Harmful Algal Blooms. algal bloom. Blue-green algae or cyanobacteria, are a natural part of a healthy water ecosystem. However, in the summer when the water

Cyanobacterial blooms are usually blue-green in color, but algal blooms can vary in color, ranging all the way to red or brown. When a bloom occurs, scum (a layer of foul extraneous matter) might float on the water surface, resulting in a rotten plant-like odor. Blooms typically occur during late summer or early fall, but can occur anytime during the year. Not all algal blooms are harmful.

Blooms can form in warm, slow-moving waters that are rich in nutrients from sources such as fertilizer runoff or septic Cyanobacteria can form dense and sometimes toxic blooms in freshwater and marine environments, which threaten ecosystem functioning and degrade water quality for recreation, drinking water, Cyanobacterial blooms can severely damage water ecosystems, causing fish and plants to suffocate and die. They compromise the water quality and safety for animals and people by releasing Cyanotoxins into the water. When the Cyanobacteria in the bloom start to disintegrate, they produce unpleasant tastes and odors. Economic impacts. CyanoHABs can bring economic losses to many business sectors.

In freshwater, the majority of HABs are caused by cyanobacteria (also called blue-green algae). However, cyanobacteria blooms may still occur. Therefore, continue to be vigilant and avoid contact with pond water that is scummy or discolored and may have a strong odor. If you see a suspicious cyanobacteria bloom, notify your local health department. Additionally, a photo noting the location, day and time can be sent to cyano@apcc.org.

Cyanobacteria are the Earth's oldest oxygenic photoautotrophs and have had major impacts on shaping its biosphere. Their long evolutionary history (∼3.5 by) has enabled them to adapt to

A bloom essentially takes over parts of a body of water, or a full body of water, and changes the way in which the ecosystem functions. Although some blooms occur naturally, others are caused, in part, by human activities.

While often a green or blue-green colour, they can also be white, brown, blue, yellow-brown, or red. If conditions are suitable, cyanobacteria can increase to excessive levels and form visible ‘blooms’ which can lead to poor water quality and the potential for toxicity. 2019-10-23 · Algal blooms can be harmful to people and animals.
