在波兰一项预防儿童铅中毒的项目中,研究者分析了11,877名年龄在24~84个月儿童的记录,评估了不同取样季节儿童的铅暴露与血铅水平的关系、问卷数据和环境铅水平。作为周围环境空气检测系统指标的空气中铅浓度和铅沉降微尘是低于当前波兰的空气质量标准的,并且在逐渐下降。血铅水平的几何均数是63μg/L(范围在6~480μg/L),>13%的儿童血铅水平>100μg/L。平均血铅水平从1993~1994年的68μg/L下降到1998年的55μg/L。尽管空气中铅浓度在春夏季节(非采暖的季节)低秋冬季节(采暖的季节)高,但是在春夏季节血铅水平的几何均数比秋冬季节的高10%,在采暖和非采暖季节平均血铅水平都随着空气中铅浓度的增加而显著增加。贫穷的住房条件、家庭中有2个或更多的兄弟姐妹、去外地进行娱乐性旅行的缺乏、儿童户外活动时间与血铅水平的增加相关联。西里西亚地区儿童铅暴露研究的结果可用于建议和改善制定儿童铅暴露风险的标准以便于采取更有效的预防措施。
In a project to prevent childhood lead poisoning in Poland, the researchers analyzed 11,877 children aged 24-84 months and assessed the relationship between lead exposure and blood lead levels in children of different sample seasons. The questionnaire data and environmental lead Level. Airborne lead concentrations and plumb deposition dust, which are indicators of ambient air testing systems, are below the current air quality standards in Poland and are declining. The geometric mean blood lead levels were 63 μg / L (range 6 to 480 μg / L), and blood lead levels> 100 μg / L for> 13% of children. The average blood lead level dropped from 68 μg / L in 1993-1994 to 55 μg / L in 1998. Although the concentration of lead in the air is high in the low-fall winter season (heating season) in the spring-summer season (non-heating season), the geometric mean blood lead level in spring and summer is 10% higher than in the autumn-winter season, The mean seasonal blood lead levels increased significantly with increasing concentrations of lead in the air. Poor housing conditions with two or more siblings in the family, the absence of entertaining trips to the field, and children’s outdoor time associated with an increase in blood lead levels. The results of a study on lead exposure in children in the Silesia region can be used to recommend and improve the criteria for establishing the risk of lead exposure in children so that more effective prevention measures can be taken.
