A total of 41 samples of maternal blood, milk, subcutaneous fat and umbilical cord blood were collected from mothers giving birth by Caesarean operation at Kenyatta National Hospital in Nairobi in 1986. The samples were analyzed for organochlorine contaminants. The main contaminants found in all the samples were p,p'-DDT (100%), p,p'-DDE (100%), o,p'-DDT(More)
Organochlorine compounds (OCPs) are toxic products capable of producing serious adverse health consequences. When used to control pests, certain OCPs persist in the environment and accumulate in the fatty tissues of living organisms, reaching higher levels in animals higher in the food chain. Many countries have therefore either restricted or banned the(More)
Residue levels of the chlorinated hydrocarbons p,p'-DDT (2,2-bis(p-chlorophenyl)-1,1,1-trichloroethane), p,p'-DDE (2,2-bis(p-chlorophenyl)-1,1-dichloroethane), hexachlorobenzene (HCB), alpha-, beta-, and gamma-hexachlorocyclohexane (HCH), aldrin, dieldrin, and polychlorinated biphenyls (PCBs) were determined in human milk of Kenyan mothers living in(More)
A total of 143 samples of Ugandan mothers' breast milk were analysed by gas chromatography for the presence and levels of DDT residues. The relationship between the level of DDT in the milk and the mother's age, parity, dietary habits, and place of usual residence were studied. DDT levels in the milk were not significantly related to the mother's age.(More)
