摘要： Seafood is considered as the main source of arsenic in the human diet. In this study, we quantified the total arsenic content in 200 samples of 22 species collected from eight cities in Shandong, China. Subsequently, we evaluated the health risks associated with seafood consumption for three consumption scenarios based on the quantification of inorganic arsenic in three commonly consumed seafood species. The bivalves had the highest total arsenic concentrations in three categories of seafood (fish, shrimp, and bivalves) and the mean total arsenic concentrations ranged from 0.037 μg/g ww in fish to 3.4 μg/g in bivalves. The results suggested that organisms which had a closer relationship with sediments may accumulate more arsenic. Bivalves were the major contributor for the arsenic intakes in the seafood consumers. The margins of exposure (MOEs) estimated in the present work showed that there existed a health risk for the consumers. The carcinogen risks exceeded the acceptable range for life cancer risk. Our results suggested that more attention should be paid to the safety of seafood consumption, especially of benthic economic species and for special consumers.
