Abstract

This research investigates the novel hypothesis that wind-blown dust (i.e. aerosols), resulting from wetting/drying cycles in coastal soils along shorelines experiencing harmful algal blooms, can contain high concentrations of algal bloom-generated neurotoxins. Inhalation of these aerosols can trigger respiratory and/or cardiovascular responses in people living along the coast, negatively impacting their health. Testing the hypothesis involves a coordinated approach that uses water sampling and analysis for algal bloom toxins, air quality, and aerosol sampling and analysis, as well as the field deployment of high frequency soil redox sensors and real-time monitoring, sample processing, and outreach during bloom events. The study area selected is around Lake Erie and near the city of Toledo, Ohio which gets it drinking water from the Lake. This area has repeatedly been impacted by harmful algal blooms in recent years. The research team is interdisciplinary and includes involvement by an expert in soil geophysics. It also includes medical personnel, one of whom is an expert in lung inflammation and clinical translation and one who is an expert in high-resolution toxin analysis. The work also involves collaboration with the Great Lakes Center which is jointly funded by the National Science Foundation and National Institutions of Environmental Health Sciences. Broader impacts of the work include improving understanding of health conditions caused or exacerbated by harmful algal b
