Temperature Has Significant Influence on Air Pollution in Heating Season of Northeast China City


There was a strong positive correlation between three types of particles and air pollution.

Coal-fired central heating is widely used in the winter in Northeast China, and the consumption of fossil fuels for winter heating could produce a large number of fine particulates, sulfides and nitrogen oxides, which aggravates the air pollution situation in Northeast China in winter.

Researchers LI Chunlin, LIU Miao, HU Yuanman and their collaborators from the Institute of Applied Ecology of the Chinese Academy of Sciences analyzed the distribution characteristics of gaseous pollutants and particulate matter, and explored the main factors affecting the variation in pollutants.

The researchers measured the concentration of air pollutants on two main roads in Shenyang by a vehicle-borne air pollutant monitor. And they found that the average concentration of SO2 was similar under different air pollution conditions. SO2 was negatively correlated with other pollutants, while NO2 and particulate matters were positively correlated.
