Abstract :Specific pollutants are defined as the substances posing a risk on national or river basin level due to being discharged in serious amount according to Water Framework Directive (2000/60/EC) and control of them in surface waters is ensured by the implementation of environmental quality standards (EQS). As a candidate for EU membership, Turkey, has conducted studies on determination of specific pollutants between 2011 and 2015. In this scope, firstly, list of candidate pollutants were prepared based on the field studies, questionnaires and literature surveys. Different prioritization methods were then applied for candidate chemicals considering hazard characteristics, exposure levels and production/use patterns of the substances. Finally, 117 point sourced and 133 non-point sourced specific pollutants were designated with their national EQSs.Keywords : specific pollutants, environmental quality standards, prioritization, hazard characteristics
