Last night, Environmental Defense Fund (EDF) submitted critical comments on EPA’s Office of Pollution Prevention and Toxics’ (OPPT) “systematic review” document that OPPT is using to evaluate chemicals’ risks under the Toxic Substances Control Act (TSCA).
Systematic review, a hallmark of the clinical sciences, employs structured approaches to identifying, evaluating, and integrating evidence in a manner that promotes scientific rigor, consistency, transparency, objectivity, and reduction of bias.
Unfortunately, OPPT’s systematic review document deviates dramatically from the best practices in systematic review—practices developed over decades based on empirical evidence and experience in application. OPPT’s approach also significantly diverges from recent recommendations of the National Academy of Sciences (see here and here).
