目的了解胜利油田儿童血铅水平及铅中毒的年龄、性别、地域分布特点。方法采用分层整群随机抽样的方法,对胜利油田2~13岁3419名儿童进行末梢血铅含量的测定。结果胜利油田2~13岁儿童血铅水平均值为57.54μg/L,血铅值≥100μg/L者为13.02%,血铅值≥200μg/L者为1.14%。胜利油田中心城区儿童血铅平均值为58.69μg/L,明显高于生活区和远郊地区。随着年龄的增长,血铅水平及铅中毒检出率呈上升趋势。男童血铅平均值60.85μg/L明显高于女童血铅平均值53.75μg/L(p<0.01)。结论(1)与国内外相关报道资料相比,胜利油田2~13岁儿童的平均血铅水平及铅中毒检出率均较低。(2)儿童血铅水平存在明显的性别差异、年龄差异和地域差异。
Objective To understand the age, sex and geographical distribution of blood lead levels and lead poisoning in children in Shengli Oilfield. Methods Stratified cluster random sampling method was used to determine the peripheral blood lead levels in 3419 children aged 2 ~ 13 years old in Shengli Oilfield. Results The average level of blood lead in children aged 2-13 years in Shengli Oilfield was 57.54μg / L, that of blood lead level ≥100μg / L was 13.02%, and that of blood lead level ≥200μg / L was 1.14%. The average blood lead level of children in downtown of Shengli Oilfield was 58.69μg / L, which was significantly higher than that of living area and outer suburbs. With age, blood lead levels and lead poisoning detection rate is on the rise. The average blood lead level of boys was 60.85μg / L, which was significantly higher than that of girls’ average blood lead level of 53.75μg / L (p <0.01). Conclusions (1) Compared with the domestic and international reports, the average blood lead level and lead poisoning rate of children aged 2-13 in Shengli Oilfield are both lower. (2) Children’s blood lead levels have obvious gender differences, age differences and geographical differences.
