"Cyanobacteria are photosynthetic bacteria that are found naturally in lakes, ponds, wastewater treatment plants, and other surface waters. Blooms of cyanobacteria can introduce undesirable taste and odour compounds in water resources, but more importantly, toxigenic cyanobacteria produce a wide range of secondary metabolites known as cyanotoxins which can have serious adverse health effects on humans and animals exposed to them. Toxigenic cyanobacteria are one of the main health risks associated with water resources and consequently the analysis, control and removal of cyanobacteria and cyanotoxins from water supplies is a priority research area."-- |
