Freshwater harmful algal blooms (HABs), caused mostly by toxic cyanobacteria, produce a range of cyanotoxins that threaten the health humans and domestic animals. Climate conditions anthropogenic influences such as agricultural run-off can alter onset intensity HABs. Little is known about distribution spread freshwater Current sampling protocols in some lakes involve teams researchers collect s...

As global climate change continues and the vegetation period lengthens, importance of research into cyanobacterial recruitment biomass associated toxin risks is growing. While most studies focus on planktonic cyanobacteria causing blooms, benthic have been less explored. This study reports for first time mass proliferation epilithic macrocolonies cyanobacteria, Gloeotrichia cf. natans, in water...

BACKGROUND The Salton Sea (SS) is the largest inland body of water in California: surface area 980 km2, volume 7.3 million acre-feet, 58 km long, 14-22 km wide, maximum depth 15 m. Located in the southeastern Sonoran desert of California, it is 85 m below sea level at its lowest point. It was formed between 1905 and 1907 from heavy river flows of the Colorado River. Since its formation, it has ...

To date, most research on freshwater cyanotoxin(s) has focused on understanding the dynamics of toxin production and decomposition, as well as evaluating the environmental conditions that trigger toxin production, all with the objective of informing management strategies and options for risk reduction. Comparatively few research studies have considered how this information can be used to unders...

BACKGROUND Microcystins LR (MC-LR) are hepatotoxic cyanotoxins that have been shown to induce reproductive toxicity, and Hypothalamic-Pituitary-Gonadal Axis (HPG) is responsible for the control of reproductive functions. However, few studies have been performed to evaluate the effects of MC-LR on HPG axis. This study aimed to investigate the MC-LR-induced toxicity in the reproductive system of ...

Cyanobacteria are a growing concern in the province of Quebec due to recent highly publicised bloom episodes. The health risk associated with the consumption of drinking water coming from contaminated sources was unknown. A study was undertaken to evaluate treatment plants' capacity to treat cyanotoxins below the maximum recommended concentrations of 1.5 microg/L microcystin-LR (MC-LR) and the ...
