Summary: This study conducted field work and collected data in a wave- and current-driven estuarine environment to examine cohesive sediment flocculation dynamics. The study found that the factors driving floc size variability differed between locally sourced sediment and suspended sediment advected from upstream. The analysis also revealed seasonal variability in these trends and presented evidence of a relationship between floc size and the inverse turbulent Schmidt number.

Summary: Bromide ions act as a catalyst to enhance the oxidation kinetics of thallium by chlorine in water treatment. The different species of thallium and bromine are kinetically relevant to the enhanced oxidation process. The knowledge of species-specific reactivity of thallium with bromine species can help predict thallium mobility in chlorinated waters containing bromide.

Summary: This study investigated the distribution of several trace metals between five size fractions in the Krka River estuary. The results showed that the river was the dominant source for some metals, and dilution effect was observed for others. The truly dissolved fraction dominated certain metals, while others were mostly present in larger particles. The percentage of colloids varied with river flow, and this estuary had a limited input of terrigenous material compared to other coastal areas.

Summary: Observations and modeling were used to assess the potential impacts of sediment releases from dam removals on the Hudson River estuary. It was found that the main sediment load comes from side tributaries, and fine-grained sediment deposits spread broadly along the estuary while coarser sediment deposits near the source, with transport distance inversely related to settling velocity.

Summary: The benthic impact of aquaculture waste is influenced by the accumulation and flow of waste around and below the farm. A study on an oyster aquaculture farm in the Damariscotta River found that despite slightly higher sediment erodibility at the farm compared to a downstream site, similar biogeochemical fluxes, geochemical properties, and macrofaunal communities indicated minimal impact on benthos. The study also observed microalgal mat presence and partial failure under high shear velocity, but suggested that peak bottom velocities during spring tides may periodically clear under-farm sediment of recent deposits.

Summary: The efficiency of cold vapor generation (CVG) method for sample introduction in mercury (Hg) isotope analysis and its impact on Hg isotope analysis have been investigated in this study. The efficiency of Hg CVG can be affected by the sample uptake rate, sample matrix, and the design of the gas-liquid separator (GLS). Matrix separation, optimal GLS design, and tuning the sample uptake rate are crucial for obtaining high accuracy and precision in Hg isotope analysis.

Summary: This study used a three-dimensional sediment numerical model to investigate the water and sediment transport in Hangzhou Bay. The results showed that in summer, there were southward and westward flows from the Changjiang Estuary, with stronger intensity during the spring tide. The bottom water and sediment transport patterns were similar to the surface patterns. In winter, the transport patterns were similar to those in summer but weaker.

Summary: This study isolated microplastics from soils collected from the Kavir and Lut Deserts on the Iranian plateau, with most of them having a fibrous nature and being composed of polyethylene terephthalate and Nylon. The majority of microplastics are likely brought into these desert environments from distant sources via wind, undergoing rapid transport, internal recycling, as well as significant photo-oxidation and mechanical weathering.

Summary: This study investigates the tissue-specific bioaccumulation, release, and genotoxic response of tritiated stainless steel particles in marine mussels. The study finds that the particles rapidly accumulate in the mussel tissues, especially in the digestive gland, but are readily rejected and expelled over longer periods of time. The absence of genotoxicity suggests that the rapid processing of the particles and limited dissolution of steel components prevent chemical toxicity effects.

Summary: Abandoned boats are a growing problem in the coastal zone and have received limited attention. This study utilized Google Earth to remotely identify and gather information on abandoned boats in southern England. The survey revealed the presence of 266 abandoned boats mainly located in intertidal zones. The majority of these boats were made of timber and showed signs of damage and water-sediment ingression. The environmental impacts are expected to be significant, especially where clustered on protected mudflats.
