AB  - Information on historical deposition of persistent organic pollutants (POPs) for 
      African lakes is very limited. We investigated historical deposition trends and 
      sources of POPs in sediment cores from Lakes Victoria (SC1), Bujuku (Buju2) and 
      Mahoma (Maho2). The latter two lakes are situated in the Rwenzori mountain range 
      in western Uganda. SC1 was taken from a central depositional area within the 
      Ugandan part of the lake. Profiles in Buju2 and Maho2 were used as a reference 
      for historical atmospheric deposition. For the post-1940 sediment deposits in 
      SC1, average focusing factor-adjusted fluxes (FFFs) of SigmaDDTs, polychlorinated 
      biphenyls (SigmaPCBs), hexachlorocyclohexanes (SigmaHCHs) and chlordanes (SigmaCHLs) were 
      390, 230, 210 and 120 ng m(-2) yr(-1). Higher fluxes of SigmaDDTs, SigmaPCBs, and SigmaCHLs 
      were observed in Buju2 and Maho2. The average FFF of HCB in Buju2 was the highest 
      while the values for Maho2 and SC1 were similar. The endosulfan FFFs in SC1 were 
      lower than in the alpine lake cores. Generally, Buju2 was a better reference for 
      historical atmospheric deposition of POPs than Maho2 probably due to distortion 
      of the latter's profile by Lake Mahoma's forested catchment. Profiles of 
      p,p'-DDE, SigmaCHLs and HCB in SC1 were consistent with atmospheric deposition while 
      profiles of PCBs and HCHs were indicative of particle-bound loadings from 
      additional sources. Profiles of endosulfans, DDTs, and chlordanes were consistent 
      with influence of other factors such as anoxia, and dilution. Further studies of 
      spatial resolution of historical deposition, especially in near-shore deposition 
      areas of the lake are recommended.
