Tracking the quality of air we breathe
Minhang District’s air quality has been improving for the past five years, with “fine” conditions rising to 82.7 percent of last year from 70.4 percent in 2015.
At the air quality monitoring station in Xinzhuang, engineer Ma Hui watches the statistics.
The site has machinery that extends all the way to the roof. It extracts air samples and automatically analyzes content of sulfur dioxide, carbon dioxide and other hazardous particles, particularly those in the PM10 and PM2.5 indexes.
Visitors can also climb onto the roof to see exactly how the extraction is done.
The station is responsible for more than 160 kinds of tests in eight categories, including water, air, soil and waste gas, said Lu Yongjun, the station’s Party secretary.
Last year the station was opened for scientific tours. “We hope more people interested in environmental protection will come visit,” said a worker at the station.
