Contents Notes |
This report, prepared for the Office of Emergency and Remedial Response (OERR) of the Environmental Protection Agency, recommends modifications to the toxicity factor of the EPA Hazard Ranking System (HRS) that incorporate: (1) an assessment of the capacity of a substance to cause short- or long-term adverse effects, cancer, birth defects, or changes in genetic material; (2) a more accurate assessment of the potential hazard of substances by considering the toxicity of each substance for each expected mode of exposure to humans; and (3) more discrimination in the ranking of toxic substances and waste sites. This report critiques the current HRS toxicity factor and eight other ranking systems selected as representative of the methodologies used to discern the relative dangers of substances. This report then presents the rationale and derivation of the suggested modifications to the HRS toxicity factor and presents the evaluation of 30 substances found at National Priorities List (NPL) sites as examples of the proposed scoring methodology. |
