The document represents a brief, quantitatively oriented scientific summary of health effects data. It was developed by the Environmental Criteria and Assessment Office to assist the Office of Emergency and Remedial Response in establishing chemical-specific health-related goals of remedial actions. If applicable, chemical-specific subchronic and chronic toxicity interim acceptable intakes are determined for systemic toxicants, or q(sub 1)* values are determined for carcinogens for both oral and inhalation routes. A q(sub 1)* was determined for polycyclic aromatic hydrocarbons based on both oral and inhalation exposure. These estimates are based on benzo(a)pyrene, the most potent constituent in PAH containing mixtures identified to date. The text provides information concerning the limitations of these estimates.
