Bioenrichment preference and human risk assessment of arsenic and metals in wild marine organisms from Dapeng (Mirs) Bay, South China Sea

Bioenrichment preference of arsenic and metals in wild marine organisms has been scarcely considered. Twenty species including fishes, cephalopods, crustaceans, and bivalve mollusks were collected from Dapeng (Mis) Bay and analyzed for arsenic and metals. Through this study, we had obtained the following four main conclusions: (1) average concentrations of arsenic and metals (& mu;g/kg, wet weight) in the aquatic organism samples were 48.7 for Cr, 1762.0 for Mn, 20,632.8 for Fe, 33.0 for Co, 119.5 for Ni, 3184.7 for Cu, 12,040.5 for Zn, 389.0 for As, 189.1 for Se, 144.4 for Cd, 15.0 for Hg, and 55.3 for Pb; (2) factor analysis (FA) revealed that the studied twenty species exhibited three types of arsenic and metal bioenrichment preference;(3) non-carcinogenic health risk assessment indicated insignificant health effects from marine organism consumption; (4) carcinogenic health risk assessment revealed an unacceptable risk from consumption of nine species, seven of which were crustaceans.

Automated summary

Bioenrichment preference of arsenic and metals in wild marine organisms has been largely overlooked. In this study, twenty different species from Dapeng (Mis) Bay were analyzed for arsenic and metal content. The findings revealed four main conclusions: (1) The average concentrations of arsenic and metals in the aquatic organisms were measured, with varying values for each element; (2) Factor analysis demonstrated three distinct types of bioenrichment preference; (3) Non-carcinogenic health risk assessment showed insignificant effects on human health from consuming marine organisms; (4) Carcinogenic health risk assessment indicated an unacceptable risk from consuming nine species, primarily crustaceans.
