To evaluate dietary exposure of cadmium and their potential health risks of adults in Jiangxi Province.
The concentration data of cadmium of 11 kinds of foods were obtained from food safety monitoring in Jiangxi Province in 2012-2017. The food consumption data was obtained from food consumption survey in Jiangxi Province in 2016. Based on the deterministic assessment model, the dietary exposure of cadmium of adults in Jiangxi Province was calculated.
The average dietary exposure of cadmium was 18. 426 μg/kg per month, accounting for 73. 7% of the provisional tolerable monthly intake(PTMI). The large portion exposure(P95) of cadmium was 29. 724 μg/kg per month, accounting for 118. 9% of PTMI. The average and the large portion(P95) dietary exposure range of cadmium in different age groups were 16. 224-19. 774 and 24. 059-33. 387 μg/kg per month, respectively. It was indicated that the main dietary sources of cadmium were rice and vegetables, which were contributed more than 92% of total dietary exposure of cadmium.
The potential health risks caused by dietary exposure to cadmium of adults in Jiangxi Province was at an acceptable level. But there were some potential health risks in high exposure population.
评估江西省成年人镉的膳食暴露水平及其潜在健康风险。
获取2012 - 2017年江西省食品安全监测中11种食品的镉浓度数据，以及2016年江西省食物消费量调查数据。基于确定性评估模型，计算江西省成年人镉的膳食暴露量。
镉的平均膳食暴露量为每月18.426μg/kg，占暂定每月耐受摄入量（PTMI）的73.7%。镉的高暴露量（P95）为每月29.724μg/kg，占PTMI的118.9%。不同年龄组镉的平均和高暴露量（P95）膳食暴露范围分别为每月16.224 - 19.774μg/kg和24.059 - 33.387μg/kg。结果表明，镉的主要膳食来源是大米和蔬菜，其贡献率超过镉总膳食暴露量的92%。
江西省成年人膳食镉暴露所致的潜在健康风险处于可接受水平。但高暴露人群存在一定潜在健康风险。
