Hydrogen peroxide (H 2 O 2 ) occurs naturally
in fresh and marine waters
Important intermediate in redox processes
in chemical and biological aquatic systems
Acts as a strong oxidizing agent that reacts
with trace metals and pollutants
Elevated levels of H 2 O 2 have been shown to
cause damage and cell lysis in
microorganisms
Potential impacts on microbial water
