Fireoworks Led to 25 times the Normal Pollution Levels in Beijing
Fireworks set off during Chinese New Year
celebrations on Thursday increased Beijing's air pollution index and the
concentration of PM2.5 - considered to be extremely harmful to health -
multiplied 25 times in a matter of seven hours, U.S. diplomatic
authorities said. To welcome the Year of the Goat
and bid adieu to the Year of the Horse, Beijing residents exploded
firecrackers, which according to Chinese tradition, is said to keep bad
luck away. As a result, the concentration of
PM2.5 levels rose from 16 micrograms per cubic meter at 6 p.m. local
time Wednesday to 407 micrograms per cubic meter at 1 a.m. Thursday in
Beijing, the U.S. embassy in China said on its Twitter account.PM2.5
particles, with a diameter smaller than 2.5 microns (1,000 times
smaller than 2.5 millimeters) are considered to be extremely harmful as
they can directly enter the lungs.
According to the World Health Organization, the recommended level for PM2.5 is no more than 25 micrograms per cubic meter within the 24-hour time frame. Beijing woke up Thursday to thick smog covering the skies, which seemed to undo the recent drop in air pollution caused by closing of factories and lesser traffic on the roads during the holiday. Firecrackers and fireworks displays lit up the occasion, despite restrictive measures adopted by the Chinese authorities.
A total of 138 cities adopted prohibitory measures and another 536 restricted firecrackers in order to have clearer skies during the festive season, according to the Chinese Ministry of Public Security. During recent weeks, the authorities also made several appeals to the people to limit the use of firecrackers, keeping in mind their effects on air quality. Forecasts of less wind in several regions of the country, especially in the center, coupled with the incessant use of firecrackers, are expected to aggravate the concentration of pollutants in the sky even further.

US Embassies Monitoring Air Quality in Multiple Countries
In 2008, American diplomats in Beijing quietly installed an
electronic monitor outside the U.S. Embassy to test pollution levels in
the Chinese capital’s famously sooty air. The results, posted daily on
the Internet, were mainly intended for U.S citizens and visitors, but
soon ordinary Chinese were logging in for reliable information about
health threats in the air they breathed. Chinese officials complained, but the daily reports from the embassy’s monitor added
to the pressure that eventually led China to take dramatic steps to
reduce smog. It worked so well, in fact, that the Obama administration
has now decided on a major expansion — to U.S. diplomatic missions all
around the world.
In a joint announcement on Wednesday, Secretary of State John F. Kerry and EPA Administrator Gina McCarthy unveiled plans to place air-quality monitors outside embassies in numerous foreign cities, starting with diplomatic posts in India and then moving to Vietnam, Mongolia and other countries.

Agencies Refusing to Share Monitoring Data in Delhi

Real time AQI in Delhi
The plan to issue an advisory about worst polluted areas was initiated during Commonwealth Games 2010 but it had remained on paper. A senior environment ministry official blamed monitoring agencies working in silos for the failure. “One agency was not willing to share its data with another,” he said. Since September 2013, the Delhi Pollution Control Committee having six real-time air pollution monitoring stations has not shared its pollution data with the Central Pollution Control Board (CPCB), mandated to issue the advisory. Parallel to this, the Ministry of Earth Sciences also set up its own 10 pollution monitoring stations in the capital during the games but refused to collaborate with CPCB or DPCC.

“You need will and it can happen,” Anumita Roy Chaudhary of Centre for Science and Environment said, recalling how Supreme Court pushed Delhi government in 2000 to introduce Compressed Natural Gas (CNG) as alternate fuel and Delhi’s pollution dipped by almost 50% in a few years. This time the measures needed may be harsher as PM 2.5 microns that enter deep inside one’s lungs and can trigger heart attack was 20 times higher than the safe level prescribed by the government in Delhi.

Capping Coal in China Will Drop Carbon and Particulate Pollution
China's power sector accounts for almost a quarter of the world's
total coal consumption, or as much as all the OECD countries consume
together. Controlling China's coal consumption - as Beijing has vowed in
its most recent Energy Development Strategy Action Plan
- requires the power sector to take significant measures to optimize
its energy sources, using less dirty coal and more clean alternatives. Conducted as part of NRDC's China coal cap project, a new study
by North China Electric Power University led by Assistant Professor
Yuan Jiahai, lays out a pathway for capping coal consumption in which
China's power sector can not only reduce its emission of dust, SO2,
NOx, and other air pollutants but, more critically, contribute to
economic and social gains through decreased coal power investments and
fuel costs and increased health benefits.
Such a pathway adopts aggressive targets in energy efficiency and renewable energy deployment and integration, as well as end-of-pipe pollution control measures. For end-use energy efficiency, the study calculated the energy saving potential of using more efficient lighting, generators, transformers, speed governors, home appliances, and ground source heat pumps at a total of 701 TWh in 2020 - an amount that would take the Three Gorges Dam over seven years to generate - and even larger in the future.
When existing air pollution control regulations are effectively implemented - no new regulations required - such a coal cap scenario can significantly reduce dust, SO2, and NOx emitted by the country's coal-fired power fleet (see graph below). Furthermore, the coal cap scenario also projects lower CO2 emissions from the power sector (nearly 900 million tons lower compared to the reference scenario peak), and lower stress on water resources in China's coal-producing western regions: compared with the reference scenario, water consumption of six major western coal bases in the coal cap scenario is 57 million tons less in 2020, and 606 million tons less in 2030.

57% of Carbon Pollution in Hyderabad Comes from Vehicle Pollution
A recent report that conferred upon Hyderabad the dubious distinction of recording the highest level of vehicular pollution in the country has left city environmentalists alarmed. The study, conducted by the Indian Institute of Science (IISC), Bangalore, stated that the contribution of vehicular pollution to the city's carbon content is over 57% -- higher than the percentage registered in other major cities as Bangalore, Mumbai and Chennai. This, despite Hyderabad having a significantly lower number of vehicles compared to the other metro cities. Experts have squarely blamed the Pollution Control Board (PCB) for failing to nip the problem in the bud. They rue how the department, despite being aware of widespread use of adulterated fuel and the presence of a large number of old vehicles on the roads, conducts no checks to punish offenders.
"We don't need a report to tell us that vehicular pollution has increased in the city. It is evident in our daily lives. What is terrifying is that the authorities refuse to act on these long-standing issues," lamented M Padmanabha Reddy, a retired Indian Forest Service officer, deploring the PCB's lackadaisical approach to such serious issues. PCB officials, however, refused to take responsibility. In fact, its officials conveniently blamed the ongoing Metro rail project work for rising air pollution. Tired of this blame-game, environmentalists are now advocating the need for increased green cover.

Delhi’s Air Is Often More Polluted Than Beijing’s
The levels of harmful fine particulate matter,
called PM2.5, are significantly higher in Delhi during the winter months
than they are in Beijing. Over the past two years, average
concentrations in Delhi have been about 45 percent higher.
Beijing has more than 30 government monitors tracking its air quality, although the historical data is not widely available. Delhi has just four, in addition to one at the U.S. embassy. “Delhi doesn’t have nearly enough, said Joshua Apte, an assistant professor at the University Texas at Austin, “and it’s still the best off in the country.”

Evolution of On-road Vehicle Exhaust Emissions in Delhi - A Study from 1990 to 2030
For a 40-year horizon (1990–2030), on-road vehicle exhaust emissions
were evaluated, retrospectively and prospectively, for the largest urban
agglomeration in India – the Greater Delhi region with a combined
population of 22 million in 2011 (Delhi along with Ghaziabad, Noida,
Greater Noida, Faridabad and Gurgaon). Emissions of particulate matter,
sulfur dioxide, carbon monoxide and volatile organic compounds (VOCs)
reached their peak during late 1990s through early 2000s after which
they reduced significantly through year 2012. On the other hand,
nitrogen oxides (NOx) and carbon dioxide show an increasing
trend.
Access to the full report @ Atmospheric Environment
The most reduction in emissions between 1998 and 2012 occurred as a result of implementation of four sets of vehicular emission standards, removal of lead, reduction of sulfur content, mandatory retirement of older commercial vehicles, and conversion of diesel and petrol run public transport vehicles to compressed natural gas. In addition, changes in the vehicular technology have also contributed to controlling emissions especially in case of auto-rickshaws and motorized two-wheelers, which changed from two-stroke to four-stroke.
The rising trend of NOx along with the presence of VOCs indicates increasing tendency to form ground-level ozone and as a result, smog in the region. We predict that the current regime of vehicle technology, fuel standards, and high growth rate of private vehicles, is likely to nullify all the past emission reductions by the end of 2020s.

Air Pollution Linked to 553 Annual Deaths Across Northern Ireland
A Belfast medical expert has called on health organisations to phase out their investment in the fossil fuel industry as it emerged that such air pollution is also said to be responsible for more than 140 deaths across the city. Dr Gary McFarlane, director of the Chartered Institute for Environmental Health, joined medical experts from across the UK in calling on health organisations to divest in the industry, as they have already done with tobacco.
Dr McFarlane said: "The science is telling us very clearly that continued reliance on fossil fuels is not only unsustainable but will have significant health implications across the globe.

Shanghai to Spend US$16 billion on Anti-Pollution Campaign
SHANGHAI will spend 100 billion yuan (US$16.13
billion) in the next three years on more than 200 projects in an effort
to rid the city of pollution, authorities said yesterday. The funds will be spent on 220 projects in eight areas of concern,
namely, water, air, soil, waste, industry, agriculture, ecology and
circular economy, said Zhang Quan, director of the Shanghai
Environmental Protection Bureau. The major concerns are serious nitrogen and phosphorus pollution in
water, high level of PM2.5 pollutant particles in the air, chemical and
oil fumes from restaurants, Zhang said.
Article @ Shanghai Daily
The aim is to significantly cut the number of heavy pollution days and reduce the PM2.5 density to 48 micrograms per cubic meter by the end of 2017. The World Health Organization says a “safe” PM2.5 concentration is 25. The city’s overall air quality improved last year from 2013 thanks to the absence of extreme weather and putting in place anti-air pollution measures like the use of cleaner energy sources. The average PM2.5 density was 52 last year, down 16.1 percent from 2013.
Also on the agenda are 17 sewage treatment plans. The Bailonggang factory will be renovated, and three sewage treatment factories will be constructed in areas such as Nanxiang and Hongqiao.
By 2017, all big and medium restaurants will be installed with highly efficient oil smoke purifying facilities, and about 300,000 heavily polluting vehicles will be eliminated from the street. A total of 171,600 heavily polluting vehicles were eliminated from the city roads last year. This year, more than 90,000 polluting vehicles will be eliminated while 1,100 boilers at small and medium plants will be replaced. Over the past three years, the discharge of four major pollutants — chemical oxygen, ammonia nitrogen (NH3-N), sulfur dioxide and nitrogen oxide had also dropped substantially, Zhang said. Enterprises were fined more than 100 million yuan last year for breaking the city’s air pollution regulations. Some 3,180 hectares of green space have been added in the past three years with the total forest coverage touching 14 percent at the end of last year. About 2.8 million households had been included in the garbage sorting plan.
Its per capita garbage treatment volume of household garbage was 0.66 kilograms daily last year, compared with 0.82 kilograms per day in 2010, according to the Shanghai Greenery and Public Sanitation Bureau. But the awareness of garbage sorting among the public was still weak.

Why is India so Hungry for Coal (CNN)
Holding onto the rails of a cage, we descend lower and lower into the coal mine. It is pitch dark, hot and humid. Every now and then a spray of water drizzles on us. The two-minute ride down seems much longer than that. Once we reach the bottom of the shaft, we begin a 3.5 kilometer walk underground to the site where miners are excavating coal. For almost an hour, we trudge through the slush, the light from our safety helmets the only illumination underground. Our protective clothes and faces quickly develop a black layer of coal dust. Coal is a polluting fossil fuel, which currently powers more than 60% of India. The government produced 462 million tonnes of it last year and is targeting a billion tonnes by 2019. Typically, the coal that burns in power plants across India is of poor quality, therefore more harmful. India is already the world's third highest emitter of greenhouse gases.

US Embassy in Delhi Bought 1800 Air Purifiers in January
Prior to the recent visit of US President Barrack Obama, the
American embassy in Delhi purchased over 1,800 high-performance portable
Blueair indoor air purifiers to protect employees at the embassy and
other locations. In the national capital, the US Embassy, which monitors air quality
around the embassy buildings and issues daily updates, became so
concerned about the high levels of air pollution that it ordered a
large number of indoor air purifiers from Blueair and handed these over
to its staff. Article @ Financial Express
Air Quality Report
Commenting on the decision by the US Embassy to buy such a large number of Blueair indoor air purifiers, the company’s founder and CEO Bengt Rittri, said: “The order confirms Blueair’s position as the ‘air purifier of choice’ when it comes to protecting U.S. government employees and their families from health and wellbeing threats posed by polluted indoor air”. On Tuesday this week, the American embassy’s monitoring station recorded an Air Quality Index reading of 222, a level the U.S. Environmental Protection Agency (EPA) describes as ‘very unhealthy’. The EPA says such air pollution levels can cause “significant aggravation of heart or lung disease and… a significant increase in respiratory effects in the general population.”
A vast array of international institutions, government agencies and corporations already use Blueair air purifiers, which are equipped with a Smokestop filter as “the best at cleaning air as quickly as possible” after an exhaustive, independent test of top air purifiers models. “Blueair air purifier’s may also help protect users against virus’s such as H1N1 (Swine Flu) because they are designed to trap polluting airborne particles such as PM2.5 dust, viruses, bacteria, asthma triggers and other contaminants such as VOC’s,” says Vijay Kannan, head of Blueair India, a wholly-owned subsidiary of Sweden’s Blueair AB. He noted that Sweden’s Institute for Infectious Disease Control (SIIDC) has used Blueair air purifiers for many years to protect their staff from harmful airborne particles.
