ANN ARBOR, Mich. – Researchers at the University of Michigan have been awarded a $6.5 million grant to host a center for studying the links between climate change, harmful algal blooms and human health across the Great Lakes region.
According to school officials, harmful algal blooms are increasing due to increased precipitation, more powerful storms and warming Great Lakes waters.

Blue-green algae, also known as cyanobacteria, can produce toxins that are harmful to humans, pets and wildlife. While algal blooms are typically associated with Lake Erie, cyanobacterial harmful algal blooms (cHABs) now occur in all five Great Lakes.
Officials said the bacteria may look like spilled paint, scum, streaks, mats, or simply just discoloration. While the blooms are possible between May and October, they most often occur in August and September.
A person who breathes in or swallows water with cHAB toxins may experience runny eyes or nose, asthma-like symptoms, difficulty breathing, stomach pain, vomiting, diarrhea, weakness, headaches, and/or dizziness. cHAB toxins that come into contact with skin can cause rashes, blisters or hives.
The Great Lakes Center for Fresh Waters and Human Health, based out of Ann Arbor, will be assisted by scientists from the University of Toledo and the University of Michigan to focus on the human impact of cHABs. The center had previously determined that cyanobacterial toxins can become airborne when waves break against Great Lakes shorelines and piers.
The universities will collaborate on the first assessment of airborne cHAB toxins. More than 28 faculty researchers and dozens of students are expected to be involved.
The research findings will inform management strategies and public policies to protect drinking water and safeguard human health worldwide.
