Abstract: To assess level of human mercury exposure in Zhoushan area, the total mercury (THg) concentrations in 150 samples of seafood and 136 human hair samples were analyzed. THg concentrations in the seafood ranged 3.73-789 μg·kg^-1 in wet weight with an average of 43.9 μg·kg^-1, which was lower than the national limit of China. There were significant differences of THg concentrations among different species in the seafood. Fish THg concentration was correlated with the body length and weight. The THg concentrations in human hair samples ranged 0.13-8.18 mg·kg^-1 with an average of 1.77 mg·kg^-1. There was 84.6% of population with hair THg concentrations higher than 1 mg·kg^-1 set by USEPA, and 7.4% higher than 2.3 mg·kg^-1 set by the Joint FAO/WHO Expert Committee on Food Additives. Hair THg concentrations showed an increasing trend with the age of studied population and males showed significantly higher hair THg concentrations than females. The results suggested that THg concentrations in the seafood in Zhoushan area were relatively low, but local residents still might have health risk of mercury exposure because of large consumption of seafood.
