N2 - This study aims to investigate levels of POPs in meat, edible oils, nuts, milk and wine collected from Hong Kong. Naphthalene, pp-DDE, beta-, gamma-HCH and PBDE 47 were detected in most of the food items. Goose liver accumulated the highest PAHs (47.9ngg-1 wet wt), DDTs (25.6), HCHs (13.0), PCBs (4.17), PBDEs (468pgg-1 wet wt) among all the selected food. Meat and nut groups had significant (p<0.01 or 0.05) correlations between lipid contents and concentrations of PAHs (meat: r=0.878), HCHs (meat: r=0.753), DDTs (meat: r=0.937; nuts: r=0.968) and PCBs (meat: r=0.832; nut: r=0.946). The concentrations of DDTs, HCHs and PCBs in vegetable oil were lower, but HCHs in fish oil were higher, when compared with other countries. The concentrations of PAHs, DDTs, PCBs and PBDEs in food tested in the present study were all below various safety guidelines.
