Abstract:
Objective:To understand the risk of dietary lead exposure among adults in Xiacheng District of Hangzhou City. Methods:During 2013-2018， commercial foods were randomly collected in Xiacheng District of Hangzhou City for lead content testing. In combination with lead test result and dietary consumption data， the margin of exposure （MOE） method was used to assess the exposure risk of dietary lead. Results:A total of 827 samples from 14 kinds of commercial foods were collected， and the median of lead content was between 0.002 5 mg/kg and 0.100 0 mg/kg. The detection rate was 53.20%， and the over-standard rate was 1.09%. The median of daily dietary lead exposure among adults was 0.174 2 μg/kg BW， and the MOE value was 7.46. Vegetables and fruits were the dominant contributor to dietary intake of lead， accounting for 39.18% and 12.18%， respectively. Conclusion:The exposure of dietary lead among adults in Xiacheng District of Hangzhou City is at an acceptable level. The contribution of vegetables and fruits to dietary lead is higher than other foods， and needs more attention.
