Map of global air-particulate pollution  (Source: Aaron van Donkelaar, Dalhousie University)
Industrial sector of this region has the highest concentration of particulates

Canadian scientists have developed a map of global air-particulate pollution using National Aeronautics and Space Administration satellite data, and it shows that China's air quality is very poor compared to the rest of the world. 

Aaron van Donkelaar and Randall Martin from Dalhousie University in Halifax, Canada created the map using satellite data because they believed ground-based detection would be "spotty" in areas or nonexistent. The data used for the map is from 2001 to 2006. 

The map of global air-particulate pollution shows fine particulate matter density worldwide through color-coding, where white and dark blue areas have the lowest concentration of particulates and dark red areas have the highest concentration of particulates. The reddest part of the entire map is Eastern China's industrial area.

Despite the fact that the data used for the map is from 2001 to 2006, The Wall Street Journal noted in July that China's air quality is getting worse, and has not improved since the time period of this data.

In fact, more recent studies, such as the research conducted by a team of scientists who studied air pollution along the Yangtze River Delta in China, proves that China's air quality is only getting worse. This particular study concluded that the Yangtze River Delta is one of the most densely populated areas in the world and the "fastest growing economic development region in China." The area has seen drastic increases in atmospheric emissions and energy consumption, which led the team of researchers to use the Community Multiscale Air Quality model along with an emission inventory to measure baseline concentrations in order to calculate health risks and construct control strategies.

Many health issues arise from poor air quality because fine particulates are capable of passing the body's cilia defenses and penetrating the lungs and blood. Bronchitis, cardiovascular disease and asthma are a few of the illnesses that can come from poor air quality. Through both of these studies, researchers can better understand what China is up against and can develop ways to counter it, saving hundreds of millions of people who live in this area from chronic disease.

This study was published in Environmental Health Perspectives.

Makes you happy about the "sky is falling" campaign over pollution in the US when a big portion of our jobs are being shipped to China to make all these "green" products. So now they can get cheap labor and still mark up the retail price since marketing came up with a really snazzy "Enviro-friendly" logo to slap on it. The Italian Mafia must be envious of the world-wide racket being run by big business and governments. Or banks loansharking the peasants money to buy the now unfordable products.

Funny how the government has no problem mandating things deemed "environmentally responsible" when it cuts into the low/middle-classes dollar, but pretend to not see any problems with companies sending work over to China and then importing it back into the country. Surely they did a multi-million dollar investigation that buying more equipment for reducing/recycling greenhouse gases costs more money than not buying it. I guess some arbitrary government commitee didn't get it's funding to study that building stuff in China with sub-par working and living conditions, a forced monetary value, and no environmental policy and shipping it half way around the world still pollutes - so much for altruism. They might have better luck once they conclude their current study on "WTF are we going to do when the tax payers have no money left to tax?" Bottom line, cutting into big business' dollar means cutting into campaign funds.
