| Summary: | </i><b>Abstract: </b><p align=\"justify\"><i> An examination on pesticide residues in human mother milk obtained from Pangandaran, West Java has been carried out. The samples were extracted with acetonitrile. This extract was then purifield by reextraction with n-hexane and by chromatography through a florisil column.Subsequent analysis was done by electron capture-gas chromatography.<p align=\"justify\"> The gas chromatographic analysis showed the presence of pp\'DDT [1,1-bis-(p-chlorophenyl)-2,2,2- trichloroethane] and its metabolite pp\'DDE [2,2-bis-(p-chlorophenyl)-1,1 - dichloroethylene] in human mother milk. The average amounts of 0.173 ppm pp\'DDT and 0.320 ppm pp\'DDE were found in 21 samples of human mother milk determined.<p align=\"justify\"> The identification of pp\'DDT and pp\'DDE was confirmed by thin layer chromatography, using aluminium oxide G as the adsorbent, n-heptane as the solvent and silver nitrate solution as the chromogenic reagent followed by ultra violet irradiation.</p> |
