Objective To understand the status of the heavy metal pollution in commercial rice,such as Lead,Cadmium and conduct its risk assessment.Methods The heavy metal content in rice was measured by flame atomic absorption spectroscopy method.Results The mean concentrations of lead,cadmium were 0.1101±0.0676mg/kg,0.1142±0.0571 mg/kg respectively.The Risk Index of Lead was 0.2073 while the Risk Index of Cadmium was 0.7667.Conclusion The average content of Lead,Cadmium in rice were lower than that of the national standard,and the health risk index was in the safe range. |
