A harmful algal bloom (HAB), or excessive algae growth, sometimes called a red tide in marine environments, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to ...
A very large algae bloom in Lake Erie, North America, which can be seen from space. An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in fresh water or marine water systems. It is often recognized by the discoloration in the water from the algae's pigments. [1]

Amid concerns of algal blooms, the Ohio EPA reported Tuesday that 86% of the state's major rivers are meeting water quality standards.
In freshwater ecosystems, algal blooms are most commonly caused by high levels of nutrients (eutrophication). The blooms can look like foam, scum or mats or like paint floating on the surface of the water, but they are not always visible. Nor are the blooms always green; they can be blue, and some cyanobacteria species are coloured brownish-red.
Harmful Algal blooms are colonies of microscopic algae that grow out of control. They can be damaging to people, wildlife and the environment. How harmful algal blooms, or colonies of microscopic ...
The Ohio State Fair is one of the largest state fairs in the United States, held in Columbus, Ohio during late July through early August. As estimated in a 2011 economic impact study conducted by Saperstein & Associates; the State Fair contributes approximately 68.5 million dollars to the state's economy. [ 3 ]
Harmful algal blooms are caused by cyanobacteria, which sometimes can produce toxins called cyanotoxins that can be harmful to pets and people. Health officials investigating possible algal bloom ...
