目的了解广州市0~6岁儿童铅血水平,为制定干预对策提供依据。方法选择2015年1月-2017年5月在广东省妇幼保健院儿童保健门诊体检的14 970名0~6岁健康儿童为研究对象;统一采用钨舟型原子吸收光谱仪检测血铅水平。结果 14 970例0~6岁儿童总体血铅平均水平为(32.5±19.3)μg/L(1.4~319.0μg/L);高铅血症(血铅≥100μg/L)检出率为0.8%;男童血铅水平(33.0±19.3)μg/L高于女童(31.7±19.2)μg/L;儿童血铅水平随年龄增加而升高,0岁组婴儿血铅水平为(29.3±18.3)μg/L,6岁组儿童血铅水平为(37.1±17.8)μg/L。结论广州市儿童血铅水平和高血铅检出率处于较低水平,儿童血铅水平随年龄增加呈逐渐上升趋势,提示需定期开展儿童血铅水平监测。
Objective To understand the level of lead in 0 ~ 6 years old children in Guangzhou and provide the basis for making intervention measures. Methods From January 2015 to May 2017, 14 970 healthy children aged 0-6 years old from the health check-up of MCH in Guangdong MCH hospital were selected as research objects. Blood lead levels were determined by T-wave atomic absorption spectrometry. Results The average level of blood lead in 14 970 children aged 0-6 years was (32.5 ± 19.3) μg / L (1.4 ~ 319.0 μg / L). The detection rate of hyperlipidemia (blood lead ≥100 μg / L) was 0.8% (33.0 ± 19.3) μg / L in boys was higher than that in girls (31.7 ± 19.2) μg / L; the level of blood lead in children increased with age, the level of blood lead in the 0-year-old group was (29.3 ± 18.3) μg / L. The level of blood lead in the 6-year-old children was (37.1 ± 17.8) μg / L. Conclusions The level of blood lead and the detection rate of high blood lead in children in Guangzhou are at a low level. The level of blood lead in children is gradually increasing with the increase of age, which indicates that the level of blood lead in children should be regularly monitored.
