Integrating Environmental Justice and the Precautionary Principle in Research and Policy Making: The Case of Ambient Air Toxics Exposures and Health Risks among Schoolchildren in Los Angeles

Abstract

Two policy frameworks, environmental justice and the precautionary principle, have begun to transform traditional approaches to environmental policy making and community organizing related to public health. Despite having several important overlapping policy goals, little effort has been made to purposefully integrate these two frameworks. This article discusses preliminary research on environmental inequality in ambient air toxics exposures and associated health risks among schoolchildren in the Los Angeles Unified School District. Results indicate that children of color, namely, Latinos and African Americans, bear the highest burden of estimated cancer and noncancer health risks associated with ambient air toxics exposures while they are in school. The implications of these study results for controversial policy decisions related to school siting and construction in urban districts are discussed within the context of environmental justice and the precautionary principle.
