Why can't Guangzhou and Shenzhen eat barbecue from September?

On August 4, 20 17, the reporter learned from the municipal environmental protection bureau that the provincial environmental protection department issued the "Implementation Plan for the Special Action for the Prevention and Control of Ozone Pollution in Autumn in the Pearl River Delta Region in 20 17 (draft for comments)", in which a number of specific measures were put forward for the prevention and control of ozone pollution.

From September, the Pearl River Delta region will launch a three-month special campaign to prevent and control ozone pollution, and four cities including Guangzhou, Shenzhen, Foshan and Dongguan will be designated as demonstration zones for ozone pollution prevention and control. These four cities will carry out special rectification actions, such as peak-shifting production of VOCs emission enterprises, banning all open-air incineration and open-air barbecue in urban built-up areas, and completely suspending asphalt pavement laying of municipal roads in weather with ozone exceeding the standard.

According to reports, in the first half of this year, the average number of days for urban air quality in the province was 965,438 0.6%. Among the air pollution sources in the province, ozone has replaced PM2.5 and become the primary air pollutant in the province. Monitoring data show that in the first half of this year, the proportion of ozone as the daily primary pollutant was 41.8%; Followed by PM2.5, accounting for 32. 1%.

In the second half of 20 17, Guangzhou and other four cities will strengthen the coordinated control of ozone and PM2.5, implement the special action of air pollution prevention and control in summer and autumn of 20 17, control and reduce ozone precursor pollutants such as volatile organic compounds and nitrogen oxides through a series of key areas and key pollution sources, and take targeted emission reduction control measures to effectively achieve the effect of "peak cutting", curb the deterioration of ozone pollution and promote the city.
