Abstract: Harmful algal blooms (HABs) have been recognized as global phenomenon that can have devastating consequences: they produce cyanotoxins or accumulate biomass that alter the food web dynamics, adversely impacting the health of humans, livestock and wildlife. As a result, it is a national interest to prevent, control and mitigate HABs. Currently there are no effective treatment methods for in situ and simultaneous treatment of cyanobacteria and cyanotoxin. As eutrophication worsens in water bodies due to excessive nutrients discharge from anthropogenic activities, it is imperative to develop an effective in situ treatment method that can inactivate cyanobacteria and degrade cyanotoxins simultaneously, without deleterious impacts on the aquatic ecosystem. The goal of this proposal is to conduct proof-of-concept experiments to demonstrate the feasibility of an in situ approach to treat harmful algal blooms (HABs), where cyanotoxins and cyanobacteria are simultaneously degraded and deactivated. The technical objectives of this proposal are to test commercially available and experimentally synthesized TiO2 and Fe catalytic nanoparticles for cyanotoxin degradation and cyanobacteria inactivation, immobilize nanoparticles on a polymer fiber net, and evaluate a nanoparticle-polymer fiber net for in situ treatment of cyanotoxins and HABs.
