The use of portable X-ray spectrometer in monitoring anthropogenic toxic metals pollution in soils and sediments of urban environment of Dar es Salaam Tanzania

摘要

The levels of toxic metals in sediments and soils along high traffic Sam Nujoma highway and in the densely populated Sinza area in Dar es Salaam Tanzania were determined using portable X-ray fluorescence spectrometer (pXRF) and atomic absorption spectrometer (AAS) in order to assess the levels of the metals in the sediments and soil and evaluate the use of pXRF in monitoring anthropogenic toxic metal pollution in the urban environment.
