Residents near Lake Erie are familiar with the dangers of blue-green algae blooms, which can cause skin irritation, throat discomfort, and eye redness. Researchers are investigating the health impacts of inhaling airborne algae particles, led by David Kennedy, a professor at the University of Toledo. The ongoing study aims to understand how these toxins affect individuals’ health in the long term. So far, around 200 participants have contributed samples for analysis, shedding light on the varying responses to the toxins.
The study, known as the Great Lakes Aerosol Monitoring Research Study (GLAMR), focuses on individuals in the western basin of Lake Erie, regardless of nationality. The research team aims to identify people at higher risk of toxin sensitivity. Participants are providing samples during peak algae bloom periods and other times, including blood, urine, breath, and cell samples.
Airborne toxins from algae can travel significant distances and linger in the air for extended periods. Gregory Dick, from the University of Michigan, notes that these toxins can trigger symptoms akin to asthma, often referred to as the “August cough” by locals. While the long-term effects of inhaling algae remain unclear, experts emphasize the heightened sensitivity of lungs to airborne toxins compared to ingested ones.
The study seeks to define the movement of airborne algae, especially around Lake Erie’s flat topography, which aids in toxin dispersion. Andrew Ault, a chemistry professor at the University of Michigan, highlights the challenges of controlling airborne toxins compared to water pollutants. The research aims to provide communities with insights into potential air hazards and suggests precautionary measures such as using air purifiers during high-risk periods.
