Air pollution reaches hazardous levels
Print Edition
AIR pollution in the northeastern city of Shenyang, capital of northeast China’s Liaoning Province, reached extremely hazardous levels yesterday, as people living in northern China began burning coal to heat their homes.
Real-time data released by the Shenyang Environmental Protection Agency showed the density of the poisonous tiny airborne matter known as PM2.5 was more than 1,000 micrograms per cubic meter.
Nearby cities also reported very high levels of the harmful particulates.
The World Health Organization considers the safe level of PM2.5 to be 25 micrograms per cubic meter on a 24-hour average basis.
Local authorities said they have warned residents to stay indoors and demanded power plants to cut output.
People in northern China burn coal for heating, a practice believed to have fouled the air. Industrial emissions and vehicle exhaust fumes are also major causes of air pollution.
