This core indicator evaluates the status of the marine environment based on concentrations of hexabromocyclododecane (HBCDD) in Baltic Sea fish. Quantitative threshold values are used to classify core indicators status in "Fail", "Achieve" or "Not assessed". The threshold value is an environmental quality standard (EQS), derived at EU level as a substance included on the priority list under Directive 2008/105/EC. This dataset displays the result of the indicator in HELCOM Assessment Scale 4 (Division of the Baltic Sea into 17 sub-basins and further division into coastal and off-shore areas and division of the coastal areas by WFD water types or water bodies).

This core indicator evaluates the status of the marine environment based on concentrations of the tributyltin (TBT) and its breakdown products dibutyltin (DBT) and monobutyltin (MBT) in the Baltic Sea; in water, biota (mussels, marine gastropods) and sediments. Imposex effects of TBT on marine gastropods are used as another source of data on TBT. Quantitative thresholds are used to classify core indicators status in "Achieve", "Fail" or "Not assessed". Good status is achieved when the concentrations of TBT are below the threshold value. This dataset displays the result of the indicator in HELCOM Assessment Scale 4 (Division of the Baltic Sea into 17 sub-basins and further division into coastal and off-shore areas and division of the coastal areas by WFD water types or water bodies).

The objective of the BALTHAZAR project has been to assess the potential sources of hazardous substances from landfills/dumping sites, to characterise their environmental risks and to develop measures to reduce the risks of run-off of hazardous substances from waste site to the Baltic Sea.

This core indicator evaluates the status of the marine environment based on concentrations of Polyaromatic hydrocarbons (PAH) metabolites in biota. Quantitative threshold value is used to classify core indicators status in “Achieve”, “Fail” or “Not assessed”. As There is no commonly agreed threshold value for measuring metabolites available, this report only considers concentrations of contaminants.
