Summary: Research on the parasitic interactions between freshwater mussels in the order Unionida and their host fishes has gained attention recently due to increased worldwide preservation efforts. The impact of these mussels on their hosts is generally minor, with effects varying depending on the species involved in the interaction. More studies are needed to understand the underlying mechanisms of these effects, as current research is biased towards a specific species and lacks molecular and genetic studies.

Summary: The glochidia of the freshwater pearl mussel show local adaptation by being more successful when attached to local salmonid strains. Therefore, conservation programs should prefer local, sympatric fish strains as hosts for captive breeding of juvenile mussels. Restoration of original salmonid populations is also important for promoting the recovery of endangered freshwater pearl mussel populations.

Summary: Freshwater mussels play crucial ecological roles but are endangered due to extirpation and reproductive failure. In this study, a species-specific eDNA assay was developed to monitor the abundance and winter reproduction of Buldowskia iwakawai. The correlation between eDNA concentration and mussel abundance was observed, and the eDNA concentration differed between gravid and non-gravid mussels. However, the increase in eDNA concentration was not detected during the glochidia release period.

Summary: The lampricides TFM and Niclosamide are used to control sea lamprey populations in the Great Lakes. Concern is growing over their potential risks to native freshwater mussels. This study evaluates the acute toxicity of TFM and TFM:NIC to mussel glochidia and adults, and assesses the behavioral and reproductive effects of lampricide exposure in gravid mussels. The results suggest that even short-term exposures to these compounds may have long-term cumulative effects on mussels.

Summary: Sea levels are rising globally, especially along the eastern coast of the United States. This can lead to saltwater intrusion into freshwater drainages, altering the salinity regimes and causing salinization of coastal freshwater ecosystems. The mixture toxicity effect of sea salt ions on freshwater mussels' early life stages is largely unknown. Acute toxicity tests conducted on three species of freshwater mussels showed that glochidia were more sensitive than juveniles to sea salt exposure. These findings are important for enhancing freshwater mussel conservation strategies in areas affected by climate-induced sea level rise and freshwater salinization.

Summary: The Grand River watershed in Ontario supports a diverse population of freshwater mussels, with ongoing recovery from historical lows reported in the 1970s. However, changes in mussel populations at specific sites appear to be linked to altered water chemistry, particularly in areas with point source pollution. Chronic exposure to high levels of major ions and discharges from industrial plants may be driving these changes and impacting sensitive biota beyond immediate receiving environments.

Summary: Road salt runoff is having a growing impact on water quality globally, particularly on freshwater ecosystems. This study focuses on the influence of road salt on an urban lake in Grand Rapids, Michigan. The research found that high chloride concentrations prevent complete mixing in the lake, leading to hypoxia in the deepest regions. Additionally, high phosphorus concentrations in the lake are likely to have accumulated over a long period of time. The study highlights the need for managing both internal and external sources of phosphorus and chloride in lake management actions.

Summary: Freshwater mussels are highly endangered due to the overuse of antibiotics, which has led to the emergence of antibiotic-resistant bacteria. These resistant bacteria increase the risk associated with the use of surface water and the spread of resistance genes. A study on two endangered freshwater mussel species revealed that coliform bacteria were present in both the water samples and the mussels, with the lowest concentration found at site T1. One of the mussel species, P. littoralis, faced the highest concentration of bacterial toxins, primarily from treated wastewater effluents and population centers. The bacteria isolates from this species showed resistance to multiple antibiotics, highlighting the importance of investigating management measures and water quality for freshwater bivalves.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
