Estimating typical sediment concentration probability density functions for European rivers [PDF]

open access: yes, 2005
Sediment in rivers is linked with qualitative and quantitative water problems throughout Europe. Sediment supply and transfer are part of a natural process of minimising gradients in the landscape.

Rapid Assessment of Intertidal Wetland Sediments [PDF]

open access: yes, 2012
Urbanization of coastal areas poses a severe threat to ecologically valuable intertidal wetlands. This paper presents a pragmatic approach called Rapid Assessment for Intertidal Wetland Sediments (RAITWS) for evaluating the sediment quality of intertidal

Seasonal Variation of Acid Volatile Sulfide and Simultaneously Extracted Metals in Sediment Cores from the Pearl River Estuary [PDF]

open access: yes, 2014
The simultaneously extracted metals/acid volatile sulfide (SEM/AVS) method is widely used to estimate the toxicity of metals in sediment. In this study, SEM and AVS concentrations were obtained by the cold-acid purge-and-trap technique during spring ...

Influence of salinity and water content on soil microorganisms

open access: yesInternational Soil and Water Conservation Research, 2015
Salinization is one of the most serious land degradation problems facing world. Salinity results in poor plant growth and low soil microbial activity due to osmotic stress and toxic ions.

Supercarriers of antibiotic resistome in a world’s large river

open access: yesMicrobiome, 2022
Background Antibiotic resistome has been found to strongly interact with the core microbiota in the human gut, yet little is known about how antibiotic resistance genes (ARGs) correlate with certain microbes in large rivers that are regarded as ...

Controls on Cyclic Formation of Quaternary Early Diagenetic Dolomite

open access: yesGeophysical Research Letters, 2018
The origin of sedimentary dolomite and the factors that control its formation within the geological record remain speculative. In most models, dolomite formation is linked to evaporative conditions, high water temperature, increasing Mg/Ca ratio ...
