ICP-MS Measurement of Trace and Rare Earth Elements in Beach Placer-Deposit Soils of Odisha, East Coast of India, to Estimate Natural Enhancement of Elements in the Environment

Molecules, 2021
Inductively coupled plasma mass spectrometry (ICP-MS) has been used to measure the concentration of trace and rare earth elements (REEs) in soils. Geochemical certified reference materials such as JLk-1, JB-1, and JB-3 were used for the validation of the

Physicochemical Characteristics and Quantification of Heavy Metals in Compost of Municipal Organic Solid Waste in High Andean Areas of Peru

Applied and Environmental Soil Science, Volume 2026, Issue 1, 2026.
The study evaluated the quality of compost made from municipal organic solid waste at the CEPASC plant in Concepción, Junín (3414 m above sea level). Compost was analyzed at two maturation stages: 60 days (Compost A) and 120 days (Compost B), using international protocols (TMECC) and advanced techniques such as inductively coupled plasma mass ...

Sediments as Sentinels of Pollution Episodes in the Middle Estuary of the Tinto River (SW Spain)

Soil Systems, 2023
Estuaries are excellent environments for identifying pollution episodes that have affected river basins, as their sediments are the final destination of some of the pollutants. This paper studies the geochemical evolution of five elements (As, Co, Cu, Pb,

Assessing the Levels of Potentially Toxic Elements in Roadside Soil Dust Samples Collected From Southwest Florida: Implication for Human Health

Applied and Environmental Soil Science, Volume 2026, Issue 1, 2026.
Pollution of urban soils with metals is of great concern worldwide owing to their persistent and nonbiodegradable nature. The current study investigated the presence and levels of some selected potentially toxic elements in the roadside soil dust samples collected from Fort Myers and surrounding communities. The study further assessed the pollution and

Ecotoxicological Analysis of Fallow Soils at the Yamal Experimental Agricultural Station

Техника и технология пищевых производств, 2022
The agricultural use of soils is limited by their contamination with various compounds and low contents of nutrients. We aimed to study the unique soils of the Yamal Experimental Station to determine their contamination with heavy metals and assess their

Assessment of heavy metal contamination in sub-tropical riverine sediments using geoaccumulation index

Ecotoxicology and Environmental Contamination, 2017
Heavy metal determination in surface sediment allows pollutant assessment when the detection in the water column is not possible. Geoaccumulation Index (Igeo) and the Sediment Quality Guidelines (SQGs) were used to quantitatively evaluate the degree of heavy metal contamination in fluvial sediments.
