Childhood Lead Poisoning: A Perpetual Environmental Justice Issue?

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.
