“…Mean heavy metal contents in the Nakivubo Channelized stream sediments ranged from 64.05 ± 6.16 to 147.40 ± 17.98 mg/kg Pb; 0.88 ± 0.14 to 1.62 ± 0.24 mg/kg Cd; 63.75 ± 10.02 to 27.15±2.68 mg/kg Cu; 177.89 ± 16.37 to 442.40 ± 57.62 mg/kg Zn; 363.47 ± 18.34 mg/ Kothai et al, 2009;Chakravarty and Patgiri, 2009;Seshan et al, 2010). Other widely used reference metal elements include Al (Mn) (Nyangababo, 2005a;Kamaruzzaman et al, 2008;Ong and Kamaruzzaman, 2009).…”

“…Heavy metals may enter into aquatic ecosystems from anthropogenic sources, such as industrial wastewater discharges, sewage wastewater, fossil fuel combustion and atmospheric deposition (Linnik and Zubenko, 2000;Campbell, 2001;Lwanga et al, 2003;El Diwani and El Rafie, 2008;Idrees, 2009). Trace elemental concentrations in stream sediment compartments can be used to reveal the history and intensity of local and regional pollution (Nyangababo et al, 2005a). Sentongo (1998); Matagi (1998) and Kansiime et al, (1995) observed significant pollution load by organic and inorganic substances into the Nakivubo ecosystem.…”

“…The metals enter the river water and with the limited speed of water most metals are precipitated into the sediments. However, the study that was carried earlier to study the levels carried by air precipitation showed that very little of the trace metals are carried through by the precipitating air (Nyangababo, et al, 2005).…”

The aim of this work was to study the trace metals transfer between soil aquifers and the immediate sediments of the selected wetlands of Lake Victoria. The study covered five trace metals Pb, Cd, Cu, Zn and Mn as these are associated with vehicular traffic and with the combustion of fossil fuels which could both be significant sources of pollution within the wetlands of Lake Victoria basin. Three types of trace metal analyses from various locations of Katonga, Simiyu and Nyando catchments of Lake Victoria were performed: total concentrations, the concentrations in the non-residual fraction and the concentration in the exchangeable fraction. The soil characteristics: texture, pH and organic matter contents, were studied in relation to Cation Exchange Capacity (CEC) to assess the rate of movement of the metals between the soil and the wetland sediments. Eventually, the potential retention and leaching capacity of trace metals within the catchment soils and its possible impact on the composition of the receiving sediments of the wetlands were studied. The comparison between Nyando and Simiyu wetlands showed high variations in the soil characteristics and hence in leaching capacity of the studied metals. In general most areas in Nyando wetland required some measures to improve the CEC of the soil for higher agricultural productivity.

“…Human activities such as mining, landfill leachates, industrial emissions, vehicular emissions, fossil fuels, fertilizer erosion from agricultural run-off, herbicides and pesticides, sewage and municipal wastes all contribute to the accumulation of pollutants in nearby aquatic systems [1] [2], which are thought to be a safe site for disposal of polluted sediments [3]. Among the worst environmental contaminants are the heavy metals which are elements with atomic number > 20, specific density > 5 gm/cm 3 human metabolic activity when taken in through the food chain [6].…”

Freshwaters are not only used locally in many developing countries but they are often over exploited for domestic purposes, agriculture and disposal of industrial wastes which result in an overload of excess nutrients, harmful chemicals and heavy metals. Plant species together with sediments and water samples collected from eleven aquatic water bodies in the vicinity of industrial units in Kolkata were studied for their potential to uptake Pb, Cd and Cr under field conditions. Cd and Cr concentrations in the sediments were higher than background values considered to be toxic.Alternanthera philoxeroides and Eichhornia crassipes were the two invasive species present, with the former being more widely distributed. Among native plants, Ipomoea aquatica was the most abundant. Metal uptake in the plants differed among species, tissues and sites. Pb and Cd accumulation in root tissues for all plants in most sites suggested an exclusion strategy for metal tolerance. Since I. aquatica is widely consumed in many parts of SE Asia, its metal content should be checked before use since it was found to efficiently translocate both Pb and Cd from roots to shoots.The potential of A. philoxeroides as a metal excluder needs to be explored further since it translocates less to its shoots as compared to E. crassipes and I. aquatica.
