Determination and source apportionment of selected heavy metals in aerosol samples collected from Sebele
Likuku, Alfred Sello; Gaboutloeloe, Gilbert Kabelo; Mmolawa, Khumoetsile B. (Science Publication, 2013-05-17)Bush fires and dust in the dry winter months establish moderately high background levels of aerosols. Emissions into the atmosphere by copper mines, coal mines and vehicular emissions are all possible sources of air pollution ... -
The Influence of topography and vegetation canopy on the deposition of atmospheric particulates Studied with 210Pb and 137Cs soil inventory measurements
Likuku, Alfred Sello (University of Edinburgh, 2003)Naturally occurring radioactive isotopes of 210Pb and 7Be in the atmosphere, plant material and soil have been used to investigate the transport and removal of atmospheric aerosols from the atmosphere by precipitation and ...
