As the amount of lead in the environment has significantly decreased with the removal of lead in gasoline and paint, the United States has made great strides in preventing lead poisoning or reducing levels of lead in young children's blood. Even so, lead exposure is not equal for all children-low-income and minority children continue to bear a disproportionate burden of exposure primarily through contact with deteriorating lead-based paint from older housing and potentially through drinking contaminated water resulting from failing leaded pipes, as evidenced by the recent events in Flint, Michigan. These facts suggest that childhood lead poisoning is an environmental justice issue worthy of public health consideration and action; "environmental justice" is focused on identifying and addressing disproportionately high and adverse effects of environmental hazards on low-income and minority communities. The question remains, however, as to whether addressing the quality-of-life "risk" factors associated with lead poisoning might eventually lead to reduction in exposure, as well as potentially resulting in adverse health effects. Utilizing an environmental justice framework and examining this issue through a multidimensional environmental justice lens, we contemplated the quality-of-life factors that may essentially predispose minority children and their families to lead poisoning. Specifically, we examined American Community Survey data (2012-2016) focused on comparing race/ethnicity with other sociodemographic variables known to be associated with risks for childhood lead poisoning. The results provide thought-provoking context for making progress toward eliminating lead poisoning as a major environmental justice concern.
随着环境中铅含量的显著降低,美国在防止铅中毒或降低幼儿血液中铅含量方面取得了重大进展。尽管如此,并非所有儿童都面临同样程度的铅暴露——低收入和少数族裔儿童仍然承受着不成比例的暴露负担,主要是通过接触旧住房中不断恶化的含铅油漆,以及可能通过饮用因铅管失效而受到污染的水,密歇根州弗林特市最近发生的事件就证明了这一点。这些事实表明,儿童铅中毒是一个值得公共卫生关注和采取行动的环境正义问题;“环境正义”的重点是确定和解决环境危害对低收入和少数族裔社区的不成比例的高影响和不利影响。然而,仍存在一个问题,即解决与铅中毒相关的生活质量“风险”因素是否最终会导致接触减少,并可能导致不良健康影响。利用环境正义框架,并通过多维环境正义视角来审视这个问题,我们考虑了可能使少数族裔儿童及其家庭易患铅中毒的生活质量因素。具体来说,我们检查了美国社区调查数据(2012-2016 年),重点比较了种族/族裔与其他已知与儿童铅中毒风险相关的社会人口统计学变量。研究结果为消除铅中毒作为一个主要的环境正义问题提供了发人深省的背景。
