Summary: This study demonstrates that solar irradiation can enhance the reduction of mercuric Hg(II) to elemental Hg(0) by algal cells and their organic matter. Algal organic matter (AOM) was found to be more effective in reducing Hg(II) than algal cells themselves due to cell surface adsorption and uptake of Hg(II) inside the cells under solar irradiation. Additionally, sunlight facilitated the transformation of Hg to less bioavailable species compared to species formed in algal cells in the dark. These findings highlight the important functional roles and potential mechanisms of algae in Hg reduction and immobilization under varying lighting conditions.

Summary: Understanding the uptake and fate of mercury compounds in biota is crucial for understanding the global mercury cycling and its transfer through food chains. This study analyzed mercury concentrations in Scottish birds of prey and found the presence of mercury selenide nanoparticles in the liver of some golden eagles, which has not been observed in terrestrial birds of prey before. The study suggests that these nanoparticles may be formed as a detoxification mechanism or accumulated through foraging on stranded cetaceans or seabirds.

Summary: Both inorganic and organic fertilizers increase the concentration of methylmercury (MeHg) in rice grains, but through different mechanisms. Inorganic fertilizers enhance mercury methylation by increasing the bioavailability of mercury and the relative amount of Hg-methylating microbes. In contrast, organic matter in organic fertilizers is the main driver for the increase in MeHg concentrations in rice grains and can also immobilize mercury in soil.

Summary: The study found that atmospheric total gaseous mercury (TGM) was the main source of Hg accumulation in rice, while methylmercury (MeHg) concentrations in rice tissues were directly related to MeHg contents in paddy soil. Both atmospheric and soil Hg sources influenced the accumulation of inorganic Hg (IHg) in rice. Above-ground rice tissues were able to absorb IHg from the atmosphere and soil, with the potential for translocation to below-ground tissues.

Summary: The laboratory experiments showed that sea stars accumulated the highest concentrations of methylmercury and inorganic mercury in their digestive glands and pyloric caeca after being fed contaminated mussels for 49 days. Steady states were reached for both mercury forms in the sea stars during the 7-week feeding period, with concentrations approximately 1/2 and 1/4 of the levels found in the mussel food. Additionally, the sea stars eliminated inorganic mercury faster than methylmercury during a 140-day elimination period following the feeding period.

Summary: The biogeochemical cycling of mercury in aquatic environments is influenced by factors such as temperature, seasonal variations, bacterial activity, dissolved oxygen levels, and interactions with dissolved organic matter. This process leads to the reinsertion of mercury contamination from human activities into aquatic systems, particularly in toxic forms like methylmercury. Phytoplankton play a crucial role in the transfer of methylmercury to the aquatic food web, posing risks to human health through consumption of seafood. This review summarizes recent findings on the interaction between organic mercury forms and natural phytoplankton and highlights the need for further research to prevent mercury biomagnification under climate change and increasing pollution scenarios.

Summary: Growing evidence suggests that microorganisms exhibit heterogeneous sensitivity to toxicants, but the mechanisms behind this remain unclear. This study confirmed the heterogenous responses of Chlamydomonas reinhardtii to Cu stress, and found a link with the cell cycle. The increase in labile Cu(I) was related to cell division, leading to fluctuations in labile Cu(I) with diurnal and cell cycles. Cu influenced the cell cycle and algae at different cell phases exhibited different Cu sensitivities. This study reveals the underlying mechanisms of heterogeneous Cu sensitivity in phytoplankton and can help assess the ecological risks of Cu.

Summary: This study quantified the nonspecific interactions between three different functional polystyrene nanoplastics and zebrafish cells. The uptake of the nanoplastics in the cells peaked within 2 hours and then decreased, and the uptake rate was similar among the different types of nanoplastics but related to their functionality. The clathrin-mediated and caveolae-mediated pathways were mainly involved in the uptake process. The internalized nanoplastics were transported to lysosomes and exocytosed by the cells via energy-dependent processes. The estimated retention half-lives of the nanoplastics in fish cells were also determined.

Summary: Due to the COVID-19 pandemic, billions of people wear face masks daily, but the potential risks of hazardous materials released from these masks remain largely unexplored. This study evaluates the leachability and cytotoxicity of copper nanoparticles in face masks for the first time. The results show that inhalation of copper from the mask accounts for around 3% of the total copper, and a significant amount of copper attached to the fibers can be easily released into solution. The released copper causes cellular stress and oxidative damage. These findings underscore the need for careful assessment of the leaching of nanoparticles in face masks.

Summary: A two-compartmental toxicokinetic model is used to explain the interspecies sensitivity of imidacloprid to different aquatic invertebrates by distinguishing relevant levels of toxicity in organisms. The sensitivity to imidacloprid can vary significantly among different species. Internal levels of toxicity and toxicokinetic parameters are essential in understanding interspecies sensitivity. The model demonstrates that imidacloprid exhibits the highest toxicity to Chironomus dilutus, followed by Lumbriculus variegatus, Hyalella azteca, and Daphnia magna. The sensitivity of these invertebrates to imidacloprid varies by over 1000 times based on water concentrations, but decreases to around 50 times when based on internal residues, highlighting the importance of toxicokinetics in interspecies sensitivity. The two-compartmental model successfully simulates the slow elimination of imidacloprid in three species by distinguishing dynamic and toxicologically available fractions.

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.
