[Residues of organochlorine insecticides and PCBs in some Norweigian foods (author's transl)].

Oats, barley, wheat and rye, meat from sheep, pork, beef and chicken/broiler, boullion, margarine and cod roe were analysed by gas liquid chromatography for chlorimated insecticides and PCBs. Residues of PCBs, lindane, DDT and metabolites were found in only a few of the samples. Traces of dieldrin were observed in grain. Lidan was found in grain with the highest single value of 0.013 ppm and with the mean value of 0.008 ppm. DDT residues were found in 37 percent of all samples and the highest concentration were in chicken/broiler with mean value of 0.02 ppm. The values are calculated on wet weight basis.
