Are Warmer Waters More Toxic?

Cyanobacteria are an aquatic microorganism that releases a toxin known as microcystin, which can negatively impact water quality and endanger human health. They need sunlight and nutrients (such as nitrogen and phosphorus) to grow, but are dependent on other environmental factors such as water temperature. A research team in Ohio focused their research on how water temperatures affect cyanobacteria abundance and microcystin concentration in water. The results demonstrate that water temperature can be used to forecast cyanobacteria growth and toxin severity.
