To evaluate the potential risk of lead and cadmium through vegetables and edible fungus in Nanjing City from 2014 to 2018.
Based on the survey of dietary consumption of residents in Nanjing City, combining with the concentration data of lead and cadmium in vegetables and edible fungus, using @Risk software to simulate and analyze the cumulative dietary exposure in a probabilistic way, and compared with the health guidance value or benchmark dose(BMD) to assess the potential health risks of lead and cadmium for Nanjing residents.
The average exposure of lead and cadmium was 0.237 and 0.090 μg/kg, the exposure of cadmium in the general population were lower than the corresponding health guidance value, meanwhile the margin of exposure(MOE) for lead was higher than 1 in 18-49 years old group and over 50 years old group respectively, except for the high-end exposure(P95) in 6-17 years group the MOE for lead was 0.9. The pollution level and the consumption of leafy vegetables, edible fungus and artemisia selengensis were the main factors affecting the exposure of lead and cadmium through vegetables and edible fungus.
The exposure to lead and cadmium through vegetables is at a relatively safe level, but more attention should be paid to the risk of lead and cadmium exposure in 6-17 years old and over 50 years old group of high-end exposure population.
评估2014年至2018年南京市蔬菜和食用菌中铅和镉的潜在风险。
基于南京市居民膳食消费调查，结合蔬菜和食用菌中铅和镉的浓度数据，使用@Risk软件以概率方式模拟分析累积膳食暴露情况，并与健康指导值或基准剂量（BMD）进行比较，以评估南京市居民铅和镉的潜在健康风险。
铅和镉的平均暴露量分别为0.237和0.090μg/kg，一般人群中镉的暴露量低于相应的健康指导值，同时18-49岁组和50岁以上组铅的暴露边际（MOE）分别高于1，6-17岁组除高端暴露（P95）外铅的MOE为0.9。蔬菜和食用菌的污染水平以及叶菜类、食用菌和藜蒿的消费量是影响铅和镉通过蔬菜和食用菌暴露的主要因素。
通过蔬菜摄入铅和镉处于相对安全水平，但应更多关注6-17岁和50岁以上高端暴露人群的铅和镉暴露风险。
