For those that are concerned ...

For those that are concerned about algae toxicity, this is a great information source - http://www.ecy.wa.gov/Programs/wq/plants/algae/publichealth/GeneralCyanobacteria.html.  Yes, at times it can be harmful to humans, pets and wildlife and microcystin is the toxin produced by cyanobacteria that's causes the problem. It is well to note that when cyanobacteria is in the process of dying, it will release microcystin (toxin) and the treatment should look to ensure it eradicates all forms of the bloom, as live microcystin will continuation thereof. Our organisation (www.ages1.com) recently undertook assays at a laboratory in South Africa running a water source, from the Hartbeespoort Dam, a massive body of water with heavy metals, effluent and other pollutants - an ideal environment for cyanobacteria to grow. We used our advanced electrocoagulation - variable electro precipitation system in which an electrical charge is introduced into the water (no chemicals, filters), and the ionised water totally decimated the tough cell membrane. We used a hemocytometer to determine the presence of live cells, and the reading was total neutralisation. We are now taking this technology into fruit packhouses as the lab results also showed the total neutralisation of various forms of penicillium, a fungi prevalent in packhouses. Watch this space!
