Since the analytical approach is quite different for these substances, different laborato 
ries have been involved according to their analytical specialities. Chlorinated paraffins 
and chlordane have been investigated by the University of Basel, while the selected 
pesticides have been studied by the Federal Maritime and Hydrographic Agency (BSH). 
In connection with this project, polybrominated diphenylethers (PBDE) have been 
analysed by the Federal Environmental Agency, but the results are not available yet and 
will be published separately. 
The analytical methods for the determination and quantification of these substances had 
to be developed or improved during the project. For polychlorinated paraffins and 
chlordane, this included low resolution mass spectrometry combined with negative ion 
chemical ionisation (NICI-LRMS), electron ionisation tandem mass spectrometry (EI- 
MS/MS) and electron capture negative ion detection (ECNI-LRMS). It was the aim of 
the project to lower the limit of detection and to develop a methodology for use in 
routine monitoring for the identification of polychlorinated paraffins in sediment and 
biota. Methodologies for the quantification of the selected pesticides had to be 
developed for identification in water, sediment and biota. These methods had to have 
much lower limits of detection than the methods published so far. A further goal of the 
project is the development of recommendations for the OSPAR monitoring programme. 
Sampling was carried out jointly for all substances during routine monitoring cruises in 
the North Sea and Baltic Sea by the BSH for water and sediment samples and by the
