Air pollution in Europe

France, Italy, the United Kingdom, Spain or Bosnia-Herzegovina…. All these countries, whether big or small, are being threatened with the same problem: air pollution.

According to the World Health Organisation, this is now the environmental factor causing the greatest concern for our health. The European Environment Agency states that around 90% of the urban population in Europe is exposed to pollutants which are considered to be harmful.

“This hike in pollution is partly due to the increased emissions caused by more heating being used to combat cooler temperatures,” explains weather forecaster Lionel Guiseppin. “Also, other contributing sources of pollution are traffic and manufacturing. These factors combine to create an accumulation of pollution. “

The European Union is trying to find solutions to this dangerous threat. A directive governing national emissions levels has been issued (the PEN directive) and the EU has also set limits, for the first time, on the ambient concentrations of fine particles.

On a national scale, each member state has taken emergency measures to limit the harmful effects.

Many European towns, especially in France, have reduced the speed limit in built up areas from 50 to 30 km per hour. The aim is to encourage the use of bicycles. The introduction of the ruling concerning alternate number plates, although quite efficient, has caused problems for public transport.

“I think it’s a good thing but at the same time it is a bit of a pain,” says French commuter Laurice Harrow. “As it’s free today, people are no longer using their cars but the trains are full and we no longer have any space, it’s a real pain.”

The second solution offered by Public Authorities is to ban vehicles with a high level of pollution. In Germany, ignoring this directive can lead to a fine of up to 40 euros while in Sweden, drivers may have to pay 113 euros. In London, the fines are higher still and can reach approximately 1200 euros for heavy goods vehicles.

Whilst waiting for the benefits of these solutions to take effect, some citizens have already taken measures. Anti-pollution masks are slowly but surely infiltrating the large European towns.

Forget Beijing, world’s worst air has Mongolians seeing red

If you think air pollution in China has been bad, consider Mongolia.

Levels of particulate matter in the air have risen to almost 80 times the recommended safety level set by the World Health Organisation (WHO) – and five times worse than Beijing during the past week’s bout with the worst smog of the year.

Just as the Chinese capital contends with pollution from the surrounding industrial province of Hebei and coal-fired power plants in the northern provinces of Inner Mongolia and Shaanxi, Mongolian power plants working overtime during the frigid winter belch plumes of soot into the atmosphere, while acrid smoke from coal fires shrouds the shanty towns of the capital, Ulaanbaatar, in a brown fog.

Angry residents held a protest, organised via social media, on December 26. In minus 20 degree temperatures, protesters gathered outside government offices to shout “smog is a silent killer” and “we can’t breathe”.

The level of PM2.5, or fine particulate matter, in the air as measured hourly peaked at 1985 micrograms per cubic metre on December 16 in the capital’s Bayankhoshuu district, according to data posted by government website agaar.mn. The daily average settled at 1071 micrograms that day.

The WHO recommends PM2.5 exposure of no more than 25 micrograms over 24 hours.

In Beijing, the year’s worst bout of noxious smog prompted officials to issue the year’s second red alert last week and order 1200 factories to close or cut production. Earlier this week, PM2.5 levels exceeded 400 in the capital, and Chinese officials on Tuesday cancelled 351 flights because of limited visibility. The highest daily average in the past week, on Wednesday, registered 378. Worse, the PM2.5 reading in Shijiazhuang, capital of Hebei, exceeded 1000 micrograms per cubic metre earlier this week, according to the China National Environment Monitoring Centre.

But Mongolia’s contracting economic growth and a widening budget gap have left authorities few resources to fight the dangerous smog.

After first cutting the night-time electricity tariff by 50 per cent to encourage residents to heat their homes with electric heaters instead of raw coal or other flammable material that is often toxic, Prime Minister Erdenebat Jargaltulga announced on Friday that the tariff would eliminated entirely as of January 1.

Longer term, he proposed building apartments to replace makeshift housing using a loan from China, doing more to encourage electric heating, and reducing poverty to slow migration to the capital, according to a government statement.

The conversion of ger districts, where hundreds of thousands of people live in makeshift homes including tents, into apartment complexes has so far been stymied by an economic crisis that has pushed the government to seek economic lifelines from partners including the International Monetary Fund and China.

On Wednesday, Defence Minister Bat-Erdene Badmaanyambuu announced that a 50-bed wing of Ulaanbaatar’s military hospital would open up for children with pneumonia, as city hospitals were filled to capacity.

Public anger over the government’s handling of pollution has been growing on social media, where residents share pictures of the smog, encourage methods of protection and call on the government to do more to protect citizens. The latest trend Friday had Mongolians changing their profile pictures on Facebook to show themselves wearing air pollution masks.

The air pollution protest next week was being organised for Sukhbaatar Square, the capital’s central plaza. A crowdfunding campaign to purchase 100 air purifiers for hospitals and schools raised more than $US1400 in five days.

“The hospital I visited today did not have any air purifiers, even though 40 mothers were scattered along a narrow corridor, each with a sick baby in their arms,” Onon Bayasgalan, an environmentalist who organised the crowdfunding campaign, said on Thursday. “They sleep on fold-out cots in the corridors, as the hospital rooms are full of pneumonia cases.”

Earlier this month, the United Nations Children’s Fund (UNICEF) warned of an impending crisis if the smoke levels were not reduced, calling children under five and those still in the womb the most vulnerable.

“Children are projected to suffer from unprecedented levels of chronic respiratory disease later in life,” the UNICEF report said, warning of the rising economic costs of these diseases unless “major new measures” were urgently enacted.

“The alarming levels of air pollution in Ulaanbaatar during the long winter cannot be neglected any longer, as their short- and long-term negative health impact has been demonstrated, especially for children.”

A 2013 study by Canada’s Simon Fraser University concluded that 10 per cent of deaths in Ulaanbaatar were related to complications from air pollution.

“Most of my colleagues’ children are hospitalised or at home struggling with respiratory problems,” Lhagva Erdene, news director at Mongol TV station, said. “We feel helpless and frustrated for the inaction of our government.”

Neither the ministers for foreign affairs nor the environment replied to requests for comment.

Byambasaikhan Bayanjargal, who heads the Business Council of Mongolia in the capital, said he and his family try to stay indoors as much as possible and spend weekends outside the city.

“There have been shifting policies, and that is frustrating,” he said. “There needs to be consistent policy and stability so businesses can find solutions to this problem.”

On Friday, PM2.5 levels in northern Ulaanbaatar peaked at 932 at midday, while the monthly average for December so far was 518. Meanwhile in Beijing, where the government lifted its pollution warning on Thursday, skies were clear and air quality improved.

Utah air getting worse as inversion settles in 

Despite a strong weekend storm, Utah’s air is getting dirtier.

Much of the state is sitting under polluted skies with no immediate end in sight. Across the Wasatch Front — and even beyond — we may be in for several days of air that’s not entirely fit for breathing.

“We’re definitely in an inversion,” said Donna Kemp Spangler, spokeswoman for the Utah Department of Environmental Quality. “Pollution from automobiles, home heating, businesses, industry is really just making the air pollution bad.”

The inversion comes after a whopper of a storm over the weekend that pounded much of the state. You’d think that might have cleared things up.

“I think it helped,” said Spangler.

Just not enough.

“It has to have the right meteorological conditions which is not just snow falling,” Spangler said. “It actually has to have a punch to it, a little bit of a wind system going to actually push the pollution out.”

So now, with no imminent storms, people in Utah are stuck with smoggy air that isn’t getting any better. The inversion is visible from almost anywhere. Kristy Conlin saw it Tuesday afternoon when she brought her out-of-town friends to an overlook above Salt Lake City.

“My friend from Brazil said, oh, there’s these clouds so we can’t see anything,” Conlin said. “When I told her it was an inversion, she was very surprised.”

Of course, it’s not just tough to look at. For children and others who are sensitive to pollution, it can be hazardous.

“We’re talking about really small particulate pollution that gets lodged in your lungs,” said Spangler.

Officials urge people to cut down on driving and wood burning — small things that can make a difference. Staying inside can help, too, if things get really bad. But as of now, Conlin isn’t there yet.

“You have to live still, I guess,” she said, looking out over the valley. “You can still see the organization of the city so it’s good.”

Traffic calming measures in Madrid: Madrid City Hall ups traffic-calming measures in bid to control pollution 

“Level 2” protocol will see parking restrictions for non-residents inside M-30 beltway until nitrogen dioxide levels fall

High pollution levels in the Spanish capital will once again see Madrid City Hall impose traffic calming measures tomorrow, according to an announcement made by the council on Tuesday. The head of the environment department, Inés Sabanés, signed the activation of the “level 2” protocol today, which will be kept in place until air contamination falls.

On Monday, the council took the decision to introduce 70km/h speed limits on the M-30 beltway and access routes into the center of Madrid. Given expected high pollution levels, from Wednesday there will be no street parking for non-residents within the boundaries of the M-30.

The current restrictions were sparked after measuring stations on the Castellana boulevard, in Plaza de España, Cuatro Caminos and Ramón y Cajal detected more than 180 micrograms of nitrogen dioxide per meter cubed during two consecutive hours. The clear weather conditions currently forecast for the city will not help the situation.

The measures to be put into place tomorrow will not affect motorbikes or scooters, nor motorists who have residents’ parking permits. Also exempt from the parking restrictions are people transporting people with limited mobility, taxis, local business owners in the affected areas, official vehicles, removal firms or emergency services. The fine for not observing the parking restrictions can reach up to €90, although if settled immediately the amount is half that.

Speed limits were put in place last week within the M-30 due to high pollution levels, while parking restrictions were last put in place toward the end of October. Madrid is one of a group of European cities that is considering banning diesel cars from its center by 2025.

Turin smog puts half of children at health risk: study 

Half of children living in the northern city of Turin are at increased risk of illness due to pollution, new research shows.

The high levels of air pollution lead to a mutation in DNA, according to the ‘Mapec Life’ study which studied the effects of pollution on children and was presented on Wednesday.

Researchers analyzed DNA samples from children aged between six and eight in Turin, Brescia, Lecce, Perugia and Pisa.

In Turin, 53 percent of these samples from students had at least one micronucleus – an indicator of a mutation in DNA.

While this does not present an immediate health risk and the mutation is not passed on to future generations, over time it can lead to tumours and other chronic diseases.

“We do not want to create anxiety, but we have done this work to understand the effects of smog on children’s biological systems,” explained Giorgio Gilli, one of the professors behind the study.

The development of pollution-induced diseases can be mitigated through other lifestyle changes, such as exercise and health eating, and aggravated through factors including passive smoking, the researchers found.

On Thursday, the headteacher of one of the schools where students participated in the study, told Repubblica “we all know that our children are breathing poor quality air” but added “it’s not Chernobyl”, referring to the Ukrainian city left uninhabitable by a nuclear disaster.

At the report’s presentation, Turin’s councillor for the environment, Stefania Giannuzzi, said the results “would be considered and evaluated” by city authorities.

“One of our jobs is to protect weaker sections of society, including children, from the effects of pollution.”

Recent days have seen high levels of smog in the city, which has reacted by introducing blocks on the most polluting vehicles. The clouds began to clear however with the first snowfall of the year on Monday.

Specific molecular events that could explain allergic reactions to air pollution

Scientists at the Immunology Frontier Research Center (IFReC) at Osaka University, Japan have pinpointed a specific molecular events that could explain allergic reactions to air pollution. These findings provide a new therapeutic candidate to treat asthma and related respiratory diseases.

Photos of cities darkened by pollution are becoming evermore common. These same cities are seeing a rise in cases of asthma and other respiratory ailments, marking a relationship between pollution and health costs. Nanoscopic particulates polluting the air enter the lungs to cause the allergic reactions. Which immune-related events in the lung lead to this response, however, are unclear.

“We found that particulates kill macrophages, which then go on to release interleukin-1a (IL-1α),” explains Etsushi Kuroda, who first-authored a new study in Immunity that indicates IL-1α triggers a series of events that causes respiratory illnesses. The release of IL-1α in mice primed the lungs for inflammation when the mice were later exposed to an allergen. Kuroda added, “Particulates that did not kill macrophages did not cause an allergic reaction.”

However, the vulnerability of macrophages to particulates remains unclear, which is why understanding the events following IL-1α secretion may be key to prevention and treatment.

“IL-1α secretion was followed by the formation of iBALTs. iBALTs are frequently found in infected or inflamed lungs and in patients with asthma,” said Osaka University Professor Ken J. Ishii, who led the study. The increase in iBALTs led to an increase in IgE antibodies, which intensified the immune response. On the other hand, mutant mice that were insensitive to IL-1α did not produce iBALTs and reduced IgE responses.

The presence of iBALTs would suggest that a human population could remain susceptible to high levels of asthma attacks even on clear days, as the iBALTs could form on days of high pollution, but the patient could then be exposed to the allergen much later.

This finding suggested that iBALTs could prime the lungs to an allergic reaction, which is why Ishii believes that iBALTs could make a promising therapeutic target to combat the rise of respiratory illnesses associated with air pollution. But first, he said, “we must identify the molecular signals and key chemicals that form these iBALTs.”

Madrid Speed Limits Lowered As Pollution Levels Rise Again

Limit re-set at 70 km/h on the M-30 and other main roads in Madrid

The Town Hall of Madrid announced on Wednesday evening that the level of air pollution has risen once more to higher than the established threshold, and that in consequence the maximum speed limit on the M-30 motorway and the main roads leading into the city centre was to be reduced from 90 to 70 km/h on Thursday.

The permitted amount of nitrogen dioxide was exceeded at the weather stations of Fernández Ladreda and Villaverde on Wednesday and the weather forecast is not favourable, according to the Town Hall press release, and while the speed restrictions are in place members of the public are requested to use public transport rather than private vehicles whenever possible. The restrictions will remain in place for as long as the level of nitrogen dioxide remains above 180 micrograms per cubic meter of air, and information regarding the situation on Friday is to be published Thursday morning.

China Battles Worst Air Pollution of the Year

China suffered its worst air pollution of the year recently.

More than 70 Chinese cities released warnings to citizens in the last few days about pollution reaching dangerous levels.

The poor air quality led the government to order factories, some power plants and schools to close. But there were reports that some local officials were not obeying the orders.

In one city in northern Hebei province, people wrote on social media that schools were kept open although the area had the highest pollution threat. Media reports in the central province of Henan also showed pictures of students completing school activities in the dirty open air.

State-run news agency Xinhua reported that an official in Henan province said factory production was continuing. The official said up to 4,000 factories had not stopped or limited production as ordered by the government. Records of power use at the factories showed little change in the amount of production.

The Ministry of Environmental Protection said in a statement Monday that only “a small number of businesses” had not taken the bans seriously and continued operations.

Driving restrictions were also put in effect and hundreds of flights were delayed or cancelled in Beijing because of poor visibility.

The ministry said more than 100,000 drivers in Beijing had been fined for violating the traffic bans.

The World Health Organization measures air quality by the amount of small, particles in it, known as PM2.5. Small particles of this size are easily breathed in and can damage the lungs.

The WHO identifies a safe level of air quality as containing 10-25 micrograms per cubic meter of PM2.5. Beijing reached dangerous levels of more than 400 micrograms per cubic meter this week.

Weather officials were predicting that nighttime winds could finally push out much of the pollution from Beijing and other cities by Thursday.

Ma Yongliang is a professor with Tsinghua University’s school of environment. He said temporary government restrictions will not solve the nation’s pollution problems over a long period of time.

“In the long run, the pollution problem can only be eased by adjusting the country’s industrial structure, or accelerating the upgrading of [polluting] industries, so as to cut down the emission sources of pollutants,” Ma said.

The professor praised the government’s efforts to reduce carbon-dioxide after an action plan was started in 2013.

But the increased use of coal in winter for heating homes is still a big problem. Reducing these emissions will remain difficult for China’s government as it attempts to find cleaner energy alternatives.
