【摘要】：目的对河南省居民膳食中铅、镉暴露情况进行评估,掌握居民膳食中铅、镉的摄入情况和危害程度。方法 2013—2014年对河南省10类食品进行铅、镉含量的监测,利用2002年河南省居民营养与健康状况调查中食物摄入量数据,以铅的暂定每周耐受摄入量(PTWI)0.025 mg/kg BW、镉的暂定每月可耐受摄入量(PTMI)25μg/kg BW为参数,对河南省居民膳食中铅、镉暴露水平进行评估。结果河南省居民膳食中铅的平均暴露量为每周0.0086 mg/kg BW,占PTWI的34.4%,MOS值为2.92,贡献率较高的食品种类为面类、蔬菜类和蛋类;镉的平均暴露量为每月9.68μg/kg BW,占PTMI的38.7%,MOS值为2.58,贡献率较高的食品为畜禽肉类、蔬菜类、米类。结论河南省居民膳食中铅、镉的暴露水平均低于暂定可耐受摄入量,但应对铅和镉的主要来源食物开展常规性监测,对可能的高危食品采取必要措施降低污染。
[Abstract]:Objective to evaluate the exposure to lead and cadmium in the diet of the residents of Henan Province, and to understand the intake and harm degree of lead and cadmium in the diet of the residents. Methods the contents of lead and cadmium in 10 kinds of food in Henan Province were monitored from 2013 to 2014. Based on the data of food intake in the 2002 survey of nutritional and health status of Henan Province residents, the lead content in the diet of Henan residents was determined by using the tentative tolerance intake of lead per week (PTWI) 0.025 mg/kg BWW, and the tentative monthly tolerable intake of cadmium (PtMI25 渭 g/kg BW) as parameters. Results the average exposure amount of lead in the diet of Henan residents was 0.0086 mg/kg BW per week, accounting for 34.4% of PTWI and the value of MOS was 2.92. The food with higher contribution rate was noodles, vegetables and eggs. The average exposure amount of cadmium was 9.68 渭 g/kg BW per month, and 38.7% of PTMI was 2.58. The food with higher contribution rate was livestock and poultry meat, vegetables and rice. Conclusion the exposure levels of lead and cadmium in the diet of Henan residents are lower than those of temporary tolerable intake. However, routine monitoring of lead and cadmium sources should be carried out, and necessary measures should be taken to reduce contamination of potentially high risk foods.
