Toxicity of Potassium Permanganate and Potassium Peroxymonosulfate Controlled Released Biodegradable Polymer to the Non-target Organism Daphnia Magna

otassium permanganate (KMnO4) and potassium peroxymonosulfate (OxoneRTM) are chemical oxidants widely used in natural surface waters and wastewaters for the control and removal of pathogens and the prevention of disease caused by bacteria. However, KMnO4 and Oxone RTM have the ability to be toxic to aquatic life. Moreover, there is limited information within literature about the toxicity of these oxidizing agents to non-target organisms such as the microcrustacean Daphnia magna (D. magna). The purpose of this study was to evaluate the acute toxicity of KMnO4 and OxoneRTM to D. magna . The focus for this work is to determine the toxic effects on non-target organisms using the U.S. EPA approved Whole Effluent Toxicity (WET) Test performed with D. magna. Controlled Release Biodegradable Polymers (CRBP) were produced by encapsulating KMnO4 and OxoneRTM in polycaprolactone (PCL) per U.S. Patent...
