This document presents a "priority list of substances for further evaluation of their role in endocrine disruption. During 2000, a candidate list of 553 man-made substances and 9 synthetic/natural hormones has been identified."

Category included on the Endocrine Disruptor Liist
Synthetic pyrethroids While only the broad category "Synthetic pyrethroids" was included in the Commission's list, it might be of some interest to note that the following organofluorine pesticides are "Synthetic pyrethroids:" Acrinathrin, Bifenthrin, beta-Cyfluthrin, Cyhalothrin, gamma-Cyhalothrin, lambda-Cyhalothrin, Fenfluthrin, Flucythrinate, Flufenprox, Flumethrin, Fluvalinate, tau-Fluvalinate, Halfenprox, Protrifenbute, Silafluofen, Tefluthrin, Transfluthrin
