Abstract:

In this study, we analyzed the concentrations of heavy metals of Carassius auratus and water from Datun Lake, Yunnan province. By using the microwave digestion method, though the TAS-990 atomic absorption spectrophotometer,zinc, copper, two kinds of heavy metal contents of tissues of Carassius auratus were detected. The results showed that the heavy metals concentrations of Carassius auratus were: zinc（10.9±3.4）mg/kg, copper（3.51 ± 0.25）mg/kg, respectively. Heavy metal concentrations of water from Datun Lake were: zinc（13.4 ± 2.28）mg/kg, copper（9.8 ± 0.72）mg/kg respectively.

Key words: heavy metal, atomic absorption spectrophotometer, Carassius auratus
