Determination of chlorinated pesticides

A preliminary intercomparison of levels chlorinated pesticides has shown that results of different laboratories disagree widely. Hence the need for collaborative trials with the aim of preparing certified material. Matrices for which certification is desirable are milk powder, pork fat and animal feed. Two milk powder samples were certified: a spiked one and one with natural (low), endogenous levels. The spiked material will mainly allow the user to verify the quantitative recovery of endogenous pesticides.

Certification of pork fat was not performed in the form of spiked materials. Instead, selected pigs were fed with a pesticide enriched diet, before taking their fat for certification of endogenous pesticides.
