Detection and Analysis of Children's Blood Lead Concentration in Mianyang from 2010 to 2012

目的:了解绵阳市儿童血铅水平,为儿童铅中毒防治提供科学依据。方法采用原子吸收光谱法对到绵阳市中心医院532名0~14岁儿童的静脉血进行检测分析。结果儿童血铅均值为36.92μg/L,铅中毒率为2.07%。男性儿童和女性儿童的血铅均值分别为37.67μg/L和35.81μg/L。0~3岁组、4~6岁组和7~12岁组血铅均值分别为33.62μg/L、35.65μg/L 、38.39μg/L,中毒率分别为1.49%、1.98%和2.28%,血铅水平和中毒率随着年龄增长均有增高趋势,但差异无统计学意义。结论绵阳市儿童血铅浓度底于全国平均水平,铅中毒率较底。

Objective To understand the children's blood lead concentration in Mianyang and provide scientific measures for preventing children lead poisoning.Methods 542 children's venous bloods of aged from 0 to 14 years old were col ected and detected by atomic absorption spectrometry method.Results the geometric means of blood lead levels of children was 36.92μg/L,blood lead poisoning rates was 2.07%.The average blood lead in boys and girls was 37.67μg/L and 35.81μg/L respectively.The average blood lead in 0~3 years group,4~6 years group,7~12 years group was 33.62μg/L,35.65μg/L,and 38.39μg/L;the lead poisoning rates in the three groups was 1.49%、1.98%and 2.28%respectively.The blood lead levels and the lead poisoning rate increased with age,while there is not significant dif erence in these groups.Conclusions The blood lead levels and the lead poisoning rate in Mianyang was relatively lower than the national average.
