A harmful algal bloom (HAB) is an algal bloom that causes negative impacts to other organisms via production of natural toxins, mechanical damage to other organisms, or by other means. The diversity of these HABs make them even harder to manage, and present many issues, especially to threatened coastal areas. [ 33 ]
Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
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 caused by cyanobacteria, which sometimes can produce toxins called cyanotoxins that can be harmful to pets and people. Health officials investigating possible algal bloom ...
And the ugly: Algal blooms like this one in Gorham last fall are why efforts are being made to gather data, spot trends and learn more about water quality and the health of Canandaigua Lake.
An algal bloom, sometimes referred to as a “red tide,” is a cluster of algae that forms when the water around it is warm, slow-moving and full of nutrients, according to the Centers for ...
Freshwater algal blooms are the result of an excess of nutrients, particularly some phosphates. [3] [4] Harmful algal blooms are algal bloom events involving toxic or otherwise harmful phytoplankton such as dinoflagellates of the genus Alexandrium and Karenia or diatoms of the genus Pseudo-nitzschia. is an algal bloom that causes negative ...
Blue-green algae, known as cyanobacteria or harmful algal blooms (HABs), has been confirmed at Devils Lake in Manitou Beach, a news release from the Lenawee County Health Department said.
