杭州市3528例儿童血铅水平调查

Investigation on blood lead levels of 3 528 children in Hangzhou city

目的:了解杭州市10岁以下儿童血铅水平及高血铅检出率。方法:用原子吸收光谱分析法对3 528例儿童进行血铅含量测定,比较不同性别和年龄组之间的差异。结果:3 528例儿童血铅平均值为24.91μg/L,其中>100μg/L有37例,占1.04%;不同性别儿童间血铅水平几何均值差异有统讲学意义,而高血铅检出率差异无统计学意义;不同年龄儿童的血铅水平几何均值差异无统计学意义,高血铅检出率有统计学差异。结论:杭州市儿童血铅水平较低,但铅中毒情况依然存在,应采取进一步措施减少儿童铅接触。

Objective： To understand the blood lead levels and detection rate of lead poison among children under ten years in Hangzhou city. Methods： Atomic absorption spectrochemical analysis was used to detect blood lead contents of 3 528 children, the differ- ences of blood lead content among children of different genders and children in different age groups were compared. Results： The mean val- ue of blood lead in 3 528 children was 24. 91 μg/L, the blood lead levels of 37 children were more than 100 μg/L, accounting for 1.04% ; there was statistically significant difference in geometric mean value of blood lead between boys and girls, but there was no statistically signifi- cant difference in detection rate of lead poison between boys and girls ; there was statistically significant difference in geometric mean value of blood lead among children in different age groups, but there was statistically significant difference in detection rate of lead poison among chil- dren in different age groups. Conclusion ： The blood lead levels of children in Hangzhou city is relatively low, but lead poisoning still ex- ists, further measures should be taken to reduce lead exposure in children.
