In order to investigate the potential role of mussels as a vector of influenza A viruses, we exposed zebra mussels (Dreissena polymorpha) to natural lake water containing a low pathogenic H5N1 avian influenza virus. Mussels were kept in water containing virus for 48 hr, then transferred into fresh water for another 14 days. Virus detection in mussels and water samples was performed by quantitative real-time reverse transcriptase-PCR (qRRT-PCR) and egg culture methods. Virus uptake was detected in all of the mussel groups that were exposed to virus. Even after 14 days in fresh water, virus could still be detected in shellfish material by both qRRT-PCR and egg culture methods. The present study demonstrates that zebra mussels are capable of accumulating influenza A viruses from the surrounding water and that these viruses remain in the mussels over an extended period of time.

In freshwater lakes and rivers, cyanobacteria belonging to the family Leptolyngbyaceae bore > 1 mm deep into limestone pebbles by dissolving carbonate at the tip of their 3-8 μm-thick filaments. The abundance of these borings decreases downward while it is so high at the rock surface that micrometric debris is formed. Moreover, the disintegrated material on the pebbles' surface can be easily removed, for instance, when pebbles are grinding against each other due to wave or current action or when insect larvae settle and scratch loosened grains from the surface while constructing their cases.

Lithium (Li) has become essential for energy and digital transitions, especially as a component of rechargeable batteries. Its growing uses worldwide lead to increasing anthropogenic releases of Li into the environment, which is making Li as an emerging contaminant. It is thus critical to evaluate the ecotoxicological impact of Li, which has been poorly studied unlike its human toxicology.

The presence of sub-micron-sized plastics in the environment has been increasing, with the possible risks of these particles remaining relatively unknown. In order to assess the toxicity of these particles, 100 nm diameter green fluorescent nano-polystyrene spheres (NPS) (20-60 mg/L) were exposed to zebra mussels () to investigate the mortality, clearance rate and stress-related biomarker responses. were collected and analysed with standard OECD toxicological tests and biomarker analysis to detect both physical and biochemical responses after exposure to NPS.

Sertraline is one of the most widely prescribed antidepressants, worldwide detected in rivers, thus raising concern about its ecotoxicology. However, there is knowledge gap on its pharmacokinetics and pharmacodynamics in freshwater bivalves. Comparative biology can help to gain in understanding and improve our ability to assess ecotoxicological risks in a wide range of species.

Article Synopsis
- Zebra mussels are invasive species that can change aquatic ecosystems and food webs, potentially increasing mercury levels in fish, yet their impact in inland lakes hadn't been previously studied.
- In Minnesota lakes with zebra mussels, adult walleye and yellow perch showed mercury levels 72% and 157% higher, respectively, compared to lakes without them, with young fish also having elevated mercury concentrations.
- These higher mercury levels in invaded lakes raise concerns for fisheries management and human health, especially since many walleye exceeded safe consumption thresholds more frequently than in uninvaded lakes.
