Exposure to ambient air pollution and prenatal and early childhood health effects

Health effects model. To estimate exposure to the PM10 produced by our sample plants, we use population data at the survey unit level—that is, at the level of areas geoestadísticas básicas (AGEBs) in Ciudad Juárez and census tracts in El Paso. We assign the inhabitants of each survey unit a distance-weighted average of PM10 concentrations predicted by the ISCST3 model at all model receptor points within 800 meters of the survey unit centroid. Next we estimate the health effects of this exposure using concentration-response (CR) coefficients reported in the epidemiological literature. CR coefficients indicate the expected...
