Dissolved PCB's and chlorinated hydrocarbon insecticides in the baltic,determined by two different sampling procedures

From the Hanö Bight, south of Sweden, in the Baltic, seawater samples were taken for measuring the concentrations of dissolved PCB's and OCP's by two different methods. The results are not only in agreement with other data from this and comparable regions, they also show no differences in the two sampling techniques. As a consequence, the ship-bow intake pump is recommended as an instrument to process large water volumes.
