During the summers of years 2005,2006 and 2007,68 species of commercial aquatic products were collected from Mindong ecological monitoring area,Fujian east coast,P.R of China,and the residues of hexachlorobenzene(BHCs)and dichloro-diphenyl-trichloroethane(DDTs)were quantified by gas chromatography.The residues levels,distribution patterns and compositions of BHCs and DDTs,as well as the pollution status and the risk to human health were also evaluated and discussed.The results showed that,the residues of BHCs in shellfish,shrimps,crabs and fishes ranged from undetected to 1.53 μg/kg,undetected to 0.830 μg/kg,undetected to 1.21 μg/kg,undetected to 4.02 μg/kg,in wet weight respectively; and the residues of DDTs ranged from 0.184 to 66.9 μg/kg,undetected to 2.87 μg/kg,8.04 to 126 μg/kg,0.891 to 310 μg/kg,in wet weight respectively.BHCs pollution index was below 0.5,which indicated that commercial aquatic products along Mindong ecological monitoring area had not been polluted by BHCs.71.2% of tested samples with the DDTs pollution index range from 0.581 to 31.0,which indicated they had been more or less polluted by DDTs.BHCs levels in organisms from Mindong ecological monitoring area were lower compared with those reported in other sea waters at home and abroad.DDTs residues were in the middle levels compared with those reported in domestic adjacent waters and were relatively higher compared with those reported in AsiaPacific region waters.The average ratios of p,p′-DDT/DDTs in shellfishes and fishes were 43.8% and 49.1% respectively.High percentage of p,p′-DDT content may suggest that some contaminants such as DDTs had input into the Mindong ecological monitoring area in recent years.The residues levels of BHCs and DDTs were below the Maximum Residual Limits published by the European Union,USA and Japan; and met the sea food safety index set by Chinese government.The risk of organochlorine pesticides to human health was assessed according to RfD (reference dose),and cancer slope factor suggested by EPA(US EPA,2000).The analyzing of ERI(exposure risk index)and CRI(carcinogenic risk index)indicated that the exposure risk and carcinogenic potential arising from the exposure to BHCs and DDTs due to the consumption of aquatic product in Mindong ecological monitoring zone were within acceptable ranges.
