  • Iron based sustainable greener technologies to treat cyanobacteria and microcystin-LR in water

    The presence of the toxic cyanobacteria and cyanotoxin, microcystin-LR (MC-LR) and other cyanotoxins, in drinking water sources poses a serious risk to public health. Iron based technologies using magnetic zero-valent iron nanoparticles (nZVI) and ferrate ion (FeVIO42−, Fe(VI)) represent greener approaches to remove cyanobacteria and degrade MC-LR in water. This paper reveals ...

  • Algal blooms in drinking water reservoirs

    Drinking water reservoirs worldwide often suffer from frequent outbreaks of algal blooms. Their water quality degrades and becomes undrinkable. Algal blooms can grow so massive that they are even visible from outer space. Rising temperatures, extreme weather, stagnant water, and excess of nutrients accelerate algae growth. On hot summers, algae can grow very fast ...

  • Impacts of Climate Change on the Occurrence of Harmful Algal Blooms

    Climate change has been occurring naturally as well as caused by anthropogenic activities over the decades. In relation to the fresh and marine water, the concentration of greenhouse gases results in temperature rise of surface water, lower pH and changes to precipitation, evaporation and vertical mixing of water. All these consequences of changing the environment in combination with excessive ...

  • Vulnerability of Quebec drinking-water treatment plants to cyanotoxins in a climate change context

    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 μg/L microcystin-LR (MC-LR) and the ...

  • Algal blooms: What are they?

    Algal blooms are also known as marine blooms or water blooms, and are actually a sudden increase in the population of algae in water scenery. Algal blooms usually take place in freshwater, such as lakes and water reservoirs as well as in marine milieus. They can be easily identified by coloration of the water ensuing from the high density of pigmented cells. Though many types of algae can form ...
