Swampy agricultural soils could be contaminated as a result of accumulation of heavy metals through emission from industrial areas, mines tailings, metal wastes, gasoline, paints, fertilizers, manure, sewage sludge, pesticide, waste water irrigation, coal combustion residue, spil...
Heavy metals are metalloids of environmental concern, especially in urban and peri-urban small scale farming systems. Plants are contaminated with heavy metals through different pathways, including uptake from soil and from the atmosphere. These pathways need to be distinguished...
This study investigates the physico-chemical parameters of water and quantification of heavy metals (zinc, copper, lead, chromium and cadmium) in the gill, liver and flesh of Oreochromis niloticus, Hemichromis fasciatus, Sarotherodon galilaeus and Oreochromis aureus in River Ofin...
