On August 22, 2017 the European Chemicals Agency (ECHA) will hold a workshop on applications for authorization of environmental endocrine disrupting chemicals (EDCs) under REACH in Brussels, Belgium. In June 2017, the European Commission (EC) added two substances of very high concern (SVHCs) to the Authorisation List (Annex XIV) of REACH due to their endocrine disrupting properties for the environment: 4-(1,1,3,3-Tetramethylbutyl)phenol, ethoxylated (no CAS number available) and 4-nonylphenol, branched and linear, ethoxylated (no CAS number available) (FPF reported). “There is scientific uncertainty surrounding whether or not thresholds can be derived for endocrine disrupting (ED) substances,” ECHA explained. During the workshop, stakeholders and ECHA will exchange views “on the available scientific evidence relating to the hazard, risk and impact assessment” of the two substances to “explore potential ways forward in applications for authorization.” In particular, the workshop will address “whether it is possible to derive thresholds or dose-response relationships for these substances.”

The workshop is free of charge. Spaces are limited and registration is open until August 2, 2017. If technically feasible, the workshop will be web streamed; presentations will be made available after the event.
