Extraction of 137Cs from Cetraria islandica lichen using acid solutions [PDF]
Journal of the Serbian Chemical Society, 2007 The extraction of 137Cs sorbed in samples of C. islandica using acid solutions was investigated. An equation describing the reduction of the 137Cs content in a dry lichen sample with the number of volumes of acid solutions used for successive extractions

Land Degradation &Development, EarlyView.ABSTRACT Soil erosion is a major environmental challenge in karst regions of Southwest China, where thin soils and high bedrock exposure accelerate land degradation. This study modified the RUSLE model by incorporating bedrock exposure rate to improve erosion simulation in Guizhou Province from 2000 to 2024.

Bed‐level tools for monitoring erosion and accretion patterns: Flume validation and field testing
Limnology and Oceanography: Methods, EarlyView.Abstract Monitoring short‐term changes in surface sediment elevation is fundamental to understanding erosion, transport, and deposition dynamics in shallow coastal environments. However, commonly used field approaches, such as horizontal markers, sediment erosion tables, subsurface sediment plates, or erosion pins, are not always cross‐validated under ...

Boreas, EarlyView.To assess how the eastern part of the Limfjord system has changed over the Holocene, relative to the wider Limfjord and western Baltic region, a sedimentary succession spanning c. 9600–150 cal. a BP was collected from Nibe Bredning, near Sebbersund, from a shallow coastal inlet along the eastern connection between the Limfjord and the Kattegat (north ...

Boreas, EarlyView.The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

Microplastic Dynamics in Sediment Layers of Two Ramsar‐Designated Wetlands
Water and Environment Journal, EarlyView.ABSTRACT Little is known about the vertical and spatial dynamics of microplastics in relation to hydrology and land use, particularly in African context. This study aimed to assess the abundance, type, colour and vertical distribution of microplastics in sediment from two Ramsar‐designated wetlands, the Makuleke and Nylsvley. Sediment core samples were

Reconnaissance study of watershed and cave sediment sources discharging from a karst spring, Iowa
Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.Abstract Springs discharging from karst landscapes provide sustainable flows to natural ecosystems and support productive fish hatcheries but sediment discharging from springs threatens the long‐term sustainability of hatcheries. In this study, we conducted a reconnaissance study to evaluate watershed and cave sediment sources discharging to Siewers ...

GEOCHEMICAL JOURNAL, 1977 A non-destructive gamma-ray spectrometry was applied to a number of volcanic products from Japan. Considerable amounts of 137Cs (∼10-13Ci/g) were determined in some volcanic rocks. The presence of 137Cs does not appear to have any relation to the type, age and spatial distribution of the volcanic rocks.

The FASEB Journal, Volume 40, Issue 16, 31 August 2026.The study aimed to test the role of three Src‐family kinases, Hck, Fgr, and Lyn in immune complex glomerulonephritis. Hck, Fgr, and Lyn were overexpressed in human lupus nephritis and mouse nephrotoxic nephritis. Combined genetic deficiency of the three kinases practically completely protected mice from nephrotoxic nephritis.
