Fourteenth International Conference on Climate Change: Impacts & Responses

Abstract

Heavy metal pollution of agricultural soils has progressively evolved into a major environmental issue in Africa and around the world. Heavy metals following pre-treatments were analyzed using an inductively coupled plasma-mass spectrometry (ICP-MS) system in this study. Using data from 54 topsoil samples collected from hydrodynamic farmlands in 18 different African countries, the concentrations, spatial distributions, and relationships between soil features and heavy metals contaminants were examined, as well as their human and ecological dangers. The results show that, the average concentrations of the eight heavy metals on soil environmental quality and soil pollution risk control standards for agricultural land in China. There is a correlation between soil pH, organic matter, and heavy metals. The spatial distribution differences among the seven regions were impacted by geological and human activities. Environmental exposure is the tool used in assessing the risks of heavy metals to human health. Noncarcinogenic risks for both adults and children surpass the safety limit.
