Influencing Factors of Phosphorus Mobility and Retention in the Sediment of Three Typical Plateau Lakes

open access: yesToxics
The mechanisms driving changes in the stability of phosphorus (P) in sediments under lake ecosystem degradation remain poorly understood. This study investigated the P-binding forms in sediments from three plateau lakes with different trophic states in ...

RETRACTED: Assessing Mercury Contamination Levels in the Sediments of Two Pyrenean Lakes

open access: yesDiversity
Mercury, a trace metal, is a persistent environmental pollutant that can be detected even in remote regions, including high-mountain lakes. This study examined mercury concentrations in the sediment of two lakes in the French Pyrenees, the Legunabens and

Sedimentation of microplastics interacting with sediment

open access: yes
The widespread presence of microplastics (MPs) in freshwater environments underscores the need to better understand their temporal and spatial dynamics. Investigating the settling velocity (W) of MPs in the water column is crucial for comprehending their transport mechanisms within river systems.

Ecological risk assessment of heavy metal contamination in Xiaohai Lagoon, Hainan island, China

open access: yesFrontiers in Marine Science
Xiaohai Lagoon has faced significant natural and anthropogenic pressures, necessitating a heavy metal contamination assessment. Sediment and water samples were collected in 2024 during dry and wet seasons to assess heavy metal pollution and ecological ...

Microbiology of sediments in lakes of differing degrees of eutrophication [PDF]

open access: yes, 1980
A general survey was carried out on the sediments of seventeen lakes, ranging from oligotrophic to eutrophic, in the English Lake District. Several variables not directly concerned with the population of bacteria were measured to provide background ...

An experimental test of endfire synthetic aperture sonar for sediment characterisation

open access: yesIET Radar, Sonar & Navigation
The validation of seafloor scattering models used for seabed characterisation requires quantifying the contributions from the sediment interface and volume to the total acoustic returns.
