There are several factors that cause the toxicity to go up or to be lower, such as: stress factors, contact, if the cyanobacteria are alive or dead, the movement of the water, the currents, the level of sun light, level of decomposition, stress exerted on dead or live cyanobacteria. The list goes on and on, more research has to be carried out regarding this issue. So far, both positions are probably right. One of the first studies of these uncommon cyanobacteria was carried out by the Guatemalan Scientist Pablo Mayorga and his results confused a lot of people and were considered inconclusive. But Mayorga’s analys
