Objective To analyze the arsenic level in main foods, and assess the risk of dietary exposure of inhabitants in Jilin Province. Methods Arsenic concentration data were obtained from the national food contamination program during 2012-2017. Food samples (n=4 532) were collected from 11 food categories in Jilin Province. Consumption data were derived from Jilin provincial nutrition and health survey in 2012. The provisional tolerable weekly intake (PTWI) and margin of exposure (MOE) were used to estimate dietary arsenic exposure of inhabitants in Jilin Province. Results The average concentration of arsenic in 11 categories of food was 0.030 mg/kg. Cereals, vegetables and aquatic products were the main source of dietary arsenic exposure. The contribution rate of the three was 76.59%, of which cereal contributed 54.44%.Dietary arsenic exposure of different age-gender population groups was in the range of 0.73-1.31 μg/kg BW. The MOE of mean dietary arsenic exposure was above 1. Conclusion The status of arsenic exposure of the inhabitants in Jilin Province was safe.
