      Victoria.

AB  - Organochlorine (OC) residues were analysed in 117 sediment samples collected from 
      four bays of the Uganda side of Lake Victoria. The sediments were collected with 
      a corer at a depth of 0-20 cm, and extracted for OC residues using a solid 
      dispersion method. The extracts were cleaned using gel permeation chromatography 
      and analysed for pesticide residues using a gas chromatograph (GC) equipped with 
      an electron capture detector. The results were confirmed using a GC equipped with 
      a mass spectrometer (MS). A total of 16 OC residues, most of them persistent 
      organic pollutants (POPs) were identified and quantified. The OC residue levels 
      were expressed on an oven dry weight (d.w.) basis. Endosulphan sulphate, in the 
      range of 0.82-5.62 mug kg(-)(1) d.w., was the most frequently detected residue. Aldrin 
      and dieldrin were in the ranges of 0.22-15.96 and 0.94-7.18 mug kg(-)(1) d.w., 
      respectively. DDT and its metabolites lay between 0.11-3.59 for p,p'-DDE, 
      0.38-4.02 for p,p'-DDD, 0.04-1.46 for p,p'-DDT, 0.07-2.72 for o,p'-DDE and 
      0.01-1.63 mug kg(-)(1) d.w. for o,p'-DDT. The levels of gamma-HCH varied from 0.05 to 5.48 
      mug kg(-)(1) d.w. Heptachlor was detected only once at a level of 0.81 mug kg(-)(1) d.w., 
      while its photo-oxidation product, heptachlor epoxide, ranged between 
      non-detectable (ND) to 3.19 mug kg(-)(1) d.w. Chlordane ranged from ND to 0.76 mug kg(-)(1) 
      d.w. Based on the threshold effect concentration (TEC) for fresh water 
      ecosystems, aldrin and dieldrin were the only OCs that seemed to be a threat to 
      the lake environment.
