摘要： The bioaccumulation of heavy metals in marine fish poses significant threats to human health through dietary exposure. In this work, the contents of 8 heavy metals (arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), manganese (Mn), nickel (Ni) and lead (Pb)) in different tissues of Lagocephalus spadiceus from the Beibu Gulf in China were investigated based on length, weight, age, and size of the fish. The estimated recoveries ranged from 94.6 % to 103.2 %. The ANOVA test results indicated significant variations in the heavy metals concentrations in different tissues. The liver exhibited the highest bioaccumulation capacity for most heavy metals (0.03-11.44 mg/kg). Liver tissues were found to contain the highest concentration of As (11.44 mg/kg) while the gills were found to contain the most Mn (1.86 mg/kg). Notably, neither sexual dimorphism nor age-dependent accumulation patterns were observed for most metals. Health risk assessment revealed acceptable hazard indices for muscle consumption but identified potential carcinogenic risks from liver intake.
