Air, water, dry particulate, and wet deposition samples were collected to estimate the air-water mass transfer coefficient at Honghu Lake, China, 2005-06. Collected samples were analyzed by using gas chromatography with electron capture detection (Agilent 6890 GC-ECD). Concentration vs. flux of α-HCH (1,348 ng m⁻²・m⁻¹) was found to be higher volatilization in atmosphere in the month of March; however δ-HCH (286 ng m⁻²・m⁻¹) was deposited in water body. Further, p,p′-DDE (380 ng m⁻²・m⁻¹) metabolite was higher in Honghu lake atmosphere. The ratios of p,p′-DDE/p,p′-DDT and o,p′-DDT/p,p′-DDT indicated recent use of DDT and dicofol in Honghu Lake. The α-endosulfan (640 ng m⁻²・m⁻¹) was also found to be more deposited in the water body compared to β-endosulfan.
