The analytical problem of measuring total concentrations of organic pollutants in the whole water

The EU Water Framework (2000/60/EC) provides protection from chemical pollutants through the Environmental Quality Standards Directive (2008/105/EC). The Directive is setting environmental quality standards for the priority substances and certain other pollutants according to requirements set in Article 16(8) of the Water Framework Directive. For organic priority substances these Environmental Quality Standards are expressed as total concentrations in the whole water sample. Total concentrations can be obtained by a direct analysis of the whole water sample or by separate determinations on filterable and solid phases. Both solutions have their advantages and drawbacks which are critically discussed in the present review. Analysis of literature data and experiences from standardisation activities shows that there is a possibility to find a simple extraction method for analysing whole water without time consuming separation steps. Membrane disk extraction is now subject to standardization effortsas the most promising technique to achieve this goal. Limitations of this approach are discussed in the light of the consequence on the chemical status assessment.
