Under the support of the National Natural Science Foundation of China (Grant No.
21876028, 91743202, 21625701, 92043302), researcher Li Qing of Fudan University, Prof.
Wang Shuxiao of Tsinghua University, and Prof.
Li Xiangdong of Hong Kong Polytechnic University cooperated to study the pollution based on the exposure of aerosol population to health risks.
New progress has been made in the prevention and control mechanism.
The relevant research results are published on January 6, 2022 under the title of "Toxic potency-adjusted control of air pollution for solid fuel combustion".

Fuel combustion is the main energy source for modern society and economic development, and a large amount of combustion by-products will be released into the atmosphere along with flue gas, resulting in negative environmental effects such as air pollution and global climate change
.

In response to this problem, the collaborative team revealed the factors affecting the combustion efficiency of key toxic components (polycyclic aromatic hydrocarbons and heavy metals) in aerosols during coal and biomass combustion through multidisciplinary integration, and quantified the key toxic chemical groups.
Contributions to cytotoxic effects (carcinogenic and genotoxic) and underlying mechanisms
.

Through rigorous actual emission source measurement, chemical/biological analysis and model analysis, this work has put forward new ideas for the current China and WHO pollution control strategies based on PM2.
