TL;DR: In this article, the authors reported that new particle formation and growth rates were among the highest reported in the literature for continental boundary layer locations; median 10 nm formation rate was 2.2 cm−3 s−1 and median 10-30 nm growth rate 8.9 nm h−1.
Journal ArticleDOI

TL;DR: In this article, the authors analyzed one year (July 2006-July 2007) of measurement data from a relatively clean background site located in dry savannah in South Africa, and the annual median total particle number concentration in the size range 10-840 nm was 2340 cm −3.
Journal ArticleDOI

TL;DR: In this article, the authors used a recent dataset of 18 months of aerosol size distribution observations to understand the annual cycle of cloud condensation nuclei (CCN) in the South African savannah region.
Journal ArticleDOI
Assessment of natural radionuclide distribution in shore sediment samples collected from the North Dune beach, Henties Bay, Namibia
TL;DR: In this paper, the gamma spectrometry (HPGe) detector was used to determine gamma activity concentrations of 238 U, 232 Th and 40 K and their radiological hazards were presented.
Journal ArticleDOI
Assessment of metals pollution in sediments and tailings of Klein Aub and Oamites mine sites, Namibia
TL;DR: In this paper, the concentrations of investigated metals (Cr, Cu, Mn, Ni, Pb, Sr, V, Zn, Zr, Rb, Ba, Ca, Fe, K, S and Ti) and assess the pollution and contamination of sediments and tailings from Klein Aub and Oamites mine sites.
