China’s air pollution ‘Similar to Nuclear Winter’

CHINA Air POLLUTIONChina has suffered from increasingly bad levels of air pollution, resulting in both health and environment fears. However, scientists have said that the air quality in the country is now so bad that conditions are similar to those that would be experienced in a “nuclear winter”, according to scientists.

Researchers in China have suggested that the heavy smog levels caused by air pollution could have a severe impact on the country’s food chain. With the lack of sunlight breaking through the thick smog, photosynthesis within plants has been slowed down. This impacts growth of all crops, harming agriculture, which could have an economic impact.

Over the last month many cities in the northern region of the country, including Beijing, have been subjected to a heavy amount of smog, caused by low-lying particulate pollution. On Tuesday (February 25th) Beijing was subjected to levels of PM2.5 pollution that measured at 505 micrograms per cubic metre.

This type of pollution is small enough that it can penetrate the lungs, ending up in the bloodstream. It has also been linked to cardiovascular complications and respiratory illnesses. According to the World Health Organization (WHO) a safe level of PM2.5 particulate pollution is 25.
