Dependence of intake fraction on release location in a multi-media framework: A case study of four contaminants in North America (original) (raw)

2003, Lawrence Berkeley National Laboratory

AI-generated Abstract

This research investigates the dependence of intake fraction (iF) on the release location of contaminants using a multi-media framework, focusing on the influence of emission locations relative to population density and food production areas in North America. The study employs the BETR North America contaminant fate model applied to four chemicals: benzene, carbon tetrachloride, benzo[a]pyrene, and TCDD, revealing that while average parameters provide decent estimations, variability can be significant, underscoring the importance of spatial considerations in exposure assessments. It advocates for improved models and monitoring to better understand the public health implications of chemical emissions.
