The “NJDEP Division of Air Quality Risk Screening Worksheet for Long-Term Carcinogenic and Noncarcinogenic Effects and Short-Term Effects” has been updated with a number of new toxicity values.  The specific changes are summarized in “Revisions to the NJDEP/DAQ Risk Screening Worksheet.”  Toxicity values and their references are listed in the following documents: 1) Unit Risk Factors for Inhalation, 2) Reference Concentrations for Inhalation, and 3) Reference Concentrations for Short-Term Inhalation Exposure.   The updated toxicity values are primarily based on current guidance from the California Office of Environmental Health Hazard Assessment and the USEPA Integrated Risk Information System.
