Heavy metal concentrations were measured in 29 marine wild fish species from the South China Sea. Concentrations (wet weight) were 0.51–115.81ng/g (Cd), 0.54–27.31ng/g (Pb), 0.02–1.26μg/g (Cr), 8.32–57.48ng/g (Ni), 0.12–1.13μg/g (Cu), 2.34–6.88μg/g (Zn), 2.51–22.99μg/g (Fe), and 0.04–0.81μg/g (Mn), respectively. Iron concentrations in all and Mn in some fish species were higher than the acceptable daily upper limit, suggesting human consumption of these wild fish species may pose a health risk. Human health risk assessment, however, indicated no significant adverse health effects with consumption.
