics aren’t free, you know,” he adds.

Behind a curtain hangs Ariunsanaa’s shaman coat. Interest in Mongolian Shamanism has risen among the young, after being banned during Communist rule. Local people seek Ariunsanaa’s counsel on matters from relationships to health.

The price of success

This is not all that has changed here since the fall of Communism.

Democracy’s arrival in Mongolia in 1990, alongside an economic boom from the country’s rich coal resources, gave birth to a market-economy class system defined by stunning income inequality.

“Despite strong overall growth, job creation and poverty alleviation remains a significant challenge,” is how the International Monetary Fund summarised the situation in its 2019 member-country report.

So, while doctors recommend that people – especially those with small children – leave Ulaanbaatar for fresh air, this is a luxury that few can afford.

“I don’t want to be pregnant again, I’m too afraid,” says Oyun. “When pregnant, both times during winters, I was constantly afraid that air pollution would lead to birth defects.”

In the mid-2010s, Mongolia, riding the wave of its mining boom, was hailed as “the world’s fastest-growing economy” by the World Bank. But the global financial crisis and subsequent boom and bust in commodity prices dealt a severe blow to Mongolia, fuelling poverty, unemployment and despair.

A $5.5bn bailout from the International Monetary Fund helped pull Mongolia’s economy off its knees.

In 2018 the country produced 34.4 million tonnes of oil equivalent (TOE) of coal – a record. Overall, the National Statistical Office (NSO) of Mongolia says, the mining industry represents nearly 22 percent of the nation’s revenue for 2019.

Despite this, coal is not the magic bullet for Mongolia that many believed it to be; it is also a poisoned chalice. It is proving to be a “resource curse”, whereby a country’s over-reliance on one or a limited number of natural resources – in Mongolia’s case, coal and copper – can lead to a failure to invest in other sectors as well as a higher risk of corruption.

In its 2019 report, Freedom House, the US government-funded NGO, highlights increasing corruption levels within the mining sector in Mongolia, despite – or perhaps because of – “vaguely written and infrequently enforced” anticorruption laws.

But most of all, coal is dirty and its over-use has triggered a health and environmental crisis in Ulaanbaatar as well as further afield.

‘There were a lot of people sick’

On the Mongolian steppe, seemingly far removed from the centre stage of the coal industry, the effects of this over-reliance on coal are already hitting the country’s nomadic population hard.

The Batbold family’s ger, camouflaged by snow, sits surrounded by valleys outside Karakorum, the ancient Mongol capital founded by Genghis Kahn.

There are other gers within walking distance, dotted between enclosures for the animals and giant piles of wood to heat these rudimentary homes. Other than that, these families live alone – as Mongolian nomads have done for centuries.

It is a way of life. But Mongolia’s nomads, reliant on livestock and mostly contributing to the cashmere industry, now stare the consequences of climate change right in the eye, embodied by a man-made catastrophe they call the “dzud”, a term for the severe winters marked by starvation, cold and financial hardship that they now endure every year.

Millions of livestock have died due to the dry summers followed by the extreme winters over the past decade in Mongolia, according to a 2018 report by the research journal, Nature.

It states: “Alleviating the impacts of climate change on herder communities, through strengthening adaptive capacities, risk reduction strategies, including reducing herder vulnerability to future hazards, and resilience in degraded environments, will be a crucial challenge.”

This extreme weather phenomenon is the scourge of every nomad’s daily life. “Here, winter starts in the summer,” says Chantsaldulam Batbold.

She is paying “tribute” to the sky, mountains and soil outside the family ger by throwing spoons of fresh cow’s milk into the air, in a kind of offering. “We thought the summer would be good; it wasn’t. There is no grass for the animals and the winter is getting harder.”

Every day, the family takes the livestock – 100 cows, goats, horses and sheep – out in search of suitable pastures. “We can’t get enough hay to them due to higher prices, and even if we had, it’s not nutritious enough,” says Banzragch Batbold as he saddles his horse. Chantsaldulam hands him a thermos with warm suutei tsai, a traditional Mongolian beverage consisting of milk, salt, tea leaves and water.

The nearby river is ice-covered and melted snow serves as drinking water. All seven Batbold children, who range in age from nine months to 10 years, see their father off and play outside until their mother hauls them back inside. Three of them, who attend boarding school in Ulaanbaatar, returned from school with the flu just before Christmas – another effect of the pollution, Chantsaldulam suspects.

“There were a lot of people sick at the school, as is usually the case this time of the year,” she says.

As inside any typical Mongolian ger, life is divided into sections: the kitchen area; beds; a couch for visitors; a shrine for valuables, family portraits, clothing and a TV set. The heart of the ger is the stove, which provides heat during the harsh winter season.

The temperature can reach 30°C inside the ger while outside it gets as cold as minus 20°C.

Climate change has been particularly extreme in Mongolia, where the average temperature has increased by 2.2°C since 1940 – compared to 0.85°C for the planet in general – causing havoc with weather patterns.

According to a 2019 report from the European Institute for Asian Studies, Mongolia’s mining sector is to blame for this and, therefore, for the resulting compromised biodiversity and worsening public health. The report states: “Mining activities and mining-related infrastructure projects have, indeed, contributed to the rapid increase of CO2 emissions in the country, the vast erosion of pasture land and deforestation.”

The choice for those living on the ground? Put up with it or get out.

“On the steppe, you’re on your own,” laments Chantsaldulam. Many have opted for the latter, heading to Ulaanbaatar’s ger districts, where thousands of former nomads-turned-city-dwellers reside in a socioeconomic parallel society.

In 2001, Ulaanbaatar’s total population was 630,000; in 2014 it had reached over one million. It is now 1.6 million. One in four inhabitants of Ulaanbaatar lives in what the International Monetary Fund describes as “shanty towns” – the ger districts – and 28.4 percent of the population are living below the poverty line, according to Mongolia’s National Statistical Office.

Chantsaldulam and Banzragch know both worlds but fancy neither; climate change has altered everything, everywhere.

“When you walk alongside your animals, day in and day out for many years, you realise what’s at stake,” says Banzragch. “The wheel of life is shifting on its axis.”

Extreme measures

Ulaanbaatar was called Urga (“Palace”) until 1924, when, as the capital of the new Mongolian People’s Republic, it adopted its Soviet-style name, which means “Red Hero”.

Mountain plateaus surround the city, which functioned as a Buddhist meeting point in the 1700s. Winds come from Siberia in the north, turning the winters into long, cold periods of existence under a veil of smog. At 1.6 million, the population of the city has trebled since 1989. Ulaanbaatar’s undeveloped outskirts have swelled like balloons and these ger districts lack sustainable access to electricity and clean water, making coal – now, government-issued briquettes – the only option for cooking and heating.

As a result, the authorities blame Ulaanbaatar’s ger districts for 80 percent of the recent years’ hazardous air pollution levels which are taking their toll on residents. Small children, the elderly and pregnant women are particular prey for infections, viruses and diseases, which spread easily in poorly ventilated facilities.

A preschool named “63” in Gachuurt, eastern Ulaanbaatar, has taken extreme measures to protect its children.

“We’ve installed air purifiers, updated ventilators and keep all windows closed at all times to guarantee our 150 pupils access to fresh air and clean food,” says principal Nyamsuren Enkhtsetseg.

The view through the window on the second floor, however, shows the preschool’s neighbour is a heating plant. Raw coal emissions from it sweep over a part of Ulaanbaatar where the ban on raw coal has yet to be implemented, forcing all children to wear protective masks whenever they play outside. “We’ve begged the authorities to remove it; but nothing’s happened,” sighs Enkhtsetseg.

In December 2018, the Mongolian government banned the use of unprocessed, raw coal for domestic cooking and heating, a directive which has been implemented in six of Ulaanbaatar’s nine düüregs (districts) so far. The ban will take effect in the remainder in 2021.

Government-issued coal briquettes, which are “cleaner” than raw coal but are still rationed, provide a substitute and have helped to nearly halve the city’s air pollution levels. The briquettes, made from coal powder and coking coal from the southern Gobi region, are produced at a newly built plant in Ulaanbaatar and sold at certified “briquette stations” throughout the capital.

Residents who need heating coal must show ration vouchers to buy them for $1 a bag – no voucher, no briquettes.

At one of the distribution sites, a woman without her briquette coupon is trying to purchase a bag, anyway. The briquette vendors shake their heads; there is nothing they can do. If they sell to unauthorised customers they risk a 30 percent salary deduction.

“How am I supposed to heat our home tonight?” the woman asks, then turns and leaves the station, her two children trying to keep up with her.

It is doubtful that rationing will be respected by everybody. People will always find a way around it – especially when the cold bites. “People are using briquettes just like the old raw coal and burning them the same way,” Byambajargal Losol, a physicist at the Mongolian Science Academy, told AFP in November last year. “The briquettes are thick and compact so they require twice as much oxygen to burn, compared to raw coal.”

But the raw coal ban signals political responsibility, proclaims Gabymbyme Haldai, head of Ulaanbaatar’s Air Pollution Reduction Department. “The briquette transition has halved our air pollution levels in just one winter. Now, the production capacity at the briquette plant must increase and the ban implemented in wider areas.”

Haldai sees no problems with Mongolia’s dependence on coal. “Coal makes Mongolia energy independent,” he states.

Questions about sustainable energy investments seem to annoy him. “I don’t know where you come from or what energy sources you use. Here, we experience extreme weather conditions,” Haldai says.

The ban on raw coal, however, “will only take Mongolia so far”, says Alex Heikens, UNICEF’s Mongolia representative. “Its visible positive results might end up counterproductive. Only 90 percent decreased air pollution will make any real difference to climate and people’s health.”

Eight residents of Ulaanbaatar have suffocated to death in their sleep due to carbon monoxide poisoning after burning briquettes, and 1,000 people have been hospitalised with symptoms of nausea and breathing difficulties since October last year.

‘Times have never been so hard’

Government attempts to curb pollution – most notably by banning the use of raw coal in some areas – have brought new hardships to those reliant on the mining industry for a living.

Darkness falls over the industrial remnants of Nalaikh’s now-closed and abandoned open-pit coal mine, 40km east of Mongolia’s capital, Ulaanbaatar. The once state-owned mine shut down because of the fall in demand for raw coal, but the coal reserves are still there. They are now hauled out of narrow, small-scale shafts run in semi-illegal fashion, providing middlemen with raw coal to sell on the black market.

A dirt road ends at a 120m-deep shaft here. Five miners drink Coca-Cola and smoke cigarettes inside a ger, which has been raised next to the shaft. “I’ve been a miner since I was a kid,” says Khurelshagai, smiling at clips of his daughters on his phone. “But times have never been as hard as today.”

From the 1950s, Nalaikh Coal was a major local job provider and an important provider of energy to Ulaanbaatar. But it was also the primary contributor of carbon dioxide emissions and high levels of hazardous, atmospheric particles called PM2.5. These microscopic particles enter the lungs and the bloodstream, and are responsible for turning Mongolia’s capital into one of the world’s most polluted cities.

“There is really no affordable alternative [to coal] in terms of clean fuel,” said Delgermaa Vanya, health and environment officer at the World Health Organization in a 2019 report. “As a result, in the winter months over 600,000 tonnes of raw coal are burned for heating in the city’s approximately 200,000 gers, accounting for about 80 percent of Ulaanbaatar’s winter pollution.”

The ban on raw coal has helped Mongolia’s ecological and financial climate – but it has also rewritten life in Nalaikh, where locals talk of shattered businesses and a lost future. Industrial-scale coal production is a thing of the past there, although small quantities of raw coal are still hacked and scavenged from semi-illegal, squatted shafts and sold, either to Ulaanbaatar’s remaining raw-coal heating plants or on the black market.

Mongolian democracy is primarily embodied as the financial liberalisation of big industries, says Tserengund, one of the miners. He is having a smoke on the slope overlooking the 120m-deep narrow shaft. He has coughed, dug and stooped his way through narrow shafts for 20 years to provide for his wife and son. His only reward will be a broken body. “The boss can’t pay me; I just get daily coal rations for heating and cooking. But I have no other choice, we don’t want to freeze to death.”

Night temperatures fall close to minus 30°C. Nalaikh’s last coal miners catch their breath upon the slope; they have the air of guardians of a lost industrial kingdom. Tserengund looks around, seeing more than just the piles of gravel, debris and a silent industrial no-man’s land.

“This used to be a place of pride,” he laments. “Both my grandparents and parents worked here. In the summers, cows pastured in the surrounding hills. Back then, the place was green.”

“Now,” he sighs, “It looks like a war zone.”

Air pollution may aggravate nasal suffering with colds and seasonal allergies

People who get rhinitis – an inflamed or congested nose – from colds or allergies may feel much worse if they’re exposed to high levels of air pollution, a recent study suggests.

Rhinitis usually involves some combination of congestion, sneezing, nasal irritation and sometimes a reduced sense of smell, and it affects up to half of the world’s population, the study team writes in Journal of Allergy & Clinical Immunology.

“Breathing polluted air will cause inflammation and oxidative stress on the respiratory tract,” said lead study author Emilie Burte of INSERM in Villejuif, France.

“That probably will increase the frequency or severity of rhinitis symptoms,” Burte said by email.

Even though rhinitis is especially common among people with asthma – a condition that’s aggravated by air pollution – research to date hasn’t offered a clear picture of how air quality impacts the severity of rhinitis.

For the current study, researchers examined data on air pollution exposure and symptom severity for about 1,400 people with rhinitis in 17 European cities.

Two types of pollutants in particular were associated with worse rhinitis symptoms: nitrogen oxide, a byproduct of fossil fuel combustion that contributes to smog; and so-called PM 2.5, a mixture of solid particles and liquid droplets smaller than 2.5 micrometers in diameter that can include dust, dirt, soot and smoke.

People in cities with the highest levels of PM 2.5, or fine particulate matter, reported the most severe rhinitis symptoms.

Each increase of 5 micrograms per cubic meter of air (mcg/m3) in concentrations of fine particulate matter was associated with a 17% higher chance that people with rhinitis would experience severe symptoms, the study found.

Fine particulate matter was associated with worse congestion, nasal irritation and sneezing.

Nitrogen dioxide was also tied to more severe rhinitis, particularly for symptoms like nasal discharge and congestion.

The pollutants exacerbating rhinitis in the study have long been linked to traffic fumes, with worse air quality around major roadways in cities around the world.

While the study wasn’t designed to prove whether air pollution causes rhinitis or makes symptoms worse, it’s possible that each kind of contaminant in the air does its own type of damage in the respiratory system, Burte said.

People prone to colds and allergies can’t do much to prevent pollution from making rhinitis worse, aside from staying indoors, said Yaguang Wei, an environmental health researcher at Harvard University in Boston who wasn’t involved in the study.

People can pay attention to air quality alerts for their city or community and plan to stay indoors or at least avoid vigorous activity outside during peak pollution times.

“For indoor air pollution, air purifiers can clean indoor air and protect your family, especially for children and the elderly,” Wei said by email.

People can also do their part to reduce traffic fumes.

“Using public transportation can help reduce air pollution emissions,” Wei said.

Deadly air pollution is blowing into your state from a surprisingly large source

Air pollution doesn’t respect borders. A power plant in one place often ends up killing people who live far downwind. Now, a detailed analysis of how air pollution moves in the United States reveals that since 2005 premature deaths caused by two of the biggest polluters—power plants and traffic—have fallen significantly. The bad news: Deaths from residential and business emissions, like those from heating and burning trash, grew nearly 40% over the same period.

Air pollution kills when particles from burning coal, wood, or natural gas react in the atmosphere to create ozone and soot. Those particles damage airways and the cardiovascular system. In the United States, such pollution causes many deaths each year; estimates range between 90,000 and 360,000.

But figuring out how all the various sources of pollution spread and threaten health is a herculean task. So Steven Barrett, an atmospheric scientist at the Massachusetts Institute of Technology; aerospace engineer Irene Dedoussi, now at Delft University of Technology; and colleagues used a computer model of winds and atmospheric chemistry. They added data from U.S. Environmental Protection Agency (EPA) air pollution surveys to study large sources of pollution, including power plants, industry, roadways, and homes and businesses. The model revealed how the pollution moves from state to state, reacting with other compounds to form harmful particles. Because people are exposed to pollution from multiple sources, the model estimated the contributions from all these sectors and their added risk of death.

There has been progress since 2005. Overall, about 30,000 fewer people died from air pollution in 2018, they report today in Nature. Deaths related to power plant emissions fell 65% to 8500, and deaths related to traffic pollution fell 50% to 18,600. Much of the former improvement, Barrett says, comes from tighter EPA regulations and economic factors that favor cleaner burning natural gas over coal.

“All those years of effort to control power plant pollution, and to some extent road transport, have dramatically reduced the contributions of those sources—and that’s good news,” says Dan Greenbaum, an air quality expert and president of the Health Effects Institute, a research organization that studies air pollution.

But the benefits depend on where you live: Forty-one percent of premature deaths from air pollution still result from out-of-state emissions, the study found. “That’s a startlingly high figure,” says John Walke, who directs the clean air, climate, and clean energy program at the Natural Resources Defense Council, an environmental advocacy organization. “This is the first time that I’ve seen such a precise estimation … attributed to upwind emissions.”

Power plants remain the dominant cause of these out-of-state deaths because those emissions travel longer distances. Greenbaum says the findings reinforce the need to tackle air pollution with a national approach, as EPA has done. Giving more power to the states to regulate air quality would jeopardize progress, he says.

Barrett says he was surprised by a different finding: the significant, and growing, impact caused by residential and commercial pollution. Such emissions caused 20,400 premature deaths in 2005, a number that rose to 28,200 by 2018. But the 38% increase isn’t due to large increases in air pollution. Instead, as less sulfur dioxide and nitrogen oxides enter the atmosphere from coal-burning power plants, the ammonia and nitrogen oxide byproducts of residential and commercial burning are more likely to form harmful particles.

Dan Goldberg, who researches air pollution at George Washington University, was also surprised by the increase. Because commercial and residential emissions are understudied compared with other sources, he’s not yet fully convinced by that trend. But given the shifting burden, the researchers calculate that a 10% reduction in air pollution from residential and commercial sources would yield more than three times the health benefits of a 10% reduction from power plants.

Still, most experts would be loath to have to choose which sector to clean up. “For me,” Barrett says, “the right answer for emissions is ultimately zero.”

More evidence links ozone pollution to premature death

People who live in cities where the air is polluted by factories and traffic fumes may not live as long as they would have with cleaner air, a recent study suggests.

Researchers focused on ozone, an unstable form of oxygen produced when various types of traffic and industrial pollution react with sunlight. Worldwide, about four in five people in urban areas are exposed to ozone levels that exceed safe levels recommended by the World Health Organization, the study team notes in The BMJ.

The study looked at ozone levels and deaths in 406 cities in 20 countries around the world. It found that overall, about 6,000 deaths a year in those cities could be prevented if stricter air quality standards reduced ozone levels below the WHO-recommended maximum of 100 micrograms per cubic meter of air (mcg/m3).

“Our study confirms the evidence from previous studies on the adverse health impacts associated to the exposure to ground-level ozone,” said lead study author Ana Maria Vicedo-Cabrera of the University of Bern in Switzerland.

“Patients should be aware of the risks of the exposure to high levels of ozone, in particular when their health is already compromised,” Videco-Cabrera said by email.

Air pollution has long been linked to higher risks of heart attacks, strokes, asthma attacks and other respiratory problems with the potential to shorten people’s lifespan. Less is known, however, about how much exposure to ozone levels higher than WHO limits might directly impact longevity, the study team notes.

In the current study, researchers examined data on ozone levels and more than 45 million deaths between 1985 and 2015.

On average, a 10 mcg/m3 increase in ozone during the current and previous day was associated with a 0.18% increased risk of death, the study team found.

Even when cities had ozone concentrations below WHO limits, levels between 70mcg/m3 and 100mcg/m3 were still associated with an increased risk of death during the study period. This suggests that even stricter air quality standards might be needed, the study team concludes.

The study wasn’t designed to determine whether or how ozone exposure might cause premature deaths.

The researchers also didn’t have enough data from certain regions of the world, including South America, Africa, and the Middle East, to craft a truly global estimate of how ozone exposure impacts longevity. The ozone assessment also didn’t look at outdoor versus indoor air quality.

“We don’t fully understand the entire pathway from ozone exposure to mortality,” said Dr. Frank Gilliland, a researcher at the University of Southern California in Los Angeles who wasn’t involved in the study.

“We do know that ozone is a toxic gas that produces airway and systemic oxidative damage and inflammation when inhaled these adverse effects are likely to have large impacts on those with health problems such as respiratory conditions or who are frail from aging,” Gilliland said by email.

Cairo car drivers exposed to dangerous levels of pollution, new study finds

Car drivers in Cairo are exposed to dangerous levels of air pollution, finds an unprecedented new study from the University of Surrey.

Greater Cairo, which is the sixth largest city in the world, is home to 2.4 million cars and it is thought that particulate matter (PM) concentration – i.e. air pollution – is the cause of around 10 per cent of premature deaths in Egypt.

In the study ‘Car users’ exposure to particulate matter and gaseous air pollutants in megacity Cairo’ published in Sustainable Cities and Society, a team led by Surrey’s Global Centre for Clean Air Research (GCARE), together with the American University in Cairo, investigated the contributing factors that determine particulate matter (PM) exposure levels while in a vehicle – for different car settings (open window, closed window, or with air conditioning (AC) on), during different times of the day and across various commuter routes (cross city and inner city).

The results found that Cairo motorists who drive with their windows open can be exposed to 65 per cent more PM10 (coarse particles) and 48 per cent more PM2.5 (fine particles) than those who drive with windows closed and the AC on. However, many car owners simply do not have AC in their vehicles and are exposed to levels of PM10 and PM2.5 as high as 227 and 119 μg/m3 while driving through cross-city routes.

The study further found that evening peak hours are more congested, causing drivers to get exposed to higher pollution concentrations compared to morning peak hours.

The team also discovered that Cairo’s close proximity to the desert and its low precipitation rates are contributing factors to higher concentration of PM10. GCARE found that areas with high construction activity or unmaintained roads also feature higher levels of PM10.

Professor Prashant Kumar, Founding Director of GCARE at the University of Surrey, said: “Air pollution causes seven million premature deaths worldwide, disproportionately affecting poor and vulnerable communities and exacerbating inequalities in official development assistance (ODA) countries. Knowledge is invaluable in our battle against climate change and air pollution, which is why we hope that our study -the first of its kind – is not the last.”

Air pollution has major impact on children in sport, study warns

Breathe GB warns of damage to lungs and performance in survey of training grounds

Britain’s future sporting performance could be hampered by air pollution because some training grounds are in areas with dangerously high pollution levels, a report has revealed.

The Breathe GB study analysed pollution levels at 94 sporting sites, with one of the highest recorded levels at Birmingham’s Perry Park, host of the 2022 Commonwealth Games.

Other important training grounds, such as the running track where Sir Mo Farah and Christine Ohuruogu trained, have pollution levels that breach World Health Organization (WHO) recommended limits.

The study suggests children exercising in areas of high pollution will experience stunted lung function that will limit their future sporting performance.

Dr Ian Mudway, a senior lecturer in respiratory toxicology at King’s College London, said: “A child growing up with asthma in a polluted city will have worse symptoms that will limit their potential to train … which is likely to have an impact on their optimal level of performance.”

Jonathan Grigg, a professor of paediatric respiratory and environmental medicine at Queen Mary University, said: “There is very strong evidence that exposure to air pollution stunts children’s lung function. Children with clinically low lung function will have reduced exercise capacity.”

At the launch of the report on Tuesday morning, Mark Bergin, a PE teacher from Manorfield primary school in Poplar, east London, said: “There are elements that we can see now because there is such an increase in the number of children who have asthma pumps; I’ve noticed that over the last 10 years or so of working in education.”

To produce the report, campaign group The Air Team spoke with senior respiratory consultants, as well as leaders in physical education, to assess the effects of air pollution on children’s lung function and sporting ability.

They also assessed air pollution at 94 sports sites in England and found that 25 broke WHO recommended limits, while 52 came close to the threshold.

Perry Park was the third most polluted of the sites across London, Birmingham, Nottingham, Salford and Sheffield, with an annual mean level of 50 micrograms of nitrogen dioxide (NO2) a cubic metre of air (μg/m3) – the WHO recommends a safe level of 40μg/m3.

The training grounds of Ridgeway Rovers, where David Beckham and Harry Kane formerly played, and Alpha & Omega FC, Raheem Sterling’s former youth team, have fine particulate matter levels (PM2.5) of 11, above WHO recommended limits.

St Augustine’s Hall, home of the Victoria Park Harriers and Tower Hamlets athletics club, had the highest air pollution levels out of those assessed, with 67 NO2 μg/m3.

Ben Paul, an Air Team campaigner who lives in Bloomsbury, central London with his 10-year-old son, said: “It’s like how it took time for the full health impacts of smoking to be understood. I think this could be a ticking time bomb for our children.

“Kids’ lung capacity can reduce by up to 14% if they live in a high pollution area. Wouldn’t it be great if we could get 14% more medals at the next Olympics?”

The Air Team is calling on sports organisations, MPs, schools and athletes to back their Breathe GB campaign. Its spokeswoman, Anella Wickenden, said: “If you care about British sport, you need to care about air pollution.”

Sofia’s Air is Dangerous Again

The air in Sofia was dangerously polluted last night, according to official data from the municipality, BNR reported. Exceedance of the reference limits for the content of fine particulate matter in the air has been reported by all stations except the one in the Kopitoto mountain area and the non-working one in the Nadezhda neighborhood.

Once again, Sofia ranked 18th in the world in terms of air pollution.

The pollution levels are not high enough for a green ticket to be introduced, but other measures, such as checks on construction sites and other industrial and household sources of pollution, will be in place.

According to the European Air Quality Index, except in Sofia, there are also dangerous exceedances of fine particulate matter in Plovdiv, Veliko Turnovo, Ruse and Pernik.

Study details how auto emissions pose human health problems worldwide

Ultrafine particles in the atmosphere are unregulated, according to the World Health Organization, but a team of international researchers that includes a Texas A&M University professor and two graduate students has found that auto emissions are a key factor in the creation of the particles, and pose a significant health problem in many urban areas.

Renyi Zhang, Texas A&M distinguished professor of atmospheric sciences and the Harold J. Haynes Chair in Geosciences, and colleagues from the University of Texas at Austin, the University of California-San Diego, the California Institute of Technology, Johns Hopkins University and several Chinese universities have published their work in the latest issue of the Proceedings of the National Academy of Sciences.

The team studied auto emissions relevant to urban areas, especially Beijing, which has some of the highest levels of auto exhaust pollution in the world.

It found that auto exhaust plays a part in the creation of large amounts of ultrafine particles. These tiny particles have been proven detrimental to air quality and human health, and have been linked to birth defects.

“This has been an emerging area for research,” Zhang said. “Ultrafine particles can penetrate easily through human lungs and reach many vital organs. The impacts of ultrafine particles on human health can be far-reaching. Currently, ultrafine particles are unregulated. They can be present in high concentrations, but you still see blue sky.”

The air quality standards established by the U.S. Environmental Protection Agency (EPA) only limit the mass concentration of PM2.5—referring to particles smaller than 2.5 microns—for human health concerns. Ultrafine particles have negligibly small masses and are produced more efficiently when the atmospheric PM2.5 levels are low, according to the study.

“Our measurements are representative of typical urban environments worldwide, since the gasoline fleet of the commonly used vehicle models in China is equivalent to those in Europe and the United States,” the researchers wrote in the paper.

“The problem of ultrafine particles is as important in China as in the U.S. Reduction in PM2.5 to improve air quality could exacerbate pollution of ultrafine particles,” Zhang said.

The implementation of the Clean Air Act in 1990 has resulted in noticeable reduction in PM2.5 over the United States. “Protecting public health needs simultaneous reduction in both types of particles,” Zhang said. “Sound science is essential to guide the regulatory policies.”

While finding ways to reduce ultrafine particles will require much more research, Zhang says drivers using electric cars would almost certainly help. But that could be years in the future, since electric vehicles currently make up less than 1 percent of over 1 billion vehicles on roads worldwide.

Zhang said the study shows for the first time “that traffic emissions are a major source for ultrafine particles. Our studies show that aromatic organic compounds from auto exhaust form these ultrafine particles. They form in any cities from car exhaust, such as Houston, New York City, and Washington, D.C. Residents who live close to highways or congested roads are particularly vulnerable.

“This is a frontier area in air pollution. Producing close to 1 million nanoparticles per cc in air is a serious matter of concern,” he said.
