Nutrient over-enrichment in freshwater environments, together with the on-going climate change, favour toxin-producing cyanobacteria bloom. Human health hazard may arise from drinking contaminated water. Additionally, cyanobacterial blooms affect other economic areas such as tourism, recreation, commercial fishery, water management and monitoring. Nowadays there is a scarcity of information on seasonal variations cyanotoxins various regions. Understanding historical trends variation patters foundation for forecasting will help to develop effective strategies. This review gives an overview cyanotoxins' analysis levels environments particular emphasis Europe. Recent analytical approaches are discussed patterns three major European zones (Mediterranean, continental, Atlantic) were distinguished. data multi-year studies showed tendency increasing levels.

Cyanobacteria produce a wide range of structurally diverse cyanotoxins and bioactive cyanopeptides in freshwater, marine, terrestrial ecosystems. The health significance these metabolites, which include genotoxic- neurotoxic agents, is confirmed by continued associations between the occurrence animal human acute toxic events and, long term, cyanobacteria neurodegenerative diseases.

Understanding the environmental conditions and taxa that promote occurrence of cyanobacterial toxins is imperative for effective management lake ecosystems. Herein, we modeled total microcystin presence concentrations with a broad suite predictors cyanobacteria community data collected across 440 Canadian lakes using standardized methods. We also conducted focused analysis targeting 14 congeners 190 lakes, to examine how abiotic biotic factors influence their relative proportions. Microcystins were detected in 30 % highest occurring most eutrophic located ecozones central Canada. The two commonly MC-LR (61 lakes) MC-LA (37 lakes), while 11 others more sporadically waterbodies. Congener diversity peaked Canada where biomass was highest.

Microcystin increased other less dominant taxa, as well copepod dissolved inorganic carbon water temperature. Collectively, these models accounted 34 70 variability, respectively.

Abstract The increasing global population has led to rising demand for food, particularly protein. As an excellent source of protein, fish play a crucial role in meeting this demand, making aquaculture highly impactful industry. Floating cages have been developed as method management and production achieve high productivity volume. However, these intensive farming practices can contribute eutrophication, leading changes primary producers promoting the excessive proliferation cyanobacteria. Cyanobacteria blooms pose significant consequences aquatic ecosystems, including potential risks exposed harmful cyanobacterial metabolites. Cyanobacterial metabolites encompass various chemical classes, such terpenoids, carotenoids, alkaloids, cyanopeptides, amino acids, organophosphates, macrolides, lipopolysaccharides. Some compounds' toxicity impact on farms still need be better understood. Cyanotoxins off‐flavour compounds water quality health hazards humans throughout food chain. Therefore, cyanobacteria economic, environmental, public implications. This review examines concerns associated with natural products farming, off‐flavours, known cyanotoxins, other potentially toxic compounds, while exploring their socioeconomic environmental risks.
