DDTs, chlordanes and hexachlorobenzene in the atmosphere of Chinese cities
Passive air samplers (PAS) were therefore utilized to obtain seasonal data from 37 Chinese cities in 2005. Concentrations and spatial and seasonal distribution of dichlorodiphenyltrichloroethanes (DDTs), chlordanes (CHLs) and hexachlorobenzene (HCB) are presented in this paper, and their potential sources are discussed based on the dataset. The authors suggested that approximately 95％ of DDTs in the Chinese cities was still technical DDT, for which DDT application for public health control and DDT activated antifouling paint for fishing ships may be the major sources. A low TC/CC ratio was observed across China in the winter to spring, maybe related to the secondary emission from past use of chlordanes for house protection. The data showed that China is an important global source for HCB, and combustion may be an important HCB source.
