Processes controlling geogenic arsenic distribution in soils formed from iron-rich sedimentary rocks

open access: yesJournal of Hazardous Materials
Soils formed from Fe-rich sedimentary rocks can contain elevated As contents. Although the geogenic origin of As in these soils is recognized, the processes controlling its distribution within soil profiles and its mobility in topsoils are still unclear, limiting effective prediction of soils with potentially hazardous As contents for human health ...

Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 247-262., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Secondary enrichment of soil by alkaline emissions: the specific form of anthropogenic soil degradation near magnesite processing factories and possibilities of land management [PDF]

open access: yesLand Degradation & Development, 2020
Over the past 90 years, anthropogenic degradation of soil caused by alkaline, magnesium-rich dust deposit has presented a serious problem near magnesite processing factories in Jelšava and in Lubeník (Slovakia). The objective of this study was to investigate the chemical and biological soil properties in 14 sampling sites at different distances from ...

Evaluation of tectonically enhanced radon in fault zones by quantification of the radon activity index

open access: yesScientific Reports, 2022
This work highlights the importance of the Geogenic Radon Potential (GRP) component originated by degassing processes in fault zones. This Tectonically Enhanced Radon (TER) can increase radon concentration in soil gas and the inflow of radon in the ...

Lanthanides Release and Partitioning in Municipal Wastewater Effluents

open access: yesToxics, 2022
The use of lanthanides is increasing in our society, whether in communication technologies, transportation, electronics or medical imaging. Some lanthanides enter urban wastewater and flow through municipal wastewater treatment plants (WWTPs).
