Chlorinated Hydrocarbon Residues (PCB and DDT) in Human Liver, Adipose Tissue and Brain in Finland

In this work the concentration of chlorinated hydrocarbons (PCB and DDT) was analyzed from 73 autopsy samples. Half of the material came from the coastal area of the Gulf of Bothnia and the other half from Central Finland. The correlation of the concentration of the drug to age, sex and the locality was studied as well as the occupation of the dead subjects.

An evaluation of a model ecosystem with DDT

The reproducibility, variability, and reliability of a simple aquatic-terrtestrial model ecosystem experiment was tested with p,p'-DDT. The variation among the model replicates as well as within the units was studied by using hierarchal analysis of variance. the complete budget of the chemical was calculated and a theoretical transport model was constructed. The degradation and accumulation of DDT was followed by gas chromatographic residue analysis, which showed good reproducibility of the experimental design. The degradation of DDT in the model was similar to that found in the field, but the determination of concentration factors was questionable. The material balance tables revealed that…
