What about Environmental Quality Standards for PBDEs in European river biota?

Flame retardants (FRs) are widely used to increase the fire resistant of some materials. One of the most widely used FRs were polybromodiphenyl ethers (PBDEs). These compounds have a high lipophilicity and therefore they can be bioaccumulated and biomagnified along the food chain. Moreover, several toxic properties have been reported for PBDEs: they can act as endocrine disruptors and affect neurological, thyroid and liver activity. As a result in 2009 the Stockholm Convention decided to add the commercial mixtures with four, five, six and seven bromines to the Annex A, to end their production and use [1].
