Certification of organochlorine pesticides in fish oil

Exploitable results

General Information : Organochlorine pesticides are determined in a number of marine environmental matrices by laboratories of member states. A RM is urgently needed for these measurements in marine monitoring programmes of the Oslo and Paris commission and the North Sea task force. A fish oil containing indigenous levels of organochlorine pesticides which represents a medium level of contamination will therefore be prepared and stabilized with antioxidant. After ampouling, homogeneity and stability trials the group of expert laboratories will undertake a programme of certification. Achievements : The certification of the organochlorine pesticides in cod liver oil (CRM 598) has been preformed according to the recommendations provided in ISO GUIDE 35-1985, section 8 : certification by interlaboratory testing
