Sensitivity of phytoplankton, zooplankton and macroinvertebrates to hydrogen peroxide treatments of cyanobacterial blooms.

Addition of hydrogen peroxide (HO) is a promising method to acutely suppress cyanobacterial blooms in lakes. However, a reliable HO risk assessment to identify potential effects on non-target species is currently hampered by a lack of appropriate ecotoxicity data. The aim of the present study was therefore to quantify the responses of a wide diversity of freshwater phytoplankton, zooplankton and macroinvertebrates to HO treatments of cyanobacterial blooms.
