Abstract:

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,pí-DDT, p,pí-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,pí- DDE recorded 100% incidence ratio. Also p,pí-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.
