目的 评价铅对作业工人子代健康的影响。方法 选择父亲和 (或 )母亲从事铅作业的 14 7名城区儿童 ( 6～10岁 )为接触组 ,父母亲均不接触铅及其它化学毒物的儿童 99名为对照组。测定两组儿童身高、体重、胸围、发铅、血铅、血锌卟啉及智商和部分血液指标。结果 接触组发铅、血铅、血锌卟啉明显高于对照组 (P <0 0 1) ,血红蛋白、红细胞数明显低于对照组 (P <0 0 1) ,女性胸围发育明显落后于对照组 (P <0 0 1) ;上述改变以父亲母亲同时接触铅影响最大、父亲接触铅次之、母亲接触铅影响最小。结论 职业接触铅对子代健康有不良影响
Objective To evaluate the impact of lead on the health of working-class children. Methods A total of 147 children (6 ~ 10 years old) in urban areas who were working on lead by their father and / or mother were selected as the control group. There were 99 children who did not contact with lead and other chemical toxicants in the contact group. The children’s height, weight, bust, hair lead, blood lead, blood zinc porphyrin, IQ and some blood indexes were measured. Results The levels of lead, blood lead and blood zinc porphyrin in the exposed group were significantly higher than those in the control group (P <0.01), and the hemoglobin and erythrocyte numbers in the exposure group were significantly lower than those in the control group (P <0.01) Group (P <0.01). The above changes had the greatest impact on the lead exposure of father and mother at the same time. The father had the highest exposure to lead and the mother had the least impact on lead exposure. Conclusion Occupational exposure to lead has adverse effects on the health of offspring
