Recently, Zhejiang Provincial Department of Environmental Protection announced the semi-annual report on the air quality of the environment across the province. From January to June this year, there was ups and downs in the air quality in the whole provinc. The average excellence rate of AQI (Air Quality Index) in 11 prefecture cities was 82.2%, which means a  year-on-year increase of 0.5%. Among these cities, the excellence rate of AQI in Wenzhou, Zhoushan and Lishui is over 90%. And a year-on-year rise was seen in the excellence rate of AQI in Jinhua, Wenzhou, Huzhou and Zhoushan while a year-on-year fall in Taizhou, Jiaxing, Lishui, Ningbo, Zhangzhou and Hangzhou.

 

In terms of PM2.5 concentration most concerned by the masses, from January to June, the average was 39 μg/m3 in these 11 prefecture cities, representing a decrease of 4.9% year-on-year; in Jinhua, Quzhou, and Wenzhou, the average decreased notably year-on-year, while in Jiaxing and Shaoxing, the average increased year-on-year.

 

After entering the “dog days”, the weather is getting hotter. In fact, the blue sky and the white clouds in the clear sky in summer can only indicate that the content of PM2.5, PM10 and sulfur dioxide in the air is low, and it does not indicate the improvement of air quality. On the contrary, pollution problems from ozone are often prone to outbreaks in summer and endanger human health. In the first half of this year, there were 14 days of heavy pollution in each prefecture city, an increase of 4 days compared with the same period of last year. And the number of days in which ozone was the primary pollutant was 4 days.

 

According to the forecast of the China National Environmental Monitoring Center of the Ministry of Ecology and Environment, many provinces will have moderate and heavy pollution in the middle and late July, and the primary pollutant is ozone. In this regard, experts from Zhejiang Provincial Department of Environmental Protection reminded that the period of pollution from ozone is mainly in the afternoon, so it is recommended to minimize outdoor activities to effectively avoid pollution.
