The effect of abating soil lead was assessed among Baltimore children. The hypothesis was that a reduction of 1000 parts per million would reduce children's blood lead levels by 0.14 to 0.29 mumol/L (3-6 micrograms/dL).
In 2 neighborhoods (study and control), 187 children completed the protocol. In the study area, contaminated soil was replaced with clean soil.
Soil lead abatement in this study did not lower children's blood lead.
Although it did not show an effect in this study, soil lead abatement may be useful in certain areas.
评估巴尔的摩儿童中减少土壤铅含量的效果。假设是百万分之一千的铅含量降低会使儿童血铅水平降低0.14至0.29微摩尔/升(3 - 6微克/分升)。
在2个社区(研究组和对照组),187名儿童完成了该方案。在研究区域,用清洁土壤替换受污染土壤。
本研究中减少土壤铅含量并未降低儿童血铅水平。
尽管在本研究中未显示出效果,但减少土壤铅含量在某些地区可能有用。
