Toxicological and Health Professionals

Health Professional with book

This section provides technical information to scientists and public health and medical professionals on the effects of hazardous substances. This information includes health effects and health guidance values, the potential for exposure, analysis, regulations, data needs, comprehensive references, a priority list, and more.

Resources for Toxicological and Health Professionals
  • Toxicological Profiles - Succinctly characterize the toxicologic and adverse health effects information for a hazardous substance.
  • ToxGuides - Quick reference guide providing information such as chemical and physical properties, sources of exposure, routes of exposure, minimal risk levels, children's health, and health effects for a substance.
  • Priority List of Hazardous Substances - Prioritization of substances based on a combination of their frequency, toxicity, and potential for human exposure at National Priorities List (NPL) sites.
  • Minimal Risk Levels (MRL) - The MRL is an estimate of the daily human exposure to a hazardous substance that is likely to be without appreciable risk of adverse, non-cancer health effects over a specified duration of exposure. The information in this MRL serves as a screening tool to help public health professionals decide where to look more closely to evaluate possible risk of adverse health effects from human exposure.
  • Framework for Assessing Health Impacts of Multiple Chemicals and Other Stressors - Provides guidance for assessment of joint toxicity of environmental chemicals to determine whether exposure to chemical mixtures may impact public health.
  • Interaction Profiles - Succinctly characterizes the toxicologic and adverse health effects information for mixtures of hazardous substances.
  • Priority Data Needs - The priority data needs represent essential information to improve the database for conducting public health assessments.
