Aqueous chemical reactions and the handling of chemicals used in drinking water treatment is the dominant source of environmental exposure to chlorate. Outside of exposure from drinking water treatment processes, the industrial uses of chlorate can lead to unsafe levels persisting in the environment. Chlorine dioxide, chlorite, and chlorate can occur in foods as they are used in flour processing, as decolorizing agents, as bleaching agents, and as an indirect additive from paper packaging.
