• Summary of Experiments and Influencing Factors of Sediment Settling Velocity in Still Water (2024) · Water · cited 18× · doi

  Theoretical approaches often overlook external factors such as temperature, salinity, organic matter, and pH. Laboratory experiments may not accurately represent natural sedimentation processes. Field observations can be disrupted by equipment and may not provide accurate measurements of sediment particle size.

• Potentially toxic element contamination in water and sediments of the Ergene river basin (Türkiye): ecological and human health risk assessment (2026) · International Journal of Environmental Science and Technology · doi

  Sediment-related physicochemical parameters such as grain size and organic matter/ TOC were not measured during the sampling campaign, which restricts the ability to fully interpret sediment contamination dynamics. The health risk assessment was limited to waterborne elements and exposure pathways, excluding potential risks associated with sediment ingestion or dermal contact.
