Abstract

In
the present study, 23 human breast milk samples were collected in January 2009
from Fakous city, Al-Sharkia Governorate, Egypt. The samples were analysed
for organochlorine pesticides such as dichlorodiphenyltrichloroethane (DDT) and
its metabolites, α, β, and γ-hexachlorocyclohexane (HCH) isomers. The average
concentrations of HCHs and DDTs were 225 and 1315 ng/g lipid respectively. There
was no significant difference between the levels of OCP and  mother age, while there was a significant difference
and correlation between the levels of OCP and the number of times the mother
had breast fed (primiparous and multiparous) (p < 0.05). The results
suggested that DDT is still entering the environment depending on the observed ratio
of DDE/DDT. The levels of OCP in human milk recommended that we need to do more
regular pollutant monitoring programs.
