Can I call 12345 to complain about the bad air?

Many factors lead to the "red light" of air quality.

Jiang Changtan, deputy chief engineer of the Municipal Ecological Environment Monitoring Center, said that since June 5438+February, due to the adverse meteorological conditions such as static stability, high humidity and low wind, the near-surface atmosphere of our city has been in a relatively stable state for a long time, and its atmospheric diffusion and self-purification ability are extremely poor. Coupled with the prominent phenomenon of open burning and smoked bacon, the air quality in our city has become a "red light".

It is understood that in June this year, 5438+065438+ 10, the number of effective precipitation days in our city was 6 days, 5 days less than 20 19. The rainfall is nearly 20% less, the distribution of precipitation is uneven, and the self-purification ability of the atmosphere is relatively weak. The average air humidity is 8 1%, which is 5% higher than that in 20 19.

"High humidity and foggy weather has promoted the transformation of gaseous pollutants in the atmosphere into particulate matter, resulting in an increase in PM2.5 concentration." Jiang Changtan said.

There is no wet work in many construction sites.
