North China's Hebei province has set up more stations to precisely monitor pollutants in the air as its new efforts to fight against smog.
Since the beginning of this year, Hebei provincial environment protection department has ordered several cities to install devices to collect air pollution data, aimed at setting up a province-wide network.
Sensors have been put up near key industrial plants, main thoroughfares and airways in the city to collect data on six main types of pollutants: sulphur 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.
Hebei is aiming for a 40 percent cut in PM 2.5 (airborne particles smaller than 2.5 microns in diameter) density by 2020 compared to 2013 levels, through slashing excessive industrial capacity.
