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.

July 1st to 15th, the city's street (township) TSP concentration ranking
(Later)
July 1-15 TSP concentration
The top three, the first three streets (townships) in the first three,
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.
