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 with the potential to harm human health or aquatic ecosystems are referred to as harmful algal blooms or HABs. In freshwater systems, cyanobacteria (also called blue-green algae) are microorganisms that can produce HABs.

Recent research suggests that eutrophication and climate change are two processes that may promote the proliferation and expansion of cyanobacterial harmful algal blooms. Blue-green algae (Cyanobacteria) are photosynthetic bacterial organisms, naturally found in many types of water systems including lakes, rivers and wetlands.

2017-05-16 · “Cyanobacteria bloom” is a term used to describe the rapid growth of cyanobacteria, also called blue-green algae. 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.

Submitted: September 18th 2018 Reviewed: January 4th 2019 Published: April 3rd 2019. DOI: 10.5772/intechopen.84155 While most cyanobacteria blooms that appear minor will only have very low levels of toxins present, in other cases minor blooms may have higher concentrations of toxins.

Some common types of potentially toxic cyanobacteria are Microcystis, Anabaena, Planktothrix and Lyngbya. Microcystis. Freshwater and marine harmful algal blooms (HABs) can occur anytime water use is impaired due to excessive accumulations of algae. In freshwater, the majority of HABs are caused by cyanobacteria (also called blue-green algae).
