| Abstract: |
| To comprehensively understand the residual characteristics and food hazards of organochlorine（OCP）and pyrethroid（PYR） pesticides in marine products from the eastern China coastal seas, typical marine products from the target area were collected and analyzed using gas chromatography–tandem mass spectrometry. The ∑OCPs ranged from 2.2 ng·g-1 to 1 864.7 ng·g-1（ calculated by dry matter）, with a mean of 72.5 ng·g-1, and ∑PYRs ranged from 5.2 ng·g-1 to 761.7 ng·g-1, with a mean of 57.9 ng·g-1. ∑OCPs were more likely to accumulate in fish with higher fat content than in mollusks and crustaceans; however, the bodily residues of ∑PYRs showed no significant difference among the three types of organisms. In addition, the spatial differences of the two pesticides in marine organisms were not significant（except Yantai coastal water）. OCPs mainly left over by history, while PYRs may be closely related to human activities in the land area near the offshore. The total risk index of two types of pesticides in seafood was much lower than 1, with no significant health risk. |
