Introduction With urbanization and industrialization in the developing world, urban peri-urban agriculture is increasingly contributing to food systems, employment, income generation opportunities. However, may release harmful pollutants, including heavy metals trace elements into agricultural soils, posing ecological, environmental public health concerns. This paper assessed potential risks of soil contamination with farmlands Nairobi city catchment Kenya. Methods A total 60 samples were...
ABSTRACTABSTRACTThe mining and processing of copper in the Kilembe area, Western Uganda from 1956 to 1982 left behind several tailing sites containing cupriferous coralliferous pyrites. A study was conducted establish concentrations trace elements point sources (tailings) within mine distribution catchment soils. Mine tailings soils were sampled, acid digested tested for elemental using ICP-MS. Tailings appeared be main element contamination with very high (mg kg−1) Cu (240–11500), Co...
Past copper mining within Kilembe valley between 1956-1982 left behind mine tailings rich in potentially toxic elements (PTEs). This study was conducted to assess the concentrations of PTEs soils and potential uptake by forage. Tailings, forage were collected analyzed using ICP-MS. The established that over 60% grazed plots contained high Cu, Co, Ni As. Copper 35%, Co 48% 58% soil exceeded thresholds for agricultural soils. Bio-accumulation Zn observed. Zinc 14% guinea grass (Panicum...
