Environment Officials to Implement Mandatory Measures to Help Curb Pollution
Environmental officials said that the air quality in Shenzhen deteriorated during the first quarter of the year compared with the same period last year, prompted officials to implement several mandatory measures that they hope will curb pollution.
88 of the 90 days in the first quarter the air quality have reached a good or fairly good level which is only two days fewer that the first quarter of last year. This showed that the levels of several pollutants have increased. The average concentrations of sulfur dioxide increased by 0.004 milligrams per cubic meter and the levels of carbon monoxide, PM2.5 PM10 and nitrogen dioxide have increased a few milligrams per cubic meter each respectively.
Officials said that the worsening of the air quality was due to the citywide Metro construction projects and low rainfall. The average rainfall and rainy days from January and February felled 50 percent compared to last year, even with the amount of rainfall in March was high it was still a few days short that of March last year. Average wind speed is lower as well which slows down the dispersal of air pollutants.
Environmental officials are now working with the city meteorological observatory in developing an air quality warning system. When air quality reaches low level of harmful pollution the environmental commission will then issue a warning on their microblog advising people to shorten or avoid lengthy outdoor activities.
