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 level of blood lead and the detection rate of high blood lead in children under 10 in Hangzhou. Methods: The blood lead levels of 3 528 children were determined by atomic absorption spectrometry. The differences between different sexes and age groups were compared. Results: The average blood lead level of 3 528 children was 24.91μg / L, of which 37 cases were> 100μg / L, accounting for 1.04%. The difference of geometric mean blood lead levels between different sexes had the meaning of lecture, No significant difference in the rate of blood lead levels in children of different ages geometric mean difference was not statistically significant, high blood lead detection rate was statistically different. Conclusion: The level of blood lead in children in Hangzhou is low, but lead poisoning still exists. Further measures should be taken to reduce lead exposure in children.
