See How the World’s Most Polluted Air Compares With Your City’s

Outdoor particulate pollution was responsible for an estimated 4.2 million deaths worldwide in 2015, with a majority concentrated in east and south Asia.

This fine pollution mainly comes from burning things: Coal in power plants, gasoline in cars, chemicals in industrial processes, or woody materials and whatever else ignites during wildfires.

The particles are too small for the eye to see — each about 35 times smaller than a grain of fine beach sand — but in high concentrations they cast a haze in the sky.

This microscopic pollution, named because each particle is smaller than 2.5 micrometers across, has also been linked to developmental problems in children and cognitive impairment in the elderly, as well as premature labor and low birth weights.

In the United States, which has some of the cleanest air in the world, fine particulate matter still contributed to 88,000 premature deaths in 2015 — making this pollution more deadly than both diabetes and the flu.

In San Francisco, nearly 200 miles south of Paradise, fine particulate pollution reached nearly 200 micrograms per cubic meter at the worst hour, according to Berkeley Earth, a nonprofit research group that aggregates data from air-quality monitoring sites.

But fire hazards are also increasing because of greater development in areas abutting wildlands, the over-suppression of natural wildfires, and aging electrical infrastructure (broken power lines were identified as the cause of California’s deadly Camp Fire).

Average air pollution in both Seattle and the Bay Area remains relatively low outside of large fire events, but even periodic exposure to such high levels of PM2.5 pollution can have lasting health consequences.

In an effort to clear the hazy skies, the government temporarily halted all construction projects and restricted the number of cars on the road, requiring vehicles with odd- and even-numbered license plates to drive on alternate days.

Starting in late October and early November, smoke from upwind agricultural burning combines with Delhi’s year-round urban pollution — a toxic mix of vehicle exhaust, industrial emissions and construction dust — to create an eye-watering smog.

Last week, India’s Supreme Court criticized state governments for repeatedly failing to resolve the regional air pollution crisis and for ignoring the court’s previous orders to limit agricultural burning.

Calling clean air and water a constitutional right, the court said the local governments should pay their citizens compensation if they fail to clean up the environment and gave authorities six weeks to respond.

“We will resolutely declare war against pollution as we declared war against poverty,” Premier Li Keqiang announced in front of 3,000 delegates at the National People’s Congress in an address broadcast on state television.

Air Pollution in India and China: Out of the Smog?

These measures and calls for polluters' responsibility have not had much effect – largely because there has been an increase in slash-and-burn cultivation in Punjab.

A bar where oxygen can be filled with compressed air cylinders has even opened – one can 'consume' for a quarter of an hour at a rate ranging from 299 (off-peak) to 499 (peak) rupees.

In Beijing and Hebei province, which concentrates heavy industries, including nearly 25% of national steel production, the concentration of PM 2.5 particles exceeded 1000 μg/m3 on several occasions, and the average stagnated at around 500 μg/m3, a level at which the health effects on the most vulnerable are immediate.

Available on the Embassy's Twitter account and via smartphone applications, the measures put strong pressure on the Chinese authorities because of the international media coverage they generated, but also because of the local attention they caught from residents seeking information.

Once the problem had been classified as a national emergency and Premier Wen Jiabao had announced in March 2014 a 'war on pollution', the Chinese State redoubled its efforts, using all of its strike force, its efficiency and its ability to assume severe collateral damage on special interests, all the while seeking a balance between air quality and industrial interests.

The Chinese Market for Indoor Air Quality

NEW YORK, Dec. 2, 2019 /PRNewswire/ -- Report Scope: This report is confined to covering IAQ issues at residential homes, commercial buildings and light industrial properties, schools and hospitals in China.It does not discuss IAQ issues relevant to heavy industry and manufacturing environments, nor does it cover IAQ issues, practices, equipment and regulations concerning confined spaces or aircraft.

Report Includes: - 97 tables - An overview of Chinese market of indoor air quality (IAQ) - Coverage of important products, services, manufacturers, and service providers related to the industry - Information on production technologies and factors influencing demands for IAQ products - Discussion of recent advances in technologies and products within the industry - Insight into regulatory and environmental developments - Profiles of key players in the market, including 3M, Panasonic Corporation of China, Philips (China) Investment Co.

This report forecasts that the Chinese IAQ market will grow at a compound annual growth rate (CAGR) of REDACTED% from 2019 to 2024, reaching $REDACTED billion by 2024, as most of the low-quality air cleaners exited the market in 2018 and 2019, and the whole air cleaner market will return stable growth, although still at a slower rate than from 2011 .and 2016Read the full report: About Reportlinker ReportLinker is an award-winning market research solution.
