Review: mine tailings in an African tropical environment—mechanisms for the bioavailability of heavy metals in soils
Sign Up to like & getrecommendations! Published in 2019 at "Environmental Geochemistry and Health"
DOI: 10.1007/s10653-019-00326-2
Abstract: Heavy metals are of environmental significance due to their effect on human health and the ecosystem. One of the major exposure pathways of Heavy metals for humans is through food crops. It is postulated in… read more here.

DOI: 10.1007/s10661-020-8160-2
Abstract: The distribution of pesticides in soils with consequences for their mobility, bioavailability and water contamination is mainly ruled by sorption processes. Such processes are seldom investigated in tropical soils. Thus, specific interactions between tropical soils… read more here.

DOI: 10.1007/s10705-020-10094-6
Abstract: Intensification of agriculture in the tropics is likely to increase reactive nitrogen (N) losses in the form of nitrous oxide (N2O), however, drivers of emissions from tropical soils remain poorly understood. This study investigated the… read more here.

DOI: 10.1016/j.chemosphere.2016.09.109
Abstract: This article discusses the adsorption of four organophosphorus pesticides-diazinon, dimethoate, methyl parathion, and sulfotep-in soil samples from four sites-Komchén, Xcanatún, Chablekal and Mocochá- in the northwest of Yucatan, Mexico. These pesticides have been detected in… read more here.
