了解和评估江苏省不同年龄组儿童铅膳食暴露情况。通过整合2002年江苏地区3～12岁儿童24h膳食回顾资料和2001—2006年江苏省农产品铅污染监测数据,计算江苏不同年龄组(3～,6～,9～12岁)儿童膳食铅摄入量,与FAO/WHO推荐的铅暂定每周可耐受摄入量(PTWI,25μg/kg)比较,评价其危险性。江苏各年龄组儿童每周膳食铅暴露量中位数范围为9.0～11.7μg/kg,各年龄组膳食铅摄入量统计量随年龄增加而下降,组间差异有统计学意义(P<0.01)。各年龄组95%以上儿童每周膳食铅摄入量低于PTWI。
Understand and evaluate lead dietary exposure among children of different ages in Jiangsu Province. The dietary lead intake of children of different ages (3 ~ 6 ~ 9 ~ 12 years old) in Jiangsu Province was calculated by integrating the data of 24-hour dietary recall of children aged 3 ~ 12 in Jiangsu Province in 2002 with the monitoring data of lead pollution of agricultural products in Jiangsu Province from 2001 to 2006. , And compared with the tentative weekly tolerable intake of lead (PTWI, 25 μg / kg) recommended by FAO / WHO to evaluate the risk. The weekly dietary lead exposure of children of all age groups in Jiangsu ranged from 9.0 to 11.7 μg / kg, and the dietary lead intake statistic of all age groups decreased with increasing age with statistical significance (P <0.01 ). Over 95% of children in each age group have lower weekly dietary lead intake than PTWI.
