Summary: Phytoremediation is a useful method for removing cyanotoxins from water, but its efficacy is influenced by the composition of cyanobacterial mixtures. This study found that while some plants can effectively reduce intracellular toxins and cyanobacterial biomass, they can also cause an increase in toxin concentration in the medium.

Summary: Lemna trisulca showed potential as a phytoremediation agent for reducing cyanotoxin concentrations in water through co-cultivation with different species of cyanobacteria, affecting their growth and development, and stabilizing water conductivity and pH values.

Summary: Lake Balaton, the largest shallow lake in Central Europe, is affected by the Zala River. The Kis-Balaton Water Protection System (KBWPS) was constructed to improve water quality, but toxic cyanobacterial blooms were still observed. The KBWPS acts as a significant buffering zone, protecting the water quality of Lake Balaton. Regular monitoring of cyanobacteria and cyanotoxins in this ecosystem is crucial.

Summary: This research investigated 24 water reservoirs in eastern Cuba and found that these reservoirs are affected by eutrophication, resulting in the growth of toxic cyanobacteria and the occurrence of microcystin-LR. The concentration of microcystin-LR detected in some of these reservoirs exceeds the limits set by the World Health Organization for drinking water.

Summary: This study utilized amplicon-based methods to assess the potential toxic cyanobacteria in Lake Utopia, Atlantic Canada, identifying Microcystis as the main taxa with toxigenic potential. The study highlights the importance of identifying cyanotoxin production potential by gene presence rather than species identity.

Summary: In this study, a novel anti-MC-LR/MC-LR/cysteamine-coated screen-printed carbon electrode biosensor was developed for rapid detection of microcystins in water. The biosensor showed excellent performance, with a linear working range and low limit of detection. It also demonstrated minimal interference from other common microcystins and coexisting ions in water. The biosensor offers an innovative and easy-to-use solution for in situ and low-cost detection, making it essential for smart environmental management systems.

Summary: The Lake in Central Park and Prospect Park Lake in New York City have extremely high levels of cyanobacteria and microcystin. These lakes have elevated levels of orthophosphate relative to dissolved inorganic nitrogen during summer months. Nitrogen consistently limits cyanobacterial populations while green algae are rarely nutrient limited. Adding public drinking water rich in phosphorus and to a lesser extent nitrogen significantly enhances the growth of cyanobacteria.

Summary: Research on light-driven oxidation technology for degradation of MC-LR has made progress, but there is still limited knowledge about the mineralization and detoxification of treated water as well as the fragments responsible for the toxicity of MC-LR.

Summary: The study reveals that exposure to cerium in Lake Taihu water can enhance the production of microcystins (MCs) in Microcystis aeruginosa, aggravating the pollution of MCs by promoting endocytosis in the cells of M. aeruginosa.

Summary: The research found that the most efficient elimination of Microcystis aeruginosa occurred in the chloride electrolyte due to the formation of active chlorine, causing intracellular damages and degradation of MC-LR. Additionally, the higher concentration of oxidants generated in the sulfate electrolyte compared to the phosphate solution explained the greater efficiency of electrochemical elimination in the sulfate system.

Summary: An efficient and eco-friendly electrochemical system was developed to purify water containing harmful cyanobacteria, allowing for rapid removal of algal cells and achieving high removal efficiencies. The system operates without chemical consumption, can function under a wide pH range, and demonstrates superior electro-adsorption for enhanced efficiency.

Summary: Lake Wilcox, located in southern Ontario, has experienced water quality deterioration due to urbanization and increased salinization associated with expanding impervious land cover. Water column stratification, phosphorus speciation, and algal abundance were identified as the main factors contributing to the changes in water chemistry. It is suggested that stricter controls on de-icing salt application and runoff should be considered to manage eutrophication symptoms in lakes of cold climate regions.

Summary: To ensure the safety of drinking water, it is important to understand the relationship between fungi and harmful cyanobacterial blooms (HCBs) and their toxins. This study found that the concentration of the fungus Cladosporium cladosporioides and the microcystin-gene transcript copy number of Microcystis aeruginosa appeared to be interrelated during each bloom season. The results also showed that there might be a balanced antagonism between the fungus and the cyanobacteria, with variations observed between different years.

Summary: This study introduces 5-AF and 6-AF as small-molecule fluorescent probes for the detection of MC-LR in cells and water samples based on fluorescence signal changes. Mathematical models were established to analyze the relationship between fluorescence intensity and MC-LR concentration. The mechanism and recognition principle of the probe response to MC-LR in natural lake water were comprehensively analyzed. These unique fluorescent probes may have the potential to detect MC-LR levels in vivo.
