| 英文摘要 | Context. Wild fish is a good source of minerals and other high-quality nutrition; however, many wild fish species potentially accumulate hazardous metals, making them a threat to human health.Aims. The aim was to study characteristics and the source of metals in wild fish in the South China Sea by using, for the first time, the correlation of trace metals and stable isotopes.Methods. Analytical instruments and statistical methods were respectively used to determine elements and the relative correlations.Key results. Lead (Pb) and manganese (Mn) tended to accumulate in bluespot mullet and Macao tonguesole. Variation among fish species and spatial differences might be two important factors influencing both the metal concentrations and the selenium (Se):mercury (Hg) molar ratios in biota. Hg, Mn, Pb and tin (Sn) tended to be biomagnified with an increasing trophic level, whereas chromium (Cr) and copper (Cu) showed a trend of biodilution.Conclusions. The Se:Hg molar ratios exhibited noticeable species and spatial variation for the wild fish, whereas the main sources of Sn and Pb contamination might be antifouling reagents and surface applications.Implications. The speciation of the elements is worth investigating next, so as to obtain valuable insight into the state of the wild environment and the impacts to human wellbeing. |
