Overview of available chemical analytical screening methods for identification of pollutants in European waters

Abstract : The need for collection and dissemination of information about the currently applied techniques for analytical screening of chemical pollutants in water has been recognized at European level. These techniques are identified as promising tools for the identification of the pollutants of concern at river basin or local level (river basin specific pollutants) under the Water Framework Directive WFD (2000/60/EC)). They should allow a cost effective overview of the pollutants in the aquatic environment, in preparation of dedicated monitoring programmes. The Italian Institute for Water Research IRSA, the EC Joint Research Centre and the NORMAN Association (Network of reference laboratories and research centres for emerging pollutants www.norman-network.net) for emerging pollutants have launched a survey for identification of currently available and used screening methods for the identification and quantification of chemical contaminants in water. A questionnaire was sent to the delegates of the chemical monitoring group under the Water Framework Directive Common Implementation Strategy (WFD - CIS) and through the NORMAN network. 20 compiled questionnaires were received. The response covered a wide geographical spread, including UK, Ireland, Portugal, Spain, France, Switzerland, Austria, Germany, The Netherlands, Denmark, Czech Republic and the Slovak Republic. The survey included questions about the scope of currently employed screening techniques, the instrumental approach and the validation scheme as well as method performance information and target compounds or compound classes. The reported methodologies include multiresidue methods with a defined target compound list, suspect screening techniques without reference standards (i.e. methods which are based on a mass spectra library with a large set of compounds or compound groups) and non-target screening approaches which include the identification of unknown compounds. A wide range and number of chemical pollutants can be covered by the use of liquid chromatography and gas chromatography coupled with mass spectrometer detectors. Methods are in most cases developed and validated in-house. Some of the methodologies are currently in use for monitoring programmes related to the implementation of the WFD. The survey shows that a common understanding of definitions and scopes is essential in exchanging information about most efficient approaches for target, suspect and non-target screening.
