Murderer Hazy Air Pollution is again over Chinese Capital 

Schools in the Chinese capital kept students indoors and parents brought their kids to hospitals with breathing ailments Tuesday as Beijing grappled with extremely severe air pollution.Residents of Beijing and other parts of northern China were literally breathing a sigh of relief Wednesday, after a cold front and strong winds blew away choking smog that had enveloped the region for about five days. But a haze of recrimination remained.

The pollution that reached over 30 times the World Health Organization’s safe levels Monday

The heavy smog erased the capital’s skylines with a monotonous gray and left buildings just a block or two away hardly discernable. Neon signs barely punctured the gloom, and many Beijingers wore masks of various kinds while walking the streets.

More than 23 cities in northern China had readings of PM2.5 fine particles over 200 — categorized as “seriously polluted” in recent days — with readings in Beijing hitting what state media called an “astonishing” level of 900 Monday, and more than 700 Tuesday, in the latest example of the Chinese capital’s periodic winter “airpocalypse.” (The WHO says any reading over 25 is unhealthy, though China’s official standard is set higher.) Pollution over 500 is officially classified as off the top end of the scale on some monitoring devices.

By Wednesday morning the reading was down to 10 in some parts of Beijing, and one resident posted on social media: “I’ve never been happier to hear sound of winter wind,” while many posted pictures of blue skies and pollution index readings.

But with many recent surveys showing that air pollution is one of the issues the Chinese public is most concerned about, debate about the causes of the smog, and the official response, continued. Officials blamed meteorological conditions — including high humidity, temperature inversion and low winds — for the problem, as well as pollutants including gases released by burning coal to produce energy and heat as cold winter descended on the region in recent weeks.

The Beijing government responded by issuing first a yellow and then an orange pollution alert — the third and second highest levels respectively — which meant closing thousands of factories, halting construction and banning heavy trucks from roads. It also said inspection teams had been dispatched to check coal discharge, “outdoor barbecues” and stubble burning in areas around Beijing and other cities.

However many citizens criticized the authorities for not issuing a red smog alert — the highest level — which they can do after 72 hours of “hazardously” high levels of pollution (over the 300 mark). Beijing environmental officials said however that a red alert “would affect people’s daily life too much,” since it would not only involve closing schools, but halving the number of private cars on roads — and reducing the number of government vehicles by two-thirds.

However environmental groups criticized the decision not to close schools

Children had to be kept inside at break times though some Beijing schools have installed giant inflatable domes with purified air to allow pupils to continue to play sports at times of heavy pollution. Environmental group Greenpeace East Asia, which described the pollution as “shocking,” said Beijing’s “insufficient” warning system had exacerbated what it called “serious danger” to citizens’ health.

There was also a dispute in Chinese media after many Internet users criticized China’s Ministry of Housing and Urban Rural Development, which controls the centralized heating systems for many residential areas in northern China that are fuelled largely by coal-fired furnaces. The ministry denied that it was the prime culprit for the pollution. It said car emissions were the main cause, and turning on the heating — which takes places in the second half of November every year — was “only the last straw.” However Beijing’s municipal Environmental Monitoring Center insisted that coal burning was the main cause of the smog.

The official Global Times newspaper quoted environmental experts as saying that this “buck passing” showed a “lack of pollution source analysis and coordinated efforts to effectively combat pollution.” And though China has pledged vast sums to tackle pollution — the ministry of commerce said this week that China would invest $2.6 trillion in energy conservation and environment in next five years — experts said there was still a lack of government funding for research into sources of pollution.

Shanghai-based news website The Paper quoted an official from China’s Ministry of Environmental Protection as saying that local governments had not taken sufficiently effective action in the face of the smog crisis. The official said local implementation of policies was not as strong as it should be, due to a lack of coordination between different government departments, poor management skills and a lack of staff.

The areas around Beijing were still burning “a large quantity of coal” this week

Quoted one local nonprofit as saying that more than 10 companies were still emitting excessive quantities of pollutants Tuesday. It’s a reminder that even after a decade of increasingly serious air pollution, many in China still lack a thorough understanding of the causes of pollution, according to some experts. This was again highlighted this week, when reports from researchers at China’s Ministry of Environmental Protection that fine particles in smog could cause respiratory diseases, cancer or sometimes death, were given headline status in Chinese media, even though these conclusions did not appear to be particularly new. And an online film explaining the causes of pollution attracted 100 million viewers on the Internet in China earlier this year.

The authorities in Beijing say they are taking long-term action. They had previously claimed that the city had seen improving air quality this year, and have pledged to clean up Beijing’s environment in time for the 2022 Winter Olympics, which will be held in the city and surrounding areas. They have begun to move polluting factories out of the city, and have said all vehicles in Beijing will have to meet Euro VI emissions standards, the world’s strictest, in two years’ time.

Nevertheless coal is still a source of some 80 percent of China’s energy. And an op-ed in the Global Times on Wednesday said the government should realize how imperative it was to “control pollution [ and] seek a balance between the development of Chinese society and environmental protection.”

The article also called on citizens, whose rising living standards have contributed to greater energy consumption and rising pollution, to take responsibility too, and adjust their lifestyles: “We all want to live in a bustling metropolis, in a big house with warm temperatures in winter, while everyone has a car to drive. Yet in the meantime, we all want blue sky. Such a contradiction is hard to resolve,” it said.

However, some people’s response to this week’s smog is likely only to increase electricity consumption and resultant emissions.

Rio 2016 Olympics will have the worst polluted air after the Beijing 2008 Olympics

Athletes competing in the 2016 Rio Olympics might be able to avoid swallowing Guanabara Bay’s fetid water, as they have been advised. But there’s no getting around the city’s dirty air.

An air analysis by Reuters and Brazilian researchers from the University of São Paulo found high levels of fine particulate matter—PM2.5. The highest levels of this dangerous pollution were recorded at the Olympic stadium, which hit a peak of 65 PM2.5 micrograms per cubic meter of air volume during an hour-long test. (The WHO’s recommended limit, based on a 24-hour mean, is 25 micrograms per cubic meter.)

That’s going to take a toll on athletes’ performance. A study by University of Massachusetts Amherst professor Jamie Mullins found that increases in particulate matter hurt outcomes in a significant way, both statistically and competitively.

Rio’s environmental agency has downplayed the results of the independent test, telling Reuters that pollution can’t be measured in PMs alone. It also declined to share data on levels of larger particulate matter for the past couple of years. But published numbers for previous years showed that, despite promises to clean up ahead of the Olympics, Brazilian officials improved little years after winning its 2009 bid to host the games.

From 2010 to 2014, Rio averaged an annual level of 52 micrograms of coarser particulate matter (PM10) per cubic meter of air, reports Reuters. That’s more than twice the WHO’s recommended limit of 20 micrograms/cubic meter. (The organization notes that it has not identified any threshold low enough to not damage health.)

If those pollutions remain the same today, they would put Rio in second place for worst pollution ever by an Olympics host city. Beijing, which held the summer Olympics in 2008, gets the top honor, according to a 2009 study published in the journal Environmental Science and Technology.

In Rio, some 5,400 people died from air pollution in 2014, exceeding the city’s 3,117 murder victims last year, University of Sao Paulo pathologist Paulo Saldiva told Reuters.

Breathtaking 

Air-quality indices make pollution seem less bad than it is

SMOKING a whole packet of cigarettes in a day once or twice a year would certainly make someone feel ill, but probably would not kill him. Smoking even one cigarette every day for decades, though, might do so. That is the difference between acute and chronic exposure, and it is a difference most people understand. What they may not understand is that the same thing applies to air pollution.

On a day-to-day basis, the forecasts most cities offer turn red only when pollution levels rise to a point where they will cause immediate discomfort. That makes sense, for it lets people such as asthmatics take appropriate action. But it might also lead the unwary to assume, if most days in the place he inhabits are green, that the air he is breathing is basically safe. This may well not be the case. In London, for example, a study published last year by researchers at King’s College suggested air pollution shortens the city’s inhabitants’ lives by nine to 16 months.

To investigate the matter, The Economist crunched a year’s worth of data collected from May 2015 onwards in 15 big cities. They were gathered by Plume Labs, a firm based in Paris, which uses them to produce a commercial air-quality app. The three pollutants of most concern in rich countries are nitrogen dioxide (NO2, a brownish gas emitted by car exhausts, and particularly by diesels), ozone (a triatomic form of oxygen that irritates lungs) and soot-particles smaller than 2.5 microns across (which makes them tiny enough to get deep into the lungs). These pollutants can cause a variety of medical difficulties, including asthma, heart disease, lung cancer and stunted lung growth in children.

As the chart shows, levels of NO2 in London and Paris are routinely higher than World Health Organisation (WHO) guidelines about what constitutes a long-term hazard, known as the annual average limit—and that goes, too, for particulate matter. In London, during daytime, the concentration of NO2 exceeded the WHO’s limit by 41%, on average, over the 12 months examined. In Paris, where the national index said air quality was “good” or “very good” four days out of five, our analysis found that at least one of the three main pollutants exceeded the WHO’s limit at some point almost every day.

A further problem is that setting day-to-day limits is a local matter. So, not only do they rarely take long-term risk into account, they also vary from place to place. In Britain’s index a concentration of NO2 up to five times the WHO’s annual average limit counts as “low”. America is more conservative. It draws the line at two-and-a-half times the WHO limit. Worse, in some cases there is no pretence of objectivity. The website of Belgium’s BelATMO index, for example, warns that this is “a qualitative representation” of air quality that “has little scientific meaning”.

Cities also vary in the way they present pollution data. Most do so on a scale of ten or 100, which is then segmented into four to six bands labelled low, moderate and so on. Some places draw the line between “low” and “moderate” at the level at which pollution starts to cause immediate health effects, reserving the red band for smog that severely affects most people. Others divide the scale into equal chunks, each representing the same additional daily risk of dying or being admitted to hospital because of pollution.

Official indices also fail to capture patterns of variation within a day. These can be important—and people might be able to modify their behaviour if they understood them. Our analysis suggests, for example, that Parisians who head out for work at 9am and return at 6pm could reduce their average daily commuting intake of NO2 by 16% by travelling both ways an hour earlier. Going two hours earlier would cut the intake by 28%.

Weekly cycles also exist. Parents in Brussels and Paris might be wise to schedule their children’s indoor activities, such as swimming lessons, on Saturdays and outdoor stuff like football practice on Sundays. That is because, during daytime hours, the concentration of NO2 in those cities was, on average, about 20% lower on Sundays. In Amsterdam it was 16% lower. In all three places, fine-particle pollution also fell on Sundays, as did ozone in the summer months.

The best pollution advice of all to people in these cities, though, is: move to America. In New York, levels of NO2 were 20% below the WHO limit, and that is pretty typical of places in the United States, where diesels are less common than in Europe. As the inscription under the Statue of Liberty has it, “Give me your…huddled masses, yearning to breathe free.”

Major Study Links Air Pollution to Increased Mental Illness in Children

A ground-breaking new study from Sweden has highlighted a link between poor air quality and increased levels of mental illness in children. Though scientists have uncovered a growing body of evidence which had pointed to the link in the past, this study is the first to establish it outright.

Even more concerning, the study proves that mental illnesses are more likely to develop among young ones even in areas which suffer from fairly low but prolonged levels of air pollution.

What the study says

The study, first published in the science and health journal BMJ Open, is based upon the findings of a monitoring operation which kept track of pollution levels in areas affecting over half a million young Swedes aged 18 years or younger. This data was then cross-referenced with an analysis of the amount of medicines prescribed to the youngsters, including all types of medication from anti-psychotic drugs to sedatives.

What’s remarkable is that Sweden itself enjoys a good reputation when it comes to air quality, meaning that cities and countries with higher levels of pollution are likely at a higher risk of young ones developing mental health issues.

“The results can mean that a lower concentration of air pollution, first and foremost from traffic, may reduce psychiatric disorders in children and adolescents,” explained Anna Oudin, lead researcher on the study. “I would be worried myself if I lived in an area with high air pollution. In all the air pollution studies I have been involved in, the effects seem to be linear.”

A growing body of evidence

The Swedish paper might be the first to establish clear parallels between heightened pollution levels and an increase in mental illness, but it’s only the latest in a long line of research pointing to the harmful effects of poor air quality – especially with regard to children.

A Spanish study carried out last year monitored 2,715 children for one year to test how their cognitive and memory capabilities were affected over the course of 12 months. Those who lived in areas with higher air quality displayed greater percentages of improvement in both areas, drawing a parallel between pollution and intelligence.

Meanwhile, another year-long study was launched at approximately the same time, with the children from 1,200 families across Europe – and everything they came into contact during that time – monitored to determine how their exposure to pollution affected their development and health.

Bad news for the UK

The fact that the Swedish study uncovered these results even in areas with low air pollution levels which showed concentrations of nitrogen dioxide (NO2) below 15 micrograms per cubic metre (mcg/m3) means that young ones in Britain are almost definitely more at risk.

For reference, the recommended maximum level of NO2 (as advised by both the EU and the World Health Organisation) is 40mcg/m3. In certain parts of London, those levels can be many times higher, while earlier this year the Guardian reported that 433 schools in the capital were based in areas which exceeded legal limits for NO2.

With a concrete link between mental impairment and pollution now firmly established, it’s vital that the government and big business waste no time in improving air quality and transport-related pollution. The wellbeing of future generations depends upon it.

Timaru’s 21st high air pollution day 

Timaru saw its 21st high pollution day on Tuesday – one more than the number of breaches recorded by the same time last year and the eighth consecutive time air quality standards were breached this month.

On Tuesday the 24 hour average PM10 concentration was 56 micrograms of suspended particulate per cubic metre of air.

PM10 refers to particulate matter in the air that is smaller than 10 micrometres in diameter. A reading over 50 micrograms indicates “high” pollution under the national environmental standard.

Since 2006, between 21 and 36 days of high pollution were recorded at the Anzac Square site by this date.

So far this year, the Timaru station has recorded the most high pollution days of all centres monitored by the regional council.

Kaiapoi has had seven high pollution days, Rangiora has had six, Christchurch has had five, and Ashburton has had two. The Geraldine and Washdyke stations recorded one breach this year. Waimate has not had a high air pollution night so far this year.

All but two of Timaru’s breaches this year happened in June and July.

ECan’s Canterbury Air Regional Plan, which will become operative later this year, ultimately aims for Timaru to have fewer than three high pollution nights per year.

Timaru’s PM10 readings this year:

July 26: 56mcgs (11C, -3C)

July 22: 51mcgs (12C, -4C)

July 12: 69mcgs (10C, -4C)

July 11: 57mcgs (8C, 4C)

July 4: 60mcgs (19C, 2C)

July 3: 88mcgs (16C, 0C)

July 2: 62mcgs (11C, -5C)

July 1: 58mcgs (9C, -4C)

June 29: 57mcgs (12C, -1C)

June 22: 67mcgs (15C, 4C)

June 21: 56mcgs (10C, 5C)

June 18: 58mcgs (11C, 0C)

June 17: 74mcgs (17C, -3C)

June 16: 55mcgs (14C, -2C)

June 9: 70mcgs (16C, -2C)

June 8: 70mcgs (10C, -5C)

June 7: 73mcgs (11C, -3C)

June 6: 59mcgs (13C, -2C)

June 4: 51mcgs (15C, -2C)

May 2: 51mcgs

March 10: 55mcgs

Why it’s time Africa features in global plans to manage air pollution

Two years ago the World Health Organisation (WHO) identified air pollution as the world’s worst environmental health risk. It estimated that more than seven million people die prematurely due to air pollution every year. That is a staggering one in every eight deaths globally.

More than half of these deaths are as a result of household air pollution, almost all of which occurs in low- and middle-income countries. Africa has the highest number of these deaths after South East Asia and the Western Pacific. This is driven, in part, by the large percentage of the population using domestic solid fuel. Sub-Saharan African countries are estimated to have among the highest rates of deaths related to indoor air pollution from domestic fuel use.

Yet the WHO has not put in place an air quality programme for its sub-Saharan Africa region, even though these exist for other regions. The programmes include reviewing evidence on the health effects of air pollution, developing methods to quantify health risks and helping countries develop sustainable air quality policies.

It is not clear why there is no WHO air quality programme in sub-Saharan Africa. A possible explanation may be that environmental health risk factors have always been overshadowed by other risk factors like malnutrition, HIV, TB and malaria.

Africa’s acute problem

The 2016 update of the WHO Global Urban Ambient Air Pollution Database notes that people living in cities in low-income countries suffer the most from air pollution.

Onitsha, in Nigeria, has the highest calculated annual mean of PM10. PM10 are very small particles in the air and are so small that they can get into the lungs, potentially causing serious health problems. The country has a PM10 level of 594 micrograms per cubic metre, nearly 30 times higher than the WHO guideline of 20 micrograms per cubic metre. Although the calculation is based on limited data, there is no doubt that Nigeria has a serious problem.

Many areas of South Africa also have high levels of pollution. Particulate matter concentrations have been found to be up to 140% higher in township sites than in industrial sites. The average maximum PM10 value in these township sites on winter evenings is 200 micrograms per cubic metre.

A study conducted in Cape Town found that people faced a much higher risk of dying from heart and lung diseases than those living in developed countries. Outdoor air pollution levels in Cape Town are on average very similar to those of major European cities. The South African population may be more vulnerable due to high poverty and high rates of existing diseases such as HIV, TB, lung and heart disease.

Global action to improve air quality

Soon after the WHO released its report in 2014 the United Nations Environment Programme (UNEP) adopted a resolution to promote air quality. This urged leaders to take action to improve air quality with the support of the United Nations body. It also developed an implementation plan that included activities focused on:

  1. Creating awareness;

    2. on climate, energy and health being formed in South Africa under the umbrella of the Public Health Association of South Africa.

    African scientists can also work to develop local regional working groups focused on air quality under initiatives like Future Earth.

    Ensuring all players work together towards more visibility, collaboration and support for air quality in Africa is crucial.

Hot temperatures provoked air pollution alert in Maine over the weekend

The Maine Department of Environmental Protection (DEP) issued on Friday an air quality alert due to unhealthy ground-level ozone concentrations in the air along the Maine Coast from Kittery to Acadia National Park.

The federal Environmental Protection Agency announced Friday at 11:00 a.m. that parts of New England will suffer air pollution in coastal Connecticut, all Rhode Island, southeastern Massachusetts and southern and central coastal Maine.

The Federal air quality standard for ozone was surpassed and follows a shift in the weather pattern according to the National Weather Service. The change brings hot, and humid air from the south and temperature was expected to reach the 90 degrees on Friday with higher moist levels.

Ground-level ozone is a byproduct of emissions from factories, power plants and vehicles exhaust from their motors. It includes lawn equipment, household paints, stains, and solvents.

To help reduce emissions, the Environmental Protection Agency recommended people to use public transportation, carpool and limit the use of electricity on Friday. These actions will avoid increasing the levels of ground ozone.

The Maine DEP warned people that ground-level ozone could cause a lung function reduction and irritation, for everyone, especially for children and people with respiratory diseases such as asthma, bronchitis or Chronic Obstructive Pulmonary Disease (COPD). A person with reduced lung function and irritation will experience shortness of breath, coughing, throat irritation, and it is possible to feel an uncomfortable sensation in the chest.

To avoid health problems, the Department urged people to stay indoors and avoid if possible working is exercising outdoors.

The DEP recommends consulting Maine CDC website for information on the health impacts of the extreme heat, to take appropriate actions. For those people suffering asthma, the Maine CDC Asthma Prevention and Control Program has information on the disease on its website. The EPA’s website also has information about what could trigger asthma and teaches on asthma management.

Ground-level ozone: very present on summer days

Ground-level ozone has nothing to do with the protective role that has layered in the atmosphere, also called ozone. Ozone Aware explains that ground-level ozone is a harmful air pollutant that forms when emissions from everyday items combine with other pollutants when the weather is hot and temperatures approach 80 to 90 degrees.

Prolonged exposure can cause a reduced resistance to lung infections and colds and can also trigger pre-existing conditions in individuals with asthma, bronchitis, and COPD.

The DEP asks people to stay alert to new air pollution alerts.

Mayor of London offers £11m to tackle air pollution

Mayor of London Sadiq Khan is offering funding worth £11 million to tackle air pollution in the capital.

Eight of the most polluted boroughs will receive a share of the fund to implement measures to fight toxic air quality and filthy emissions fumes.

In addition, five ‘Low Emission Neighbourhoods’ will be set up across the eight boroughs, with pollution-busting measures including strict new penalties for the dirtiest vehicles, car-free days, green taxi ranks for zero emission-capable cabs and parking reserved for the cleanest vehicles.

Those hotspots will be in the boroughs of Westminster, Hackney, Greenwich, City of London and Redbridge and Newham.

The funding expands on former Mayor Boris Johnson’s Low-Emission Neighbourhoods initiative, which provided £2 million of funding to two London boroughs to test innovative measures to improve air pollution.

Mr Khan said: “Make no mistake: London is in the midst of an air quality crisis. Air pollution is permanently affecting children’s lung development and nearly 10,000 Londoners are dying early every year due to the long-term exposure of London’s dirty air. We need urgent and bold action and this includes targeted local initiatives to tackle some of the worst pollution hotspots in London.

“I’m also calling on government ministers to put in place incentives for people to switch to low emission vehicles as well as providing London with additional powers and funding to help tackle this public health crisis.”

Earlier this month the mayor proposed plans to charge £10 for the most polluting vehicles entering London.
