Researchers at a laboratory near Lake Erie are conducting studies to explore the potential health impacts of toxic algae blooms. The researchers are focused on understanding how harmful algal blooms can affect the health of individuals living in the vicinity of Lake Erie. Steven Haller, a clinical researcher at the University of Toledo’s Department of Medicine, was motivated to investigate this topic after witnessing the disruption caused by toxic algae in his community’s water supply a decade ago. The incident led to a two-day shutdown of the water supply, prompting Haller to seek answers regarding the health implications of such occurrences.
For residents in Lake Erie’s western basin, harmful algae blooms are a recurrent sight. The blooms are triggered by excess nutrients from farm fields being washed into the lake, promoting the growth of bacteria that can produce toxins harmful to humans and animals. Research has indicated that exposure to toxins such as microcystin from these bacteria can lead to illnesses in individuals who come in contact with contaminated water. Researchers at the lab managed by Haller and David Kennedy, an associate professor of medicine, are conducting experiments to understand how these toxins impact individuals, particularly those with underlying health conditions like asthma.
A new area of research being explored is the effect of aerosolized toxins, where the toxins become airborne. By exposing human lung cells to aerosolized toxins in controlled experiments, researchers aim to determine the inflammatory response in these cells. Monitoring the air quality near Lake Erie is crucial for assessing the potential aerosolization of toxins. Initial results from these experiments indicate increased inflammation in lung cells and a significant impact on individuals with asthma when exposed to aerosolized toxins.
Residents in the area have become accustomed to taking precautions against algae blooms, with some opting for bottled water amidst concerns about the water quality. Ongoing studies involve enrolling community members to evaluate if algal blooms have any discernible effects on their health. Over the next five years, researchers plan to conduct comprehensive health assessments on participants during the algal bloom season to better understand the potential health impacts. The goal is to provide insights into the relationship between algal blooms and health outcomes, offering valuable information to the community.
As researchers continue their investigations near Lake Erie, the findings from these studies will contribute to efforts aimed at safeguarding public health and raising awareness about the potential risks associated with toxic algae blooms in freshwater bodies.
