Abstract:
Objectives To investigate the dietary cadmium exposure from rice in Wuhan and to assess the health risk by using Monte Carlo simulation method.
Methods Cadmium in various rice samples randomly collected from markets and super markets was determined by the national standard method (GB/T 5009-2003), the health risk of cadmium exposure from rice was assessed by Oracle Crystal Ball analysis software.
Results The contents of cadmium in all samples were lower than the limited level, and the mean was 0.0619 mg/kg, the standard deviation was 0.0463 mg/kg, the maximum was 0.1800 mg/kg, and the 95th percentile level was 0.1693 mg/kg. The assessment on the health risk of dietary cadmium exposure from rice showed that 8.89% of people might face higher carcinogenic risk brought by cadmium exposure.
Conclusions The levels of cadmium exposure from rice might be acceptable in principle for general population, but it is necessary to strengthen the risk management for 8.89% of people with higher exposure.
