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.

The widespread use of water-soluble polymers (WSPs) like polyethylene glycol (PEG) and polyvinyl alcohol (PVA) across multiple industrial household uses has recently raised concerns about their environmental persistence potential toxicity to aquatic organisms. Despite being excluded from regulatory oversight, recent studies suggest possible ecological risks associated with sub-lethal exposures these polymers. In this context, study investigates the transgenerational effects PEG PVA on Daphnia magna, focusing both life-history parameters epigenetic modifications at environmentally relevant concentration 1 μg/L. Through continuous exposure experiments, spanning three generations (from F0 F3), "recovery" groups, where only parental generation (F0) was exposed, our results reveal significant reductions in number newborns reproductive exposed but not subsequent generations. This suggests a multigenerational plasticity through compensatory or acclimation response over time. Global cytosine methylation patterns also showed initial increase PEG, which decreased later generations, indicating mechanism underlying observed effects. contrast, exhibited no changes life history global trend suggesting its likely influence. These findings underscore need for comprehensive risk assessments WSPs, particularly inducing long-term (epigenetic) effects, influencing functions how increased may affect responses against novel other stressors.
