“…In natural aquatic ecosystems, metals are normally at the levels varying from nanogram to microgram in a liter. Recently, heavy metals' exceeding the carrying capacity of waters has caused some problems with regards to aquatic ecosystem balance (Ndimele and Jimoh 2011). In aquatic system, where the input of pollutants is not continuous and they are thus get diluted, the analysis of plant tissues provides information about the quality of the system (Baldantoni et al 2005).…”

“…The soil samples were collected from soil surface (0 -20cm depth) at ten different spots with the help of stainless steel spoon and made into a composite sample. The soil samples were placed into a nitric acid treated polythene bag to prevent metals from adhering to the containers and then transported to the laboratory where they were air dried for about 3days then oven-dried to constant weight at 105 , disaggregated in a ceramic pestle and mortar, ground to powder and sieved, (Kisamo, 2003, Ndimele andJimoh, 2011).…”

The concentrations of heavy metals in agricultural soils at Pindiga, Ako LGA, Gombe, were determined using an atomic absorption spectrophotometer (AAS). The mean concentrations of heavy metals in soil samples are as follows, Fe (21.31 mg/Kg), Zn (0.20 mg/Kg), Cd(1.58 mg/Kg),Cr(2.3mg/Kg) and Pb (36.10 mg/Kg). The concentration of heavy metals in samples increased in the following order, Fe > Pb > Cr > Cd > Zn. The mean values for some physiochemical parameters of the water samples are; pH (5.7), moisture (36.1), the concentrations of heavy metals in water samples were less than the permissible limits for heavy metals in soils set by USEPA / WHO.

“…Uses: Water hyacinth is extensively grown in "waste water treatment and clean-up of polluted" environments [168,169], and also in bio energy production [170]. Water hyacinth is also used in paper-making industry, in making ropes, floor mats, in biogas production etc., in Indonesia and India [5,6].…”

Aquatic ecosystems in Botswana have been under threat by the aquatic alien invasive plant species viz., salvinia Salvinia molesta Mitchell, water lettuce Pistia stratiotes L., and water hyacinth Eichhornia crassipes (Mart.) Solms-Laub. While salvinia has been termed the major threat to the Botswana wetlands, water lettuce and water hyacinth are considered to be of minor importance. This review presents the species biology, distribution, historical spread, negative impacts, control achieved right from their discovery in the country by referring to their control and management in the world.Having infested the Kwando-Linyanti-Chobe Rivers in the 1970s, salvinia was initially tried by the use of herbicides, paraquat and glyphosate, between 1972 and 1976. With the discovery of the host specific biological control weevil Cyrtobagous salviniae Calder and Sands in 1981, the weevil was introduced by Namibians on Kwando and Chobe Rivers in 1983 and by Botswana in 1986 in the Okavango Delta. While the control was slowly establishing in Kwando-Linyanti-Chobe Rivers, it became apparent that lakes and perennial swamps within and outside Moremi Game Reserve of the Okavango Delta were infested with salvinia from 1992 onwards.With continuous and sustained liberation of the weevil in the Kwando-Linyanti-Chobe Rivers and in the Okavango Delta between 1999 and 2000, salvinia control was achieved by 2003, and since then the weevil constantly keeps the weed at low levels. The success is mainly due to sustainable monitoring through the application of physical and biological control methods. However, salvinia is still threatening the Okavango Delta due to factors such as tourism activities, boat navigation fishing and transporttion by wild animals.The first occurrence of water lettuce was recorded on Kwando and Chobe Rivers in 1986. Its biocontrol weevil Neohydronomous affinis Hustache was released in the year 1987. The weevil became extinct in Selinda Canal and Zibadianja Lake on Kwando River due to dry and wet events for over 10 years and the weed had been under control biologically on Chobe River. Having surface covered the Selinda and a part of the Zibadianja in high flood and rainfall in 1999/2000 season, research was undertaken to contain water lettuce, which led to its eradication by 2005. Regular physical removal of the water lettuce prior to fruit maturity is an effective method of control or eradicating the weed in seasonal water bodies.The Limpopo Basin (shared by Botswana, South Africa, Zimbabwe and Mozambique) has become vulnerable to water hyacinth infestation. Water hyacinth infested the trans-boundary Limpopo River in 2010 sourced from Hartbeesport Dam on Crocodile River in South Africa. Botswana and South Africa have been consulting each other to implement integrated control of the weed jointly in the Limpopo River. Water hyacinth could be a continuous threat to the dams and the rivers in the Limpopo basin if its control is not taken seriously.These three species are found growing in Botswana in a range of pH...
