Assessment of heavy metal enrichment and degree of contamination around the copper-nickel mine in the Selebi Phikwe Region, Eastern Botswana
Likuku, Alfred Sello; Mmolawa, Khumoetsile B.; Gaboutloeloe, Gilbert Kabelo (Horizon Research Publishing Cooperation, 2013)This paper focuses on heavy metal (Co, Cu, Fe, Pb, Mn, Ni and Zn) enrichment and degree of contamination in the soils windward of the Selebi Phikwe copper and nickel mine (eastern Botswana). Pollution by these metals was ... -
Factors influencing ambient concentrations of 210Pb and 7Be over the city of Edinburgh (55.9°N, 03.2°W)
Likuku, Alfred Sello (Elsevier, 2006)Concentrations of 210Pb and 7Be in air were continuously monitored, using a high-volume air sampler and a high-resolution gamma-ray spectrometer, during the period of July 2002 to June 2003 at the University of Edinburgh ... -
Health risk assessment of heavy metals via dietary intake of vegetables irrigated with treated wastewater around Gaborone, Botswana
Likuku, Alfred Sello; Obuseng, Gloria (International Conference on Plant, Marine and Environmental Sciences, 2015-01)Heavy metal concentrations of Cd, Cr, Cu, Ni, Pb and Zn in green peppers (Capsicum annuum) and tomatoes (Solanum lycopersicum) irrigated with treated wastewater from the Glen Valley farms were determined. Concentrations ... -
Inventories of fallout 210Pb and 137Cs radionuclides in moorland and woodland soils around Edinburgh urban area (UK)
Likuku, Alfred Sello (Elsevier, 2006)Inventories of fallout 210Pb and 137Cs have been measured in moorland and woodland soils around the Edinburgh urban area, using a high purity germanium detector. The 210Pb inventories in moorland soils were relatively ... -
Preliminary investigation of transfer of metals from soil to vegetables: Case study of Spinacia oleracea L.
Mokgolele, Mosiamisi; Likuku, Alfred Sello (Academic Journals, 2016-09)The objective of the study was to measure concentrations of Cu, Ni and Zn in Spinacia oleracea cultivated at a site near the copper and nickel mine in Selebi Phikwe. The mean concentrations (in dry matter-basis) of Cu, Zn ... -
Wet deposition of 210Pb aerosols over two areas of contrasting topography
Likuku, Alfred Sello (Institute Of Physics Publishing Ltd, 2006-11-24)Deposition fluxes of 210Pb on low and moderately high-elevation sites of Edinburgh (Scotland) and mid-Wales, respectively, have been measured. The excess 210Pb fluxes in moorland Edinburgh soils did not vary significantly ...
