【摘要】：为量化江苏地区人群克氏原螯虾镉的膳食暴露量,以江苏地区克氏原螯虾为研究对象并运用石墨炉原子吸收光谱法进行检测,同时结合获得镉的检测数据和江苏地区人群的膳食消费量,运用点评估和概率评估两种方法评价江苏地区克氏原螯虾中镉的膳食暴露及风险。结果显示:江苏地区705个克氏原螯虾样品中镉含量的平均值为0.068 mg/kg,有2个样品的镉含量超标,超标率为0.28%。点评估结果显示,江苏地区人群克氏原螯虾镉的暴露量的平均值、75分位数和90分位数分别占暂定每月耐受摄入量(provisional tolerable monthly intake,PTMI)的0.07%、0.05%和0.32%。概率评估结果显示,江苏地区人群食用克氏原螯虾的镉暴露量的平均值、75分位数和90分位数分别占PTMI的0.08%、0.10%和0.21%,江苏地区91.6%人群镉的暴露量处于安全水平。江苏地区人群克氏原螯虾镉的膳食暴露量总体处于安全水平范围内,长期食用克氏原螯虾不会增加总膳食镉的摄入量。
[Abstract]:In order to quantify the amount of cadmium exposed to cadmium in the population of Jiangsu Province, the shrimp was studied and detected by graphite furnace atomic absorption spectrometry (GFAAS). At the same time, combined with the data of cadmium detection and the dietary consumption of the population in Jiangsu, the point assessment and probability evaluation were used to evaluate the dietary exposure and risk of cadmium in the crayfish in Jiangsu. The results showed that the average cadmium content in 705 samples of crayfish was 0.068 mg/kg,. The cadmium content of 2 samples exceeded the standard and the rate of exceeding the standard was 0.28%. The results of point assessment showed that the average of cadmium exposure, 75 quartile and 90 quartile of cadmium exposure in Jiangsu population accounted for 0.07% and 0.32% of (provisional tolerable monthly intake,PTMI respectively. The results of probabilistic evaluation showed that the average value of cadmium exposure, 75 quartile and 90 quartile of PTMI in Jiangsu population accounted for 0.08% and 0.21% of PTMI, respectively. Cadmium exposure was at a safe level in 91.6% of the population in Jiangsu province. The dietary exposure to cadmium in the population of Jiangsu Province was generally within the safe level, and long-term consumption of the shrimp did not increase the intake of total dietary cadmium.
