Characteristics and dry deposition fluxes of organochlorine pesticides (OCPs) in atmospheric particulate matters in Western Taiwan Strait during autumn and winter

  • To explore the OCP pollution characteristics of atmospheric particles, possible sources and dry deposition fluxes, 20 OCP compounds were examined in autumn and winter from 2006 to 2008 in the Western Taiwan Strait (Xiamen island, Fujian Province).The results showed that DDTs, HCHs and Methoxychlor were the main component of OCPs in the atmospheric particles.The concentrations of OCP compounds in winter were higher than autumn, which is influenced by the air mass sources during winter in Northern China.Compared with other areas, the average levels of OCP compounds in the atmospheric particles of Xiamen island, which is similar to the levels of background areas.Source apportionment indicated that DDTs, Chlordanes and Endosulfans were mainly historical residue, and the HCHs was mainly effected by industrial HCHs.The total dry deposition flux of OCPs to Xiamen island was 3.49 ng/m2/d and 9.25 ng/m2/d in winter and autumn, respectively, and the average input to the adjacent waters was 20.03 kg and 52.45 kg in autumn and winter, respectively.
