Revealing the Hidden Potential of Ultraviolet (UV)‐C Irradiation for Controlling Aquatic Toxicity Caused by Harmful Algal Blooms

Environmental Quality Management, Год журнала: 2025, Номер 34(3)

Опубликована: Фев. 7, 2025

ABSTRACT Harmful algal blooms (HABs) pose a significant threat to freshwater, brackish, and marine habitats. HABs have numerous harmful impacts, such as the creation of odorous compounds, disinfection byproducts, release toxic substances. Various physical, biological, chemical techniques been attempted prevent blooms. However, bulk management methods currently in use concentrate on emergent removals; result, these are usually less effective because they immobile. Ultraviolet (UV) irradiation has gained lots attention lately possible remedy for lowering HABs. In this review paper, we combined recent information about various effects blooms, UV‐C (UV‐C irradiation), starting from other used removal HABs, continuing with facilities, particularly flow‐through reactors, enabling development shipborne practical way through which technique was made remove Further, including mechanism, suppression factors, application technique, growth recovery. The UV‐induced damage nucleic acid, photosynthesis system, settleability, cell integrity, oxidative pressure were responsible density. factors needs be paid humic salinity, turbidity, nitrate, pH.

Health and Environmental Impacts of Cyanobacteria and Cyanotoxins from Freshwater to Seawater

Toxins, Год журнала: 2025, Номер 17(3), С. 126 - 126

Опубликована: Март 7, 2025

Cyanobacterial harmful algal blooms (cyanoHABs) are a natural phenomenon produced mainly by the interaction between and anthropogenic events. CyanoHABs characterized production of cyanotoxins that can have effects on different species within food web even affect human health. Among most prevalent toxin groups worldwide microcystins (MCs), anatoxins (ATXs), cylindrospermopsins (CYNs) nodularins (NODs), which as toxins with hepatotoxic, neurotoxic, cytotoxic effects. This review summarizes analyzes research influence cyanoHABs, main toxin-producing cyanobacteria in freshwater marine bodies, highlighting their global occurrence, toxicology, bioaccumulation dynamics vectors web, cases acute chronic intoxications humans. is useful for understanding cyanoHABs’ ecosystem impact health, how implementation surveillance management framework could generate vital information stakeholders to establish health guidelines risks hazards cyanoHABs

Water eutrophication leads to the frequent occurrence of cyanobacterial blooms, which pose a serious threat health and survival fish, top consumer in freshwater ecosystems. The hepatotoxicity induced by microcystin-LR (MC-LR) has been well studied; however, its impact on intestinal flora gut-liver axis rarely reported. This study aimed investigate harmful effects acute oral (303.89 µg/kg.bw) intraperitoneal (i.p., 101.3 exposure MC-LR intestine liver common carp. results showed that transaminase activity levels proinflammatory factors increased significantly, histological abnormalities were observed, indicating hepatoenteric inflammatory response. gram-negative bacteria increased, but expression bile acid (BA)-related genes (cyp7a1, cyp8b1, cyp27a1, fxr) short-chain fatty (SCFA) content decreased as LPS level increased. These suggest induces inflammation impairs BA synthesis, weakening defences promoting LPS-related hepatic inflammation. Additionally, permeability reduced SCFA synthesis can further compromise epithelium protection. was significantly more severe than intestine, recovery slower. enhances understanding environmental risks posed cyanobacteria.
