Causes of air quality deterioration in Guangzhou

According to the air monitoring data published on the website of Guangzhou Environmental Protection Bureau, yesterday's air quality index (API) was 1 14. It is understood that yesterday's air quality ranked second in the first three months of this year.

The reporter saw in the Air Quality Daily on the website of Guangzhou Environmental Protection Bureau that yesterday, among the air monitoring points in the whole city 10, except the West Village was "good", the other nine were lightly polluted, and the primary pollutant was inhalable particulate matter. The pollution index of inhalable particulate matter in Jixiang Road in Yuexiu District is 128, which is the most serious place in the urban area, and so is Land Rover Lake at the foot of Baiyun Mountain. The pollution index of inhalable particulate matter in Luogang Kowloon reached 165, the highest in the city. The air quality in the first 2 1 day was "good".

According to the air monitoring data of Guangzhou Environmental Protection Bureau, the air quality was poor for the first time on June 265438+1October 2 1 this year, and the API index was as high as 124.

The reporter asked the relevant person in the environmental protection department whether the deterioration of air quality in Guangzhou was related to the drought and sandstorm in southwest China, and did not get a positive answer.

Not suitable for human habitation?

The sandstorm cheered the sudden change of air.

The reporter learned from the Provincial Meteorological Observatory yesterday that the air quality in Guangzhou suddenly deteriorated yesterday, which was indirectly related to the sandstorm weather in the north.

Lu shan, the chief forecaster, told reporters that the air quality deteriorated this time because cold air was blowing all the way along Mongolia, Central China, East China and South China, and the cold air also carried a lot of particles. When passing through North China, it caused sandstorm weather. The east wind blew yesterday afternoon, so the particulate matter was brought to the coast of South China. In fact, Guangzhou is not the most serious area, and particulate pollution is more serious in coastal areas such as Shanwei, Shenzhen and Hong Kong.

However, the air quality in Guangzhou has deteriorated, and there are many reasons for the pollutants in the Pearl River Delta region itself. It is expected that there will still be fog in Guangzhou today, and the situation will not be alleviated until the cold air strikes tomorrow, and the wind and rainfall will increase. "
