Measuring Cyanobacteria Toxins in the Great Lakes

University of Wisconsin-Milwaukee

Harmful algal bloom (HAB) monitoring has become a popular topic of research in limnology. While most monitoring efforts center on chlorophyll measurement, the real impacts of HABs are connected to the toxins produced by cyanobacterial blooms, which can be challenging to measure. Due to their impact on human health, establishing models that allow for the […]
