Toxicological and Health Professionals

Health Professional with book

The ATSDR Public Health Statements (PHSs) listed below are a series of summaries about hazardous substances. The information in these PHSs was taken from Chapter One of their respective ATSDR Toxicological Profiles. However, PHSs have been discontinued and replaced with our shorter, more popular version of the PHSs, called the ToxFAQs™. See the ToxFAQs™ home page.

Resources for Toxicological and Health Professionals
  • Toxicological Profile - Succinctly characterize the toxicologic and adverse health effects information for a hazardous substance.
  • Addendum to the Profile - The purpose of Toxicological Profiles Addenda is to provide, to the public and other federal, state, and local agencies a non-peer reviewed supplement of the scientific data that were published in the open peer-reviewed literature since the release of the profile.
  • ToxGuide - 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.
  • Substance Priority List - 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.
