6.1 Aim of the Project 
The aim of the project „Identification of Organic Pollutants in the North and Baltic 
Seas“ is to identify and quantify toxic organic substances in the marine environment of 
the North and Baltic Seas for which environmental data are insufficient or not available 
at all. The selection of compounds is based on the lists of substances identified for 
priority action under the OSPAR and HELCOM Conventions and the European 
Commission’s Water Framework Directive. While implementing the European Water 
Framework Directive (EU WFD 2455/2001EU), it had been realised that no information 
was available on the occurrence of some of the compounds of the 33 priority pollutants 
listed in Annex X of the EU WFD. In particular, information on environmental 
concentrations in the coastal and marine waters was lacking. The sub-project carried out 
by Bundesamt fur Seeschifffahrt und Hydrographie (BSH) was aimed at monitoring the 
concentrations of the following four compounds of the WFD list: 
• Chlorpyrifos (-ethyl and -methyl) 
• Endosulfan (I and II) 
• Pentachlorophenol 
• Trifluralin 
In addition, 
• Dicofol and 
• Trichlorpyridinol 
were added to the list of compounds to be surveyed at the beginning of the project; both 
are not listed by the WFD. Trichlorpyridinol is a potentially stable degradation product
