Abstract
BACKGROUND: Lead poisoning can severely affect neurological development in small children. Communities with environmental justice concerns often face higher levels of lead exposure via multiple routes of exposure. School-aged children can be exposed to lead at their schools through the deposition of lead emissions onto soil over time. METHOD: Public school students' demographics in 'proximate schools;' those within 1.5 km of facilities with lead emissions were compared to other schools in their area. The average proximate emissions per student were calculated for different demographic groups in various geographic areas. RESULTS: Schools in combined statistical areas within 1.5 km of lead facilities were found to be composed of significantly more Black (22%) and Hispanic (30%) students than other schools in the area (17% and 26% respectively). Meanwhile, schools close to lead sources tended to have smaller proportions of white students (37% in 'proximate schools', but 47% overall. When average emissions around students were calculated for a handful of combined statistical areas, inequality in lead exposure could be seen in almost every geographic area, across income and racial lines. DISCUSSION: Students of color consistently faced the highest emissions in every area, though amounts, inequities, and at-risk populations differed throughout the different geographic areas. CONCLUSION: The unique history of each location regarding immigration, discrimination, zoning laws, urban sprawl, and industrial past can contribute to this variety in inequities. These findings are not only consistent with environmental justice trends but also highlight other vulnerabilities for students like age and food security.
