Why is the smog weather in Shijiazhuang the most serious?

There are many reasons: First, there is little cold air activity in the provincial capital in June 5438+ 10, and the atmosphere above is stable. In addition, the humidity in the air near the ground is high and the temperature is low at night, which leads to haze weather, no diffusion and serious pollution is inevitable; Secondly, the unique geographical location makes it difficult for air pollutants in Shijiazhuang to spread, which is obviously transported by foreign pollutants of various scales. According to the analysis of meteorologists, there are two obvious pollutant gathering areas from Shijiazhuang to Cixian and from Shijiazhuang to Tianjin, and Shijiazhuang is the gathering area of two convergence zones, which leads to the aggravation of air pollution. "These meteorological and geographical conditions are objective factors that easily lead to the accumulation of air pollutants, but it is undeniable that man-made pollution is the crux of the problem." Zhang Ju said frankly that it is the increase in air pollutant emissions caused by people's production and living activities that leads to more frequent smog weather and more serious air pollution.

The main human factors leading to smog are coal burning, automobile exhaust, dust and industrial pollution. "At present, Shijiazhuang is analyzing the source of PM2.5. After the results come out, we can analyze the proportion from a quantitative perspective. However, there is no doubt that the increasing amount of coal and the number of motor vehicles are important factors causing the increase of PM2.5 emissions. In addition, there are 6 12 construction sites in Shijiazhuang city, and some dust prevention measures are not in place; The secondary dust emission of traffic roads such as national highways and provincial highways, especially the main coal transportation channels in western counties (districts), is still heavy, which is also an important reason for the increase of PM2.5 emissions.

The energy structure and industrial structure are unreasonable.

In the continuous smog, many citizens and netizens are constantly asking questions: isn't the provincial capital already engaged in the blue sky project, has not pulled out many black chimneys, and many heavily polluting enterprises have moved out of the city? Why are smog and heavily polluted weather threatening when the weather conditions are bad?

The prevention and control of motor vehicle pollution started late, and the oil standard is still low.

Automobile exhaust pollution is increasing year by year. Sulfide and particulate matter are the main culprits of haze weather. The requirement of sulfur content in gasoline and diesel oil in the fourth national standard is three times stricter than that in the third national standard. If the fourth national standard is implemented, the sulfide concentration emitted by automobiles will be greatly reduced accordingly. At present, Shijiazhuang uses gasoline of national standard 3. According to the requirements of the province, Shijiazhuang will implement the national four standard gasoline in June this year, vigorously promote the upgrading of vehicle oil products, and accelerate the pace of low vulcanization of vehicle fuel. We will gradually supply gasoline and diesel for automobiles that meet the national four standards, and actively coordinate oil production and sales enterprises to meet the supply. Quality supervision, commerce, industry and commerce, environmental protection and other departments to carry out vehicle oil quality supervision and inspection, improve the quality of vehicle oil.
