Abstract

This chapter discusses the environmental protection agency (EPA) screening levels and pesticides status. The US EPA developed regional screening levels (RSLs) for the Superfund/RCRA programs. RSLs are risk-based concentrations, derived from standardized equations combining exposure information assumptions with US EPA toxicity data. They are considered by the Agency to be protective for humans (including sensitive groups), over a lifetime. The RSLs contained in the table are generic. They are calculated without site-specific information. They may be re-calculated using site-specific data. These three categories are labeled as EPA Re-registration Status, EPA Maximum Residue Limit Exists, and Pesticide or Intermediate. EPA Re-registration Status refers to those pesticides whose Maximum Residue Limits have been reassessed and accepted under the new standards set by the 1996 Food Quality Protection Act.
