The relevance of European Biota Quality Standards on the ecological water quality as determined by the multimetric macro-invertebrate index : a Flemish case study
Abstract: European Biota Quality Standards (EQSbiota), for compounds with low water solubility and high biomagnification, were created to sustain water quality and protect top predators and humans from secondary poisoning. In reality, for multiple compounds, an exceedance of these standards is often...

Accumulated perfluoroctane sulfonate (PFOS), mercury (Hg), hexabromocyclododecane (HBCD), polybrominated diphenyl ethers (PBDEs), dioxins and polychlorinated biphenyls (PCBs) concentrations were measured in muscle tissue of European yellow eel (Anguilla anguilla) and perch (Perca fluviatilis).

The lack of a significant regression model for the other compounds indicated an effective threshold value higher than the concentrations measured in the present study.
