OBJECTIVE
To establish the blood lead concentration and associated risk factors in schoolchildren during 1998 and 2008.
MATERIALS AND METHODS
A blood lead screening was conducted in schoolchildren of 6-12 years of age, enrolled in 17 elementary schools of the metropolitan area of Monterrey, México, during 1998 and 2008.
RESULTS
The mean blood lead level were 9.6 ± 3.0 (µg/dL range of 3.18 to 20.88) in 1998 and 4.5±4.8 µg/dL (range of 3.3 to 53.7) showing a 2.1-times reduction in blood lead levels (p<0.01).
CONCLUSIONS
This reduction in blood lead levels demonstrate environmental and industrial control improvements and the benefits of fading out the leaded gasoline during the 1990's.
目的
确定1998年至2008年期间学童的血铅浓度及相关危险因素。
材料与方法
1998年至2008年期间，对墨西哥蒙特雷大都市区17所小学6至12岁的学童进行了血铅筛查。
结果
1998年平均血铅水平为9.6±3.0（μg/dL，范围为3.18至20.88），2008年为4.5±4.8 μg/dL（范围为3.3至53.7），血铅水平降低了2.1倍（p<0.01）。
结论
血铅水平的这种降低表明环境和工业控制得到改善，以及20世纪90年代无铅汽油逐渐淘汰带来的益处。
