This study details the first comprehensive evaluation of the efficacy of a soil lead mitigation project in Dong Mai village, Vietnam. The village's population had been subject to severe lead poisoning for at least a decade as a result of informal Used Lead Acid Battery (ULAB) recycling. Between July 2013 to February 2015, Pure Earth and the Centre for Environment and Community Development (Hanoi, Vietnam) implemented a multi-faceted environmental and human health intervention. The intervention consisted of a series of institutional and low-cost engineering controls including the capping of lead contaminated surface soils, cleaning of home interiors, an education campaign and the construction of a work-clothes changing and bathing facility. The mitigation project resulted in substantial declines in human and environmental lead levels. Remediated home yard and garden areas decreased from an average surface soil concentration of 3940 mg/kg to <100 mg/kg. One year after the intervention, blood lead levels in children (<6 years old) were reduced by an average of 67%—from a median of 40.4 μg/dL to 13.3 μg/dL. The Dong Mai project resulted in significantly decreased environmental and biological lead levels demonstrating that low-cost, rapid and well-coordinated interventions could be readily applied elsewhere to significantly reduce preventable human health harm.

通过低成本干预措施减少铅酸电池回收的暴露量来改善人类健康结果:越南同迈

这项研究详细介绍了越南东迈村一项土壤铅减缓项目功效的首次综合评估。由于非正式的废旧铅酸蓄电池(ULAB)回收,该村的居民至少已遭受了严重的铅中毒。从2013年7月到2015年2月,Pure Earth和环境与社区发展中心(越南河内)实施了多方面的环境与人类健康干预措施。干预措施包括一系列机构和低成本的工程控制措施,包括对铅污染的表层土壤进行封盖,居家室内清洁,开展教育运动以及建造工作服更衣和洗浴设施。缓解项目导致人员和环境铅水平大幅下降。修复后的家庭庭院和花园区域的平均表层土壤浓度从3940 mg / kg降至<100 mg / kg。干预一年后,儿童(<6岁)的血铅水平平均降低了67%,从中位数40.4μg/ dL降至13.3μg/ dL。Dong Mai项目导致环境和生物铅水平大大降低,表明低成本,快速和协调良好的干预措施可以很容易地应用于其他地方,以大大减少可预防的人类健康危害。
