This study was conducted to determine the types and levels of Organochlorine pesticide residues in
the breast milk of 21 primiparae mothers in La, a suburb of Accra an urban community in the Greater Accra
region of Ghana. Liquid-liquid extraction procedure was employed and extract clean-up was done using silica
gel solid phase extraction. Fourteen (14) different organochlorine pesticides residues namely p,p’-DDT,
p,p’-DDE, gamma-HCH, delta-HCH, heptachlor, aldrin, Endrin, endrin-aldehyde, endrin-ketone,
alpha-endosulphan, endosulphan-sulphate, gamma-chlordane, dieldrin, and methoxychlor were identified and
quantified in the individual breast milk samples using a Gas Chromatograph (GC) with an Electron C apture
detector. The GC recoveries of spiked samples were between 89 to 97%. P,p’- DDE recorded 100% incidence
ratio. Also p,p’-DDT, delta-HCH, gamma-HCH, and endosulfan sulfate recorded incidence ratios of 76.79,
95.25, 80.95 and 85.71%, respectively for the breast milk samples. The concentrations of organochlorine
pesticide residues in the human breast milk samples ranged from 1.839 to 99.05 :μg/kg fats. With the exception
of Endosulphan Sulphate whose mean concentration (99.052 :μg/kg) was above the Australian Maximum
Residue Limit (MRL) of 20 :μg/kg for milk, the mean concentrations for all the other organochlorines detected
were below their respective limits. |
