PM2.5 measurements refer to tiny particles less than 2.5 micrometers in size or approximately 1/30th of the average of breathable air for humans. Tiny as they are, these particles can easily pass through the air sacs and penetrate deep into the lungs. As a result, people who breathe in these particles will likely develop respiratory illnesses. The more particles a person breath in,pastry chef weakness Strengths and Weaknesses Discuss Cooking Cooking Forums. the more severe the respiratory ailment he can get later on.

Smog has reached alarming levels in Beijing and much of northern China,aduedu869.typepad.com. forcing parents to keep their children inside and sending many to the hospital.

At the time the image was captured, NASA reports, the air quality index in Beijing was 341. Levels above 300 are considered Hazardous. The embassy is posting real-time updates of the air quality index on its website and also on the BeijingAir Twitter feed.

In the winter, we have to burn more coal to get heating, says Zhou Rong of Greenpeace. She says around 50 percent of Beijings air pollution is historically due to coal-fired power stations. Another reason is the weather pattern makes the whole atmosphere very, very stable, and so all the air pBeijings Pollution Seen From Space In Before And After Photos satellite viewollution accumulates down to the ground, so we are getting higher and higher air pollution.

The brightest areas tend to be clouds or fog, which have a tinge of gray or yellow from the air pollution. Other cloud-free areas have a pall of gray and brown smog that mostly blots out the cities below. In areas where the ground is visible, some of the landscape is covered with lingering snow from storms in recent weeks.
NASA explains what seen on Mondays image:
Pollution around Beijing has been stifling for the past few days. NASA has released a pair of satellite images, showing the extent of the smog from space and how the air has changed in the past couple weeks.
/But what does it look like from space?
China is choking on its own breakneck development, with thousands of new cars taking to the road every day. This year, the pollution has been exacerbated by weather patterns, combined with an unusually cold spell.
NASAs Earth Observatory released a pair of satellite images today that show Beijing and the surrounding areas on Monday and 11 days earlier, on Jan. 3.
This combination of photos shows (left) the Beijing skyline during severe pollution Monday, and the same view (right) taken during clear weather on Feb. 4, 2012.
