“…1,1,1-Trichloro-2,2-bis(p-chlorophenyl)ethane dichlorodiphenyl-trichloroethane (DDT) is one of the "dirty dozen" persistent organic pollutants (UNEP, 2008) whose manufacture and use was banned in many countries worldwide in the 1970's (Tsuda, 2012) except in cases of public health emergency (ASTDR, 2002). In Uganda, the use of DDT was prohibited in the mid 1980's (Kasozi et al, 2006), however; it was used in the recent past for controlling malaria in the districts of Oyam and Apac in Northern Region.…”

Silver fish (Rastreneobola argentea) samples from Lake Victoria and Lake Kyoga were analyzed for dichloro-diphenyl-trichloroethane (DDT) and metabolites using a Gas Chromatograph equipped with an Electron Capture Detector. Confirmation of results was by Gas Chromatography equipped with Mass Spectrophotometer (GC-MS). DDT and metabolites were detected in 90% of the total samples (63 out of 70). pp' DDT was the most frequently detected residues in the samples whereas op' DDE was detected in none of the samples. The mean ΣDDT concentrations in fish from Lake Victoria varied from 0.147 to 0.396 µg/kg while that in Lake Kyoga varied from 0.207 to 0.506 µg/kg dry wt of fish sample. The concentration of total DDT in the fish samples ranged from 0.147 to 0.506 µg/kg dry wt. This was far below the recommended FAO limit of 5000 µg/kg for fish (edible portion), implying that the fish are safe for human consumption.
