Abstract
Samples of cod livers from 21 different locations in Norwegian fjords were analysed by gas liquid chromatography for chlorinated insecticides and PCBs. All samples contained DDT, DDE, DDD and PCBs. Mean DDT residue levels ranged between 0,2 ppm and 25 ppm and PCB values between 0,3 ppm and 3,9 ppm, calculated on a wet weight basis. The highest concentrations of DDT were found in cod from areas with fruit orchards. The present use of DDT in forest nurseries does not contaminate the neighbouring fjords to a noticeable degree.
