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: 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: A novel electrolysis biofilter (EBF) was developed for efficient degradation of MC-LR in contaminated water, meeting the WHO drinking water quality standard. Electrolysis, adsorption, and biodegradation were found to play important roles in the degradation process. LC-HRMS analysis revealed the degradation pathway of MC-LR.

Summary: In this study, a ternary Bi2O3/CQDs/rGO photocatalyst was successfully synthesized and exhibited excellent photocatalytic performance. It was found that the synergistic effect of peroxymonosulfate activated by photogenerated electrons and photocatalysis significantly enhanced the degradation efficiency of tetracycline hydrochloride, and the photocatalytic mechanism was verified through experiments.

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: 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: Irrigation with cyanobacteria-polluted water can lead to the migration of microcystins (MCs) from the soil surface to deeper layers, posing a potential risk to groundwater safety. This study evaluated the sorption, degradation, and leaching behavior of microcystin-LR (MC-LR) in soils amended with biochar and peat. The results showed that both biochar and peat can enhance MC-LR sorption in the soils, but they have contrasting effects on MC-LR biodegradation. The findings contribute to our understanding of the environmental fate of MC-LR in soils and have implications for groundwater protection in cyanobacterial-polluted areas.

Summary: Microsphere-like bismuth vanadate mesocrystals were synthesized using a simple solvothermal method and applied to the photocatalytic degradation of microcystin-LR. The results showed that these mesocrystals exhibited enhanced photocatalytic activity and stable dispersion and photostability during the degradation process. This study is significant for the development of efficient methods for removing microcystins.

Summary: Developing heterostructure photocatalysts for removing Microcystin-LR (MC-LR) under visible light was significant for water quality and risk control. Bi2WO6/Reduced graphene oxide (RGO) nanocomposites were prepared and achieved high removal efficiency and stability in degrading MC-LR. The degradation of MC-LR involved active species such as holes, hydroxide radicals, and superoxide radicals, and the introduction of RGO prevented the recombination of photoelectrons and holes.

Summary: This study demonstrated the anti-fibrotic effect of microcystin-RR on bleomycin-induced pulmonary fibrosis rodent models, attenuating pulmonary inflammation, collagen deposition, and fibrotic markers expression. Microcystin-RR treatment also reduced the number of pulmonary M2 macrophages and inhibited epithelial-mesenchymal transition and fibroblast-myofibroblast transition triggered by M2 macrophages. These findings suggest that microcystin-RR is a promising candidate for therapeutic and prophylactic strategies against idiopathic pulmonary fibrosis.

Summary: This study investigated the adsorption performance of three COFs for different MC derivatives, revealing different adsorption efficiencies for different toxins. By selecting COF functional groups, specific compounds can be selectively targeted or excluded, providing insights for the design of more efficient and selective adsorbent materials.
