Hydrogen peroxide has one extra unstable atom of Oxygen which when mixed in water just raises the Oxygen available in the water and nothing harmful as such.
I put a tablespoon of 40% Hydrogen peroxide per gallon of water, then sprinkle and water the plants with it. Also raises the free Oxygen available to the roots.
Don't know what your exact question is but that should guide a bit.
