Hebei orders extra stations in smog fight
Print Edition
More pollution monitoring stations have been set up in north China’s Hebei Province in its latest efforts to fight smog.
Since the beginning of this year, Hebei’s environment protection department has ordered several cities to install devices to collect air pollution data, aimed at setting up a province-wide network.
Handan, one of the first cities to trial the monitoring network, has installed 196 stations.
Sensors have been put up near key industrial plants and major thoroughfares to collect data on six main types of pollutant: sulfur dioxide, nitrogen dioxide, carbon monoxide, ozone and two sizes of particulate matter.
Dust and volatile organic chemicals sensors have been installed near large construction sites and gas stations.
“If certain data goes high, our staff will respond immediately, track the source and send inspectors to intervene,” said Gao Feng, deputy director of Handan’s environment monitoring center.
“In July, several monitoring stations reported high carbon monoxide levels. We immediately studied the data, and found the source of pollution was a steel factory to the north,” he said.
“The steel factory is far from the city, and if it were not for the data, it would be hard to tell the cause,” he added.
Hebei is aiming for a 40 percent cut in PM2.5 density by 2020 compared to 2013 levels. PM2.5 refers to airborne particles smaller than 2.5 microns in diameter that are particularly hazardous to health.
