Cyanobacteria, or blue-green algae, commonly occur in a variety of water types throughout the world. A high proportion of the cyanobacterial blooms and scums contain potent toxins. This volume looks at the application of biological, toxicological, biochemical and physicochemical techniques in studies of cyanobacterial toxins and at experimental methods that have identified at least 50 cyanobacterial compounds toxic to vertebrates.
