To evaluate content characteristic and health risk of heavy metal in rice and corn from Jiangjin District, Chongqing City, sixty-three rice samples and sixty-four corn samples were collected from 2019 and analyzed by ICP-MS and AFS. The arsenic(As), barium(Ba), cadmium(Cd), copper(Cu), iron(Fe), manganese(Mn), molybdenum(Mo), nickel(Ni) and zinc(Zn) were took into account. The health risk of heavy metal was evaluated using environmental health risk assessment model. The results showed that the maximum mass fraction of As in rice and corn were 176.0, 162.8 μg/kg, respectively, which were lower than that of national food hygiene standards(<200 μg/kg). The Cd content in three rice samples and six corn samples were exceeded the national food hygiene standard(Cd mass fraction of rice<200 μg/kg, Cd mass fraction of corn<100 μg/kg). The mean value of mass fractions of As and Mo in rice were significant higher than those of corn, while the mean value of mass fractions of Cd in rice was slightly above that of corn. The single factor pollution indexes of As, Cu, Mn and Zn in rice were less than 1.0 with clean level. The pollution level of Cd in three rice samples were slight. The synthetic index of heavy metal in rice and corn were 1.09 and 1.57, reaching the slight pollution, and heavy metal contamination of corn was higher than that of rice. The carcinogenic risk of As and Cd in rice accounted for 82.7% and 16.8% of total health risk, indicating that the heavy metal of maximum potential risk was As, the second was Cd. The results together indicated that the content and health risk of As and Cd in crops from area of Chongqing should be given strengthened surveillance.
