In terms of health impacts, the air quality in Beijing and other parts of northeast China is off the charts. On Monday, the air quality index measured at the U.S. Embassy in Beijing reached a staggering 611 for small particulate matter. In the U.S., the EPA considers an index over 100 to be unhealthy. At an index over 300, the air quality “would trigger a heath warning of emergency conditions,” reads airnow.gov. “The entire population is more likely to be affected.”
Particle pollution of this tiny size, just 2.5 micrometers, is incredibly hazardous to health, and even more so at these extraordinary levels. According to the EPA, particles smaller than 10 micrometers are the most dangerous to health because they can embed deep in the lungs. Some of the particles are even small enough to enter the bloodstream directly through the lungs.
Pollution this extreme can cause premature death, aggravated asthma, irregular heartbeats and decreased lung function. Though the young, elderly and sick are particularly vulnerable to air pollution, levels this high effect even the healthiest of people.
An orange air quality alert was issued on Sunday, which required industry to cut production. A windy area of low pressure is forecast to sweep over northeast China on Tuesday and Wednesday which should help to alleviate the pollution concerns in Beijing.
