摘要

The US EPA is in the process of updating the toxicity information in its IRIS that is greater than 10 years old. The IRIS toxicity values are elements of the risk assessments used to establish exposure limits and cleanup standards at hazardous waste sites. Thus, revisions to these values can have implications for the DoD both in terms of guidance for monitoring human health and occupational exposures as well as the cost of cleanup at ERP sites. To estimate the potential DoD interest in the IRIS chemicals due for updates, the occurrence of these chemicals and their occurrence at ERP sites at concentrations greater than the EPA Region 9 RSLs were evaluated. The 5 IRIS chemicals most frequently noted in HMIRS purchases were ethylbenzene, ethylene glycol, nickel, methanol and manganese. The 5 IRIS chemicals most frequently found at ERP sites at concentrations exceeding the RSLs were arsenic, naphthalene, (benzo a)pyrene, trichloroethylene, and tetrachloroethylene. The ranking of all of the IRIS chemicals due for updating is provided in the report.
