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.
