摘要
目的了解泰安市城乡7～12岁学龄儿童血铅水平,探讨低水平铅暴露对儿童健康的影响方法采用原子吸收法测血铅含量;对其中40例高血铅(≥100μg/L)、60例低水平铅暴露者(30～99μg/L)进行临床表现调查与部分血液指标检测,Conners父母量表评定行为问题,且与正常者比较。结果高血铅检出率为4.25%;低水平铅暴露检出率为7.25%。儿童男女性别间差异无显著性,但随着年龄的增长血铅水平增高的比例明显上升。高血铅组、低水平铅暴露组头痛、食欲减退、反复呼吸道感染、脾气急躁、注意力不集中和腹痛的发生率均高于对照组;平均红细胞容积、平均红细胞血红蛋白量均低于对照组,差异有显著性(P<0.05),但前两组在这些症状方面差异无统计学意义(P>0.05)。结论7～12岁学龄儿童的血铅水平高的比例随年龄增长而增加,高血铅、低水平铅暴露对儿童的健康都产生负性影响。
Ohjective ： To investigate the blood lead level and the effect of low-level lead exposure on school children＇ s health in both urban and rural regions of Taian City, Shandong province. Methods ： Blood lead was determined by the method of atom absorption. Among them we investigated 40 high blood lead pupils and 60 low-level lead exposure pupils clinically and detected part of the blood index, then we compared those with 40 normal group. The behaviors of children were assessed with Conners＇ Rating Scale. Results： The rate of high blood lead measured was 4.25% and the rate of low-level lead exposure measured was 7.25%. Regression and correlation analysis showed that there was no significant difference between males and females. But there was a significant difference in morbidity rate of children＇s blood lead level increase in the different age groups. The symptoms, like headache, anorexia, repeated infection of respiratory tract, bad temper and lack of concentration in both high blood lead groups and low-levels lead exposure groups occurred more frequently than those in the normal groups ; Both MCV and MCH were all lower than those in the normal groups （ P 〈 0.05）. But there was no significant difference between the former two groups（ P 〉 0.05 ）. Conclusion： The percentage of high blood lead pupils increases with the age growth in 7 - 12 years old group, and the health of children with high blood lead and low-levels lead exposure has been affected.
