Recently, a research paper entitled "Concentrations, source identification and lung cancer risk associated with springtime PM2.5-bound Polycyclic Aromatic Hydrocarbons (PAHs) in Nanjing, China" composed by Mr. Chong Chen as the first author, a 2013 grade undergraduate student in the School of Environment, has been published in a SCI core journal of Archives of Environmental Contamination and Toxicology (IF=2.467). This work was achieved under the supervision of Assoc. Prof. Zhonghuan Xia.
This paper chose the Xianlin area of Nanjing city as the research area, and the source analysis and exposure risk assessment models of PM2.5-bound PAHs at the seasonal scale were established by using the methods of characteristic compound ratios and Monte Carlo simulation. At the same time, the pollution trends of PAHs at hour scale were also explored. This paper was given a positive evaluation from experts at home and abroad. At present, the researches on the health hazards of PM2.5-bound PAHs in Chinese new urban areas are very limited. The research results of this paper can provide an important scientific basis for the risk management and control of air pollution in the new urban areas of China.
