What causes an HAB or Dead Zone?
What types of organisms are involved in cyanobacteria?
They are one of very few groups of organisms that can convert inert otmospheric nitrogen into an organic form, such as nitrate or ammonia. Cyanobacteria blooms in the united states have been associated with the death of wildlife and domestic animals. They may pose a risk to human health through the exposure to contaminated freshwater, the ingestions of contaminated drinking water, or the consumption of contaminated fish or shellfish.
