Update: Organochlorine Pesticides – New Analytical Approach Available by End of April 2018
A New Method for Fish Oil Ethyl Esters Developed
Conventional pesticide methods often show matrix interferences for ethyl ester samples, leading to impairments during data evaluation. Eurofins now developed an innovative method especially for fish oils of the ethyl ester type:
After enzymatic hydrolysis of the ethyl esters, a SPE clean-up removes the now free fatty acids. This approach allows the simultaneous analysis of persistant analytes as well as the set of pesticides which is more sensitive and normally lost by application of conventional treatments with acid during sample preparation. Quantification takes place by GC-MS/MS and isotope dilution for robust and reliable quantification.
The new product and test codes will be available at the end of April 2018. LOQs will be as low as possible and at least 0.01 mg/kg for most of the parameters of interest. The turnaround time will be 5 days.
With this new approach we are glad to support our clients to comply with changing market demands and to meet highest industry standards.

Interesting Facts on Organochlorine Pesticides
Organochlorine Pesticides (OCP) are used as wood preservatives or pesticides. The production and/or use of some of these compounds have been banned in Europe, USA and Canada since long. However, in numerous developing countries and Eastern Europe they are still produced and used.
Organochlorine Pesticides are persistent, liposoluble and bioaccumulate especially in the fat tissue. This bioaccumulation is their main risk potential due to the resulting chronic effects. Animal experiments e.g. definitely proved a carcinogenic effect of DDT. This correlation has neither been finally proven nor ruled out for humans.
Toxaphene, however, is very toxic for fishes, water organisms and algae. A carcinogenic impact and the effects on the fertility of humans are unclear.
Production and use of OCP is globally regulated in the Stockholm Convention on Persistent Organic Pollutants.
