[Method] The pollution distribution of 7 heavy metals total As, Hg, Cd, Pb, Cr, Ni and Cu in potato was analyzed by monitoring heavy metals in potato samples in Inner Mongolia. [Result] Residual heavy metals in potato in producing areas in Inner Mongolia satisfied national limit standards, and comprehensive heavy metal pollution index was smaller than 0.7, belonging to the safe grade. Among the 7 heavy metals, Pb and Cr pollution was relatively heavier, and contributed more to the comprehensive pollution index. The THQ values and the TTHQ value of the 7 heavy metals were all lower than 1, indicating that pollution of heavy metals in potato in Inner Mongolia caused no remarkably risk to human health. Among the 7 heavy metals, Cr content contributed the most to risk to human health, and the risk caused by Cr intake through potato was higher than that caused by other heavy metals. In different sampling regions, there were differences in risk of heavy metals in potato to human health. [Conclusion] This study provides an objective scientific basis for management of quality safety risk of potato.展开更多
