In the first half of the month, the concentration of the intensive and rough particles in Beijing (townships) in Beijing was released!

The Beijing Ecological and Environment Bureau reported on the 19th that from July 1st to 15th, 2022, the city's tenth streets (townships) were ranked in the city. District Chief Xindian Street, Gongchen Street, Fangshan District, Wangzuo Town, Fengtai District, Gaomian Street, Daxing District, Yuxing Town, Daxing District, Heping Street Street, Chaoyang District, Daxing District Lin School Road Street, and Asian Games Village, Chaoyang District. It is mainly distributed in the southwest, involving four districts: Fengtai, Daxing, Fangshan and Chaoyang.

In the first half of the month, 30 streets (townships) with the highest concentration of atmospheric particles in the city, the top three streets and latter three streets (townships) in each district were as follows.

July 1st to 15th, the city's street (township) TSP concentration ranking

Unit: micrograms/cubic meter

Thick rough particles

Generally, the total suspended particulate matter (TSP) is characterized, that is, particles with a particle size of less than 100 microns. The concentration level of TSP is affected by various factors such as regions, seasons, and local environments. The wind and sand in the northern cities are relatively large, and the particles with large particle size in TSP accounted for more. The time of different particles of particulate matter stays in the air and the transmission distance is very different. The larger the particle size, the shorter the stay in the air, and the closer the transmission distance. Therefore Pollution of the ground environment.
