摘要: Abstract The major aim of this study was to investigate heavy metal content edible fish in the PRD. Eleven species (consisting 711 individuals) [catfish (Clarias fuscus), tilapia (Oreochromis mossambicus), grass carp (Ctenopharyngodon idellus), bighead (Aristichthys nobilis), mandarin (Siniperca kneri), snakehead (Channa asiatiea), black bass (Micropterus salmoides), mangrove snapper (Lutjanus griseus), star (Lutjanu stellatus), snubnose pompano (Trachinotus blochii) and orange-spotted grouper (Epinephelus coioides)] were collected for analyses metals. Overall concentrations (mg/kg, ww) muscles were: As (0.03–1.53), Pb (0.03–8.62), Cd (0.02–0.06), Ni (0.44–9.75), Zn (15.7–29.5), Cr (0.22–0.65), Cu (0.79–2.26), Mn (0.82–6.91). Significant level found at all locations. It is recommended that different must be determined on a regular basis future so as reduce human health risks from acute chronic food intoxication.
