Scientific opinion on "Draft environmental quality standards for priority substances under the Water Framework Directive" : HBCDD

The dossier on Environmental Quality Standards for "HBCDD" is evaluated by the SCHEER according to the general mandate on EQS dossiers. However, in the case of HBCDD, the SCHEER was asked specifically to evaluate only the revision of the QSs that relate to secondary poisoning of top predators (QSsecpois, biota) and to human health due to food uptake (QSbiota, hh). The SCHEER therefore did not evaluate other QSs in the Dossier. Those other QSs were evaluated in 2011. The SCHEER recommends to update the other QSs because many new data on the aquatic toxicity of HBCDD have become available in the period 2011-2022.
