抄録

Occurrence of organochlorine pesticides (OCPs) including hexachlorocyclohexane (HCH), hexachlorobenzene (HCB), drins, heptachlors, chlordanes, dichlorodiphenyltrichloroethane (DDT) and mirex in 19 food items collected from Shandong Peninsula were investigated and estimated the potential health risk of dietary intake. HCHs (including α, β, γ and δ-HCH) were ubiquitous components in the study area with the highest total concentration found in peanut oil (2.4 ng/g) and the composition of HCHs indicated the mainly historical usage of technical HCHs and recent input of lindane. Although high sum concentrations of DDTs (including o,p’-DDE, p,p’-DDE, o,p’-DDD, p,p’-DDD, o,p’-DDT and p,p’-DDT) were found in croaker (72 ng/g ww), the value was still far below the Chinese safety guidelines (500 ng/g). The composiion of DDTs metabolites revealed the recent input which may be attributed to the antifouling paints leakage from transportation sources. However, the detection of Σ209 polychlorinated biphenyls (PCBs) were only conducted in 5 marine food items with rather lower concentration ranged from 0.33 ng/g to 3.1 ng/g ww. It was interesting that PCB #11 and Hexa-CBs were frequently detected with high proportion to total PCBs compared to other homologues. According to the Integrated Risk Information System (IRIS), the average daily exposure for each contaminant in foodstuffs was lower than the corresponding benchmark concentration based on cancer and non-carcinogenic effects. To date, the work provided the first data about the existence of non-Aroclor PCB #11 in foodstuffs from China and should arouse much attention from a toxicity point.
