Next, toxicity infomation (Oral RfDs, Inhalation RfCs, and Cancer Toxicity Values) is displayed in tables filled with data from IRIS, PPRTV, ATSDR, CALEPA, and HEAST. Click on any blue toxicity value to see metadata associated with it. The chronic and subchronic values that are used in default PRG equations are highlighted. Metadata is not available for CALEPA values. The last section contains an extensive list of parameters for the chemical followed by tables of parameters from PhysProp, EPI, SSL, CRC, PERRY, LANGE,and YAWS. The value(s) in each table that are highlighted are used in default PRG calculations. Values from other sources are displayed below the output tables. The PRG User's Guide, in section 2.3 and 2.4, presents the toxicity and chemical-specific parameter hierarchies, respectively.
