IRIS Toxicological Review of Diisobutyl Phthalate (Dibp) (Preliminary Assessment Materials)

Abstract

In September 2014, EPA released the draft literature searches and associated search strategies, evidence tables, and exposure response arrays for DIBP to obtain input from stakeholders and the public prior to developing the draft IRIS assessment. Specifically, EPA was interested in comments on the following:

• Draft literature search strategies
• The approach for identifying studies
• The screening process for selecting pertinent studies
• The resulting list of pertinent studies
• Preliminary evidence tables
  • The process for selecting studies to include in evidence tables
  • The quality of the studies in the evidence tables

The literature search strategy, which describes the processes for identifying scientific literature, contains the studies that EPA considered and selected to include in the evidence tables. The preliminary evidence tables and exposure-response arrays present the key study data in a standardized format. The evidence tables summarize the available critical scientific literature. The exposure-response figures provide a graphical representation of the responses at different levels of exposure for each study in the evidence table.

Impact/Purpose

The purpose of this document is to distribute preliminary materials for diisobutyl phthalate (DIBP). This information is distributed solely for the purpose of pre-dissemination review under applicable information quality guidelines. These preliminary materials include a planning and scoping summary, information on the approaches used to identify pertinent literature, results of the literature search, approaches for selection of studies for hazard identification, presentation of critical studies in evidence tables and exposure-response arrays, and mechanistic information for DIBP. These preliminary materials are being circulated for review of its technical accuracy and science policy implications. These materials will be posted on the EPA website to make them available to the public.
