Distribution and Assessment of Heavy Metal Levels Using Geoaccumulation Index and Pollution Load Index in Lake Edku Sediments, Egypt [PDF]
International Journal of Environmental Monitoring and Analysis, 2017 The aim of this study is to determine and assessment of some heavy metals content (Fe, Mn, Zn, Cu, Ni, Cr, Co and Pb) in the sediment of Lake Edku. Surface sediment samples were collected in September (summer) 2016. The metals content in the Lake sediments decreased in the order of Fe > Mn >Cr >Co >Zn > Cu >Ni= Pb.

Journal of Chemistry, Volume 2025, Issue 1, 2025.This study examined the presence of seven prevalent potentially toxic elements (PTEs) in clays consumed by predominantly pregnant women. We utilized near‐infrared spectroscopy (NIRS) and multivariate analysis to examine the presence of PTEs in 40 clay samples collected from 8 primary marketplaces in Kumasi, Ghana.

Blowin’ in the Wind: Mapping the Dispersion of Metal(loid)s From Atacama Mining
GeoHealth, Volume 8, Issue 10, October 2024.Abstract The Atacama Desert’s naturally elevated metal(loid)s pose a unique challenge for assessing the environmental impact of mining, particularly for indigenous communities residing in these areas. This study investigates how copper mining influences the dispersion of these elements in the wind‐transportable fraction (<75 μm) of surface sediments ...

Soil contamination evaluation by Enrichment Factor (EF) and Geoaccumulation Index (Igeo) [PDF]
, 2015 Heavy metals are natural constituents of soils and their concentration varies depending on parental materials. The soils were formed by. In the last years, the content of heavy metal in soils has increased due to human activities as: distribution of fertilizers, pesticides, industries, waste disposal and air pollution.

Integrated Environmental Assessment and Management, Volume 20, Issue 1, Page 148-158, January 2024.Abstract The Fundão mine tailings dam rupture of 2015, in the Rio Doce basin, Brazil, resulted in the deposition of tailings downstream of the dam. It has yet to be determined if metals associated with the tailings have contributed toxicity to organisms, burying a time bomb that could be ticking.

The Content of Heavy Metal in the Labu Riverbed Sediments: An Assessment of the Level of Pollution Applying Sediment Quality Guidelines and Geoaccumulation Index [PDF]
American Journal of Environmental Sciences, 2016 River bed sediments from thirteen (13) sampling stations, from Labu River were collected in June and December 2014. The aim is to identify the source and ascertain the current levels of heavy metal pollutions. The selected heavy metals (Cr, Cu, Fe, Ni, Zn, As, Cd and Pb) were analysed by using Inductively Couple Plasma Mass Spectrophotometry (ICPMS ...

Resource conundrum in Mongolia: Soil contamination from coal and copper–molybdenum mining
Soil Use and Management, Volume 40, Issue 1, January 2024.Abstract Soil contamination and the resulting ecological disturbances are a common phenomenon in mining areas, including the vicinities of the largest and oldest open‐pit mining areas in Mongolia. In this work, the potential ecological risk index (RI), Nemerow integrated pollution index (PIN), and Geoaccumulation index (Igeo) were used to estimate the ...
