The rise in air pollution levels in Tianjin is affected by these factors

The careful citizens of HC Xinfeng.com can find that the air quality of Jincheng has been good in the last two or three months, but from the end of June to the beginning of July, as the temperature gradually increases, the pollution situation is aggravated, often in the morning, the curtains are opened. There is a layer of smog in the sky. According to the recent monitoring data of the Ministry of Environmental Protection, the air pollution level in Beijing, Tianjin and Hebei and surrounding areas has increased due to adverse meteorological conditions. The concentration of PM2.5 in Tianjin and other cities increased from late late June to early July.

Jincheng's recent increase in PM2.5 concentration

It was learned from the Municipal Environmental Monitoring Center that as of 13:30 today (July 6), the AQI Index 204 of the Binshui West Road in Nankai District, which has the most air pollution in the past 24 hours, was heavily polluted, and the PM2.5 was 154 in the last hour. O3 is 124, the primary pollutant PM2.5. From late late June to the present, Tianjin's primary pollutants also alternated between PM2.5 and ozone, and the highest pollution has reached four levels of pollution, and in the early stage is basically between the first grade and the second grade. Hey. The public also personally felt the change in air quality.

Air slip is affected by these factors

Experts from the Ministry of Environmental Protection said that the recent deterioration of air quality in the Beijing-Tianjin-Hebei region was firstly affected by meteorological conditions into the “sauna days”, which was not conducive to the spread of pollutants and the accumulation of regional pollutants. The eastern and southeastern parts of the Beijing-Tianjin-Hebei region, such as Tangshan, Beijing, and Tianjin, are more affected and the atmosphere is more stable. This is also a factor in the recent increase in air pollution levels. Coal-fired pollution caused by motor vehicle pollution and transmission properties is a major factor in the recent deterioration of air quality, especially the high PM2.5 concentration. In addition, the transmission of the eastern and southeastern passages of the Beijing-Tianjin-Hebei region is also an important factor for the continued high concentration of pollution.

High air pollution concentration this month

Judging from the recent forecast of climate trends, the surface temperature in the Beijing-Tianjin-Hebei region was high in the first half of July, and the overall characteristics of weak air pressure, high temperature and low rainfall were maintained in the second half of the month. It is expected that the current unfavorable air pollution diffusion conditions will continue and the air pollution concentration will be high. The Ministry of Environmental Protection will continue to pay close attention to the air quality situation and timely announce the air quality monitoring to the public. At the same time, it is recommended that the public reduce the amount of outdoor sports and call for public transportation to reduce the number of cars on the road.
