【摘要】：采用中国总膳食研究方法,运用2012~2014年广东省重金属污染监测工作所采集的大米中的铅、镉检测数据,评估广东省居民膳食中大米的铅、镉暴露情况。开展2012~2014年广东省食品安全风险监测工作,测定大米中的铅、镉含量,计算铅的暴露边界比、镉的每月摄入量,并以此作为评价标准。结果表明,广东省大米中铅、镉总体超标率分别为0.11%和6.22%,除了部分地区大米中镉超标率较高以外(达到16.2%~22.4%),其余大部分地区大米中铅、镉含量均处于较低水平。广东省人群铅的暴露边界比为10.6~42.5;镉的每月摄入量为9.0~27.3μg/kg·BW,占镉暂定每月可耐受摄入量的36%~109%。广东省大米中铅、镉的含量及人群摄入总体处于安全水平。但部分地区的大米镉污染不容乐观且具有地域性差异,人群食用大米的镉暴露潜在一定的风险,尤以粤中北部地区为甚。
[Abstract]:By using the data of lead and cadmium in rice collected from the heavy metal pollution monitoring work in Guangdong Province from 2012 to 2014, the total diet of Guangdong Province was used to evaluate the exposure of rice to lead and cadmium in the diet of Guangdong Province.The food safety risk monitoring work in Guangdong Province from 2012 to 2014 was carried out to determine the lead and cadmium contents in rice, to calculate the exposure boundary ratio of lead and the monthly intake of cadmium, and to use it as the evaluation criterion.The exposure boundary ratio of lead in Guangdong population was 10.6 ~ 42.5, and the monthly intake of cadmium was 9.0 ~ 27.3 渭 g/kg BW, which accounted for 36 ~ 109m of the allowable monthly allowable intake of cadmium.The contents of lead and cadmium in rice and the intake of population in Guangdong Province are generally safe.But the cadmium pollution of rice in some areas is not optimistic and regional difference. The exposure of cadmium to rice is a potential risk, especially in the central and northern part of Guangdong.
