Lake Erie (/ ˈ ɪr i / EER-ee) is the fourth-largest lake by surface area of the five Great Lakes in North America and the eleventh-largest globally. [6] [10] It is the southernmost, shallowest, and smallest by volume of the Great Lakes [11] [12] and also has the shortest average water residence time. At its deepest point, Lake Erie is 210 ...
Lake Erie in October 2011, during an intense cyanobacteria bloom [1] [2] Microcystins—or cyanoginosins—are a class of toxins produced by certain freshwater cyanobacteria, commonly known as blue-green algae. [3] Over 250 [4] different microcystins have been discovered so far, of which microcystin-LR is the most common.
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.
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]
M. aeruginosa is favored by warm temperatures, [7] but toxicity and maximal growth rates are not totally coupled, [8] as the cyanobacterium has highest laboratory growth rates at 32 °C, while toxicity is highest at 20 °C, lowering in toxicity as a function of increasing temperatures in excess of 28 °C.
Stylobryon is a monotypic genus of golden algae in the family Dinobryaceae.It has one known species Stylobryon insignis Fromental, 1874. [1]Stylobryon has been found in numerous lakes, notably Lake Erie.
These include large lakes (Erie, Okeechobee) and small regional water masses like Ohio's Grand Lake St Marys. In 2014, detection of the microcystin toxin in treated water of Toledo (OH) resulted in a shutdown of the water supply to more than 400,000 residents.
Lake Erie has an excess of phosphorus due to agricultural runoff that quickens the growth of algae which then contributes to hypoxic conditions. [44] The superabundance of phosphorus in the lake has been linked to nonpoint source pollution such as urban and agricultural runoff as well as point source pollution that includes sewage and ...
