Residues of DDT in cod from Norwegian fjords

Samples of cod from 4 fjords located at the south western coast of Norway have been analysed for dichloro diphenyl trichloroethane residues. At locality A there are large fruit orchards and a small forest nursery. At C there are fruit orchards, while at B there is a forest nursery only. The fourth l...

Description
Summary:Samples of cod from 4 fjords located at the south western coast of Norway have been analysed for dichloro diphenyl trichloroethane residues. At locality A there are large fruit orchards and a small forest nursery. At C there are fruit orchards, while at B there is a forest nursery only. The fourth locality, D, had no known source of contamination. At A samples were collected at intervals during the spring of 1970. The dichloro diphenyl trichloroethane content in cod liver in samples from A and C was high. The mean values of 10-15 specimens ranged between 12 and 40 parts per million, calculated on the basis of extractable lipids. 3 specimens of cod showed residue levels of 90-135 parts per million dichloro diphenyl trichloroethane in liver tissue. Dichloro diphenyl trichloroethane values in cod from the two other localities were
