Organochlorine Pesticides (OCP) – New Analytical Approach on Schedule
A New Method with Low LOQs for Fish Oil Ethyl Esters in Final Development
Editor’s note: The new analytical approach for fish oil ethyl esters has now been developed. Please note our update “Organochlorine Pesticides – New Analytical Approach Available by End of April 2018”
Conventional pesticide methods often show matrix interferences for ethyl ester samples, leading to increased LOQs. Eurofins GfA Lab Service now has developed an innovative method especially for these products: After enzymatic cleavage, the interfering substances are removed and lower LOQs can be achieved. The full method validation will be complete in January 2018. LOQ will be as low as possible and at least 0.01 mg/kg for most of the analyses of interest.
With this new approach we are glad to support our clients to comply with changing market demands and to meet highest industry standards.

Background Information 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 proved nor excluded 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.
