Summary: Cyanobacteria have been part of the human diet for thousands of years. They thrive in certain environmental conditions and their consumption can have health benefits. However, cyanotoxins produced by cyanobacteria can pose risks to human health, particularly when contaminated water is used in food production.

Summary: The study team developed an LC-HRMS/MS method for comprehensive detection of anatoxins (ATXs). The method was applied to samples of benthic cyanobacterial mats and laboratory cultures, leading to the discovery of several new ATXs. These new ATXs are mainly formed through nucleophilic addition reactions, similar to microcystins.

Summary: Cyanobacteria produce cyanotoxins, which are a global issue in water leading to environmental degradation and potential toxic effects on humans and animals. The main route of human exposure is through oral intake, increasing the risk to public health. This review focuses on the genotoxic effects of well-known cyanotoxins and their underlying mechanisms.

Summary: This review covers the diversity and geographical distribution of potential microcystin-producing and non-microcystin-producing cyanobacterial taxa in Africa. The lack of information and large-scale studies have hindered the understanding of cyanobacteria occurrence and genetic diversity in African aquatic ecosystems. Researching cyanobacteria species from the African continent is urgent in order to effectively safeguard public and environmental health.

Summary: Invasive nostocalean cyanobacteria (INC) are rapidly spreading globally due to climate change, and they require continuous monitoring for water resource management because of their high toxin production potential. However, their morphological similarity to other nostocalean cyanobacteria makes them difficult to analyze under a microscope. This study used quantitative gene analysis to calculate the gene copy number per cell and assessed the presence of INC and their toxin production potential in the Nakdong River.

Summary: As drinking water treatment plants face intermittent blooms of cyanobacteria, new methods are needed to remove cyanotoxins. This study examined the effects of preoxidation treatments on the susceptibility of cyanobacterial cells to mechanical shear. The results suggest that chlorine and permanganate can increase susceptibility to shear in different types of cyanobacteria, potentially leading to delayed toxin release.

Summary: Cyanotoxins produced by cyanobacteria pose significant threats to human keratinocytes, inhibiting proliferation and migration, and causing cytotoxic effects. Among them, CYN and its decomposition products exhibit strong inhibitory effects on keratinocytes, while ANTX-a shows lower toxicity, requiring higher concentrations and longer exposure. Further research on cyanotoxins should focus on their decomposition products and ecotoxicology in natural aquatic environments.

Summary: This study invented an iron-based coupled process of moderate preoxidation-hybrid coagulation, which effectively removes cyanobacterial cells and metabolites and alleviates filter unit fouling. It provides a better alternative for cyanobacterial removal in drinking water treatment plants.

Summary: The study investigated the use of woven polypropylene covers and copper sulfate formulation to prevent algal growth in water treatment plants. The covers effectively suppressed algal growth, while the copper sulfate formulation had little impact. Only a small fraction of cyanobacteria contained genes for producing the microcystin toxin in the system.

Summary: Nutrient-driven cyanobacteria blooms are increasingly common in freshwater environments, especially in anthropogenically altered landscapes. This study focused on stormwater retention ponds in urban and suburban areas, which are likely environments for harmful cyanobacteria blooms. The investigation assessed the taxonomic composition, bloom morphological composition, toxicity, and impact of nutrients and other environmental factors. The results showed that cyanobacteria blooms, especially potentially toxic genera, were most prevalent in the water column of stormwater retention ponds. The study also identified the presence of harmful cyanobacteria in various other freshwater environments.

Summary: The study found that prehydrolyzed coagulants containing polymeric and/or cationic aluminum species are more effective in removing organic matter from water sources compared to conventional metal salt coagulants. In acidic conditions, ferric sulfate outperformed aluminum-based coagulants, while aluminum chlorohydrate was repeatedly noted as the best option in more alkaline conditions. Alum offered a good compromise between DOC and turbidity removals in neutral pH range.

Summary: The study investigated the microbial contribution to disinfectant decay in drinking water distribution systems using a batch test procedure. A modified method for determining the critical threshold residual (CTR) was developed, which can more easily be applied to distribution system scenarios. Four types of decay curves were identified, which could distinguish differences in the microbial contribution to disinfectant residual decay.

Summary: Microplastics are a complex issue in water systems due to their diverse physical and chemical characteristics. This study investigated the removal of carboxylated polystyrene microspheres in real surface waters, finding that higher alum doses generally led to better removal of smaller microspheres, but no substantial improvement in removal of particles between 3 and 25 μm. Smaller PS microspheres were more effectively removed in both river and lake water sources, with the water source significantly affecting the removal efficiency.

Summary: This study investigates the effects of natural organic matter (NOM) and hardness on the galvanic corrosion of lead in the presence of dissolved inorganic carbon (DIC) and pH. The results show that Suwannee River NOM significantly increases the release of dissolved lead in water samples, while hardness and DIC have no significant effect on lead release. The study also finds that the pH level plays a role in lead release, with higher pH levels resulting in lower lead release.
