Concentrations of single BDE congeners are declining, but the availability of long time series is limited in the Baltic Sea and concentrated in the western parts of the region.
The confidence of the indicator evaluation is high.
The indicator is applicable in the waters of all countries bordering the Baltic Sea.
Polybrominated diphenyl ethers (PBDEs) are toxic and persistent substances that bioaccumulate in the marine foodweb. Increasing concentrations of PBDEs were detected in the environment in past decades as their use as commercial flame retardants increased. The use of most PBDE products have been banned in Europe during the last 10 years, and as a result decreasing concentrations are detected for some of the BDE congeners.
Concentrations of hazardous substances close to natural levels
D8 Concentrations of contaminants
D8C1 Within coastal and territorial waters and beyond territorial waters the concentrations of contaminants do not exceed the threshold value
Fish safe to eat
D9 Contaminants in fish and seafood
D9C1 The level of contaminants in edible tissues (muscle, liver, roe, flesh or other soft parts, as appropriate) of seafood (including fish, crustaceans, molluscs, echinoderms, seaweed and other marine plants) caught or harvested in the wild (exclusing fin-sih from mariculture) does not exceed the threshold value
