ClO2: Chlorine dioxide is a strong oxidizing agent that is added to
water as a disinfectant and to control taste and odour. Chlorine dioxide rapidly
decomposes into chlorite, chloride, and chlorate.
Guidelines for drinking water
Chlorine dioxide does not occur naturally in the environment but is
synthetically manufactured. It is used as a bleach at paper manufacturing plants
and as a water disinfectant. Due to its high reactivity, chlorine dioxide
released does not remain in the environment for a substantial period of time.
