Project Summary: In this study, scientists will test 60 combinations of six different methods for removing harmful cyanobacteria (blue-green algae) from water. These methods include using chemicals like titanium dioxide and hydrogen peroxide, as well as ultraviolet light. By studying how these methods affect three types of tiny aquatic animals called zooplankton (Daphnia magna, Daphnia pulex, and Ceriodaphnia dubia), researchers can find the best ways to reduce cyanobacteria without harming other organisms in the water. They will first do experiments in the lab, and then apply the safest and most effective methods to larger, controlled outdoor settings called mesocosms. This research could help to develop better ways to control harmful algal blooms and protect aquatic ecosystems while ensuring the safety of other living organisms in the water.
