dc.description.abstract | Eight trace elements, Si, Cl, K, Ca, Ti, Mn, Fe and Zn in the near-ground atmospheric aerosols were evaluated in the northwestern part of Mount Kenya using a dichotomous sampler and an EDXRF spectrometer. The samples were taken at 2 sites situated in Nanyuki area, which is roughly on the Equator. The sampler segregated the aerosol into two aerodynamic diameter (ad) size fractions, fine (<3.5 μm ad) and coarse (>3.5 and <18 μm ad). The elemental concentrations in the two size fractions were quantified and the elements assigned to known sources. Local wind blown dust related to agricultural activities and fire burning was found to dominate the lower tropospheric aerosols. There was inconclusive evidence of long range-transported aerosols being moved by night transport from the middle to the lower parts of the troposphere. Influence of the Indian Ocean marine aerosol was suggested but conclusive evidence was lacking. | en |
