Abstract
Objective] To evaluate the contents and health risk assessment of lead and cadmium in rice from markets of Yanbian Korean Au-tonomous Prefecture, and to discuss the rice safety of local residents.[ Method] Eighty samples were obtained randomly from markets of Yan-bian eight cities.Lead and cadmium concentrations in rice samples were measured using graphite furnace atomic absorption spectrometer ( GF-AAS).The metal pollution in rice was evaluated by single factor pollution index, and the metal health risk was assessed by exposure model. [Result] The concentrations of Pb and Cd in market rice were 0.13 and 0.04 mg/kg, respectively, in which 10% of the samples contained Pb exceeding the China Health Standards for Food (0.2 mg/kg).There were certain proportions of rice samples were contaminated by Pb form Dunhua, Antu, Helong, Longjing and Tumen Cities.The hazard quotients (HQ) of the health risk were all less than 1, indicating there were no potential health risk of Pb and Cd pollution to residents in Yanbian.[ Conclusion] The Pb pollution exists but Cd pollution does not appear in rice from markets of Yanbian Korean Autonomous Prefecture .The accumulation of Pb and Cd in market rice is not a significant health risk to consumers of Yanbian Korean Autonomous Prefecture.关键词
