[Burden of DDT, HCH, HCB and PCB in human milk in the former German Democratic Republic. Research and toxicologic evaluation]. / Belastung der Humanmilch in der ehemaligen DDR mit DDT, HCH, HCB, PCB. Untersuchung und toxikologische Bewertung.

The decreasing tendency of the contamination of human milk with residues of organochlorine compounds (DDT, HCH, HCB, PCB) has been confirmed by our investigations also for the territory of the former GDR. Compared with the residue-situation existing in the FRG, the contamination of breast milk with DDT-metabolites 4,4'-DDE and 4,4'-DDT were elevated. A positive correlation was found between age and HCB-exposure, urban residency and 4,4'-DDE, beta-HCH and PCB, and smoking and beta-HCH-residues in human milk.
