(Groundwater for Sustainable Development, 2021)Hydrochemistry of crater lakes (n = 15) in the Ndali-Kasenda cluster was deciphered using standard methods of the American Public Health Association to understand the major ion chemistry; spatial distribution, occurrence, ... -
Heavy Metal Bioaccumulation by Maize Grown on a Ferralsol Amended with Urban-Based Biosolid Wastes
(Journal of Agricultural Chemistry and Environment, 2021)Organic waste materials as soil amendments are one of the topical approaches applauded for achieving sustainable agriculture world-over. The objective of this study was to investigate the effect of urban-based biosolid ... -
Abell 1430: A merging cluster with exceptional diffuse radio emission
(Astronomy and Astrophysics, 2021)Context. Di_use radio emission has been found in many galaxy clusters, predominantly in massive systems which are in the state of merging. The radio emission can usually be classified as relic or halo emission, which are ... -
Heavy Metal Accumulation in Vegetables Grown in Rock Soils of Kilembe Copper Mine, Kasese, Western Uganda
(Asian Journal of Applied Chemistry Research, 2022)Aim: Active mining in Kilembe copper mine, Kasese district, Uganda ended about four decades ago. However, various health problems are believed to be from the effect of mining activities that took place in the area. In this ... -
Dichlorodiphenyltrichloroethane (DDT) and its metabolites in house dust, soil and selected food crops from indoor residual sprayed areas of Apac and Oyam Districts, Uganda
(African Journal of Pure and Applied Chemistry, 2022)Dichlorodiphenyltrichloroethane (DDT) levels and its metabolites are reported in 75 soil and 75 vegetable samples from the vicinity of homesteads sprayed with DDT during indoor residual spraying (IRS) pilot exercise, ... -
