目的:了解兰州市儿童铅中毒患病情况,提出预防措施。方法:用石墨炉原子吸收光谱法,对兰州市妇幼保健院儿童保健科正常体检的2 705例0~6岁儿童进行血铅检测。结果:2 705例儿童中,铅中毒(血铅浓度≥100μg/L)的检出率为57.1%,男性高于女性(P=0.000);年龄越大,检出率越高(P=0.000);检出率在春秋季高于冬夏季节(P=0.016<0.05)。结论:兰州市0~6岁儿保门诊体检儿童铅中毒的检出率较高,男性高于女性,年龄越大,检出率越高,春秋季是铅中毒的高发季节,应予以足够重视,采取适当措施,防治铅中毒。
Objective: To understand the prevalence of lead poisoning in children in Lanzhou and to put forward preventive measures. Methods: Blood samples were collected from 2 705 children (0-6 years old) undergoing physical examinations in Lanzhou MCH center by graphite furnace atomic absorption spectrometry. Results: Among 2 705 children, the detection rate of lead poisoning (blood lead concentration ≥100μg / L) was 57.1%, higher in males than in females (P = 0.000). The older the detection rate was (P = 0.000 ). The detection rate was higher in spring and autumn than in winter and summer (P = 0.016 <0.05). Conclusion: The detection rate of lead poisoning in children aged 0 ~ 6 years in Lanzhou was higher than that in males. The older the rate was, the higher the detection rate was. Spring and autumn were the high incidence of lead poisoning and should be given enough attention , Take appropriate measures to prevent lead poisoning.
