Health effects to Air Pollution

What health effects are linked to air pollution? Over the past 30 years, researchers have unearthed a wide array of health effects which are believed to be associated with air pollution exposure. Among them are respiratory diseases (including asthma and changes in lung function), cardiovascular diseases, adverse pregnancy outcomes (such as preterm birth), and even death. In 2013, the World Health Organization concluded that outdoor air pollution is carcinogen to humans. How can I reduce my risk for air pollution [...]

Beijing turns to railway for urban freight transport

Beijing is using railway lines for freight transport in urban areas to reduce truck emissions and ease traffic. A 50-car train carrying 3,200 tonnes of gravel arrived at a freight station in Dahongmen in Fengtai District on June 2018, marking inauguration of the project. The gravel, delivered from Tangshan City in neighboring Hebei Province, was sent to a contractor as construction material, said Zhang Jinchao, deputy general manager with the Jingtie Logistics, an affiliated company of China Railway Beijing Group.

Harvard physician extols health benefits of going green — for our bodies and our planet

There was an irony to Aaron Bernstein’s getting stuck in traffic recently. The Harvard Medical School professor and physician at Boston Children’s Hospital was on his way to Allston to give a talk about the health benefits of going green. “As a routine bicyclist, I rarely drive anywhere in Boston, and I was reminded on my drive here why. It took me an aggravating 45 minutes to get a mile and a half,” he (eventually) told the audience at the [...]

Temperatures to rise along with ozone pollution

Hot weather and ozone pollution are making a comeback, weather authorities say. High temperature hit more than 33 degrees. Sunny skies are predicted for both days. It will be cloudy to overcast for the rest of the week, but the high will hover around 30 degrees, according to the Shanghai Meteorological Bureau. Shanghai saw slight to moderate air pollution, with ozone being the major pollutant. The index will read between 120 and 140 this afternoon, indicating light air pollution. It [...]

Outdoor and indoor Air Pollution

Air pollution is a mixture of natural and man-made substances in the air we breathe. It is typically separated into two categories: outdoor air pollution and indoor air pollution. Outdoor air pollution involves exposures that take place outside of the built environment. Examples include: Fine particles produced by the burning of fossil fuels (i.e. the coal and petroleum used in energy production) Noxious gases (sulfur dioxide, nitrogen oxides, carbon monoxide, chemical vapors, etc.) Ground-level ozone (a reactive form of oxygen [...]

China tests giant air cleaner to combat smog

A 60-metre-high chimney stands among a sea of high-rise buildings in one of China’s most polluted cities. But instead of adding to Xian’s smog, this chimney is helping to clear the air. The outdoor air-purifying system, powered by the Sun, filters out noxious particles and billows clean air into the skies. Chinese scientists who designed the prototype say that the system could significantly cut pollution in urban areas in China and elsewhere. The technology has excited and intrigued researchers — [...]

Air pollution battlefield brings investment opportunities

China's efforts to control air pollution will provide a new impetus for economic growth, with investment opportunities of 20 trillion yuan ($3.2 trillion) in the coming 12 years, according to a report by an antipollution industry group. The market potential lies in six major sectors, including coal pollution control, reduction of volatile organic compound emissions and environmental monitoring. The report, titled China's Clean Air Market Outlook 2030, was published on Tuesday by the Bluetech Clean Air Alliance, an industry alliance [...]

By 2023 will have city constructed entirely from bamboo

Imagine a city rising from a lush bamboo forest, but this city uses no concrete and no steel; it doesn’t stick out of the forest, so much as blend in. This is the vision presented by penda, a Chinese and Austrian design firm, at Beijing Design Week this year. By 2023, penda claims, a city housing 20,000 people could be built entirely from their modular bamboo construction system, free to grow in every direction as the need arises. The system [...]

Beijing’s air quality improves in first four months of 2018

Beijing saw better air quality and more "good air" days in the first four months of this year, the Beijing Municipal Environmental Protection Bureau announced on Monday. Average density of PM2.5 in Beijing stayed at 59 micrograms per cubic meter of air in the four months, down 22.4 percent year on year, the bureau said. The capital saw 77 good air days from January to April, four days more than the same period last year. The number of heavy pollution [...]

China enlists 60,000 soldiers to plant trees in war against air pollution

China is under attack on its own soil. And just as most countries with a large armed force would do, the country is deploying troops — over 60,000 members of the People’s Liberation Army — with no delay. The invading force is insidious and can’t be dealt with using traditional military tactics — the raw manpower is needed but none of the standard maneuvers of warfare apply. And this is why China is arming its soldiers with two of the [...]

New round of pollution inspections begins

The country's top environmental watchdog will dispatch about 18,000 law enforcement officers to conduct air pollution control inspections in three key areas started on last January. Last year, the Ministry of Environmental Protection-which has since been incorporated into the Ministry of Ecology and Environment-sent 5,600 law enforcement officers to 28 major cities in the Beijing-Tianjin-Hebei region to inspect air pollution control work. This year, the inspection, dubbed "Blue Sky Protection Campaign", will be extended to the Yangtze River Delta and [...]

Air Pollution and Plants

Air pollution, release into the atmosphere of various gases, finely divided solids, or finely dispersed liquid aerosols at rates that exceed the natural capacity of the environment to dissipate and dilute or absorb them. These substances may reach concentrations in the air that cause undesirable health, economic, or aesthetic effects. Plants occur over Earth’s surface in well-defined patterns that are closely correlated with both climate and the history of the planet. Forests are the most important of these natural communities [...]

China to Standardize EV Technology Nationally

The popularity of electric vehicles is at an all-time high in China. Last year, the total sales of electric and plug-in hybrid vehicles accounted for four times as much as that of those in the United States. It is expected that the margin will only grow wider this year. This shift in trend can be attributed to the fact that over the course of the next two decades, China is planning on moving away from gas-powered vehicles completely. As China is [...]

China Plans To Build Nearly 300 New Eco-Cities

China is not exactly known for its eco-conscious ethos. In fact, it's one of the world's biggest polluters, with limited environmental regulation stopping the flow of toxins into the environment. Even the regulations that do exist are often ignored by large companies – some 70 percent of businesses examined by environmental inspectors failed to meet environmental standards for controlling air pollution, according to a state news agency report. Now, according to the Chinese Ministry of Health, industrial pollution has made [...]

Little Things Matter: The Deadly Impact of Airborne Particles

The link between air pollution and death was established in a series of disasters around the world. About 15% of all deaths in the world are from ischemic heart disease; that’s when your heart literally suffocates. As the levels of air pollution increase, the percent of deaths from heart disease rises sharply – even at levels below the World Health Organization guidelines. If we decreased particles around the world to levels found in Vancouver, we could prevent 3 million excess [...]

Air pollution – The Silent Killer

World Health Organization estimates that around 90% of people worldwide breathe polluted air. Over the past 6 years, ambient air pollution levels have remained high and approximatively stable, with declining concentrations in some part of Europe and in the Americas. The highest ambient air pollution levels are in the Eastern Mediterranean Region and in South-East Asia, with annual mean levels often exceeding more than 5 times WHO limits, followed by low and middle-income cities in Africa and the Western Pacific. [...]

Countries taking action

More than 4300 cities in 108 countries are now included in WHO’s ambient air quality database, making this the world’s most comprehensive database on ambient air pollution. Since 2016, more than 1000 additional cities have been added to WHO’s database which shows that more countries are measuring and taking action to reduce air pollution than ever before. The database collects annual mean concentrations of fine particulate matter (PM10 and PM2.5). PM2.5 includes pollutants, such as sulfate, nitrates and black carbon, which pose [...]

7 million deaths every year

WHO (World Health Organization) estimates that around 7 million people die every year from exposure to fine particles in polluted air that penetrate deep into the lungs and cardiovascular system, causing diseases including stroke, heart disease, lung cancer, chronic obstructive pulmonary diseases and respiratory infections, including pneumonia. Ambient air pollution alone caused some 4.2 million deaths in 2016, while household air pollution from cooking with polluting fuels and technologies caused an estimated 3.8 million deaths in the same period. More [...]

9 out of 10 people worldwide breathe polluted air

Air pollution levels remain dangerously high in many parts of the world. New data from WHO shows that 9 out of 10 people breathe air containing high levels of pollutants. WHO estimates that around 7 million people die every year caused by ambient (outdoor) and household air pollution, from heart disease, stroke, lung cancer and respiratory diseases like pneumonia due to exposure to polluted air. “Air pollution threatens us all, but the poorest and most marginalized people bear the brunt [...]
