Changes in the environment

1.1 Atmospheric environment

1.1.1 Status

In 2005, the city's atmospheric environment quality showed an improvement trend. The main components of air pollutants are particulate matter, sulfur dioxide and nitrogen dioxide, of which sulfur dioxide and particulate matter account for a larger proportion. The pollutants mainly come from exhaust gas emitted from coal-fired facilities, vehicle exhaust and secondary dust from urban roads and construction sites. The air environment quality in the downtown area is still Level 3. In 2005, the main pollutant in the ambient air in all counties and cities was total suspended particulate matter. Among them, Luan County and Laoting County reached the national ambient air quality level 2 standard. Luannan County, New District, Tanghai County, Fengrun District, Qian'an City, Yutian County, Qianxi County and Zunhua City have reached the third-level standard. See Figure 1-1.

In 2005, 12 routine monitoring sessions were conducted on 6 major rivers, with 13 monitoring sections and more than 30 monitoring projects. The results show that the water quality of the upstream reservoir section of the river is generally good and can reach Class II water quality. However, after the river section below the reservoir dam site flows through the town, it is polluted by domestic sewage and industrial wastewater, and the water quality is generally poor.

The water quality is good and all meets the standards of centralized drinking water sources.

1.4.2 Atmospheric Environment

In 1986, an automatic monitoring system for ambient air quality was built in Tangshan City. Currently in operation are: supply and marketing cooperative (commercial district) points, radar stations ( Clean area) points and Materials Bureau (traffic area) points, the main monitoring items of ambient air quality are respirable particulate matter, sulfur dioxide and nitrogen dioxide. See Figure 1-5

The overall air quality situation in the downtown area
