Overview

In November 2019, EPA released the Systematic Review Protocol for the PFBA, PFHxA, PFHxS, PFNA, and PFDA IRIS Assessments for a 45-day public comment period. As part of developing a draft IRIS assessment, EPA presents a methods document, referred to as the protocol, for conducting a chemical-specific systematic review of the available scientific literature. Protocols include strategies for literature searches, criteria for study inclusion or exclusion, considerations for evaluating study methods, information management for extracting data, approaches for synthesis within and across lines of evidence, and methods for derivation of toxicity values.

Background

This protocol includes strategies for literature searches, criteria for study inclusion or exclusion, considerations for evaluating study methods, information management for extracting data, approaches for synthesis within and across lines of evidence, and methods for derivation of toxicity values.

The IRIS Program posts assessment protocols and protocol updates publicly on a chemical’s HERO project page, the IRIS website, and in systematic review repositories such as Zenodo (https://zenodo.org/record/2654896#.XMsScOhKjcs).
