濁の原因ともなる。2. Description of the Related Art As the concentration of peracetic acid is higher, the disinfecting ability of the aqueous solution is improved. Currently, peracetic acid compositions having a high peracetic acid concentration of about 6% by weight have been marketed as general-purpose peracetic acid compositions. However, the acetic acid concentration in these peracetic acid compositions is high, and when used as a herbicide or the like, it is decomposed on the soil surface or in the soil, and generates a large amount of methane gas and carbon dioxide gas that cause global warming. Further, when the water flows out of the soil due to rainwater, the COD of river water or the like increases, which causes water pollution.
