title: Environmental degradation of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD).
abstract: Herbicide formulations containing known amounts of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and exposed to natural sunlight on leaves, soil, or glass plates lost most or all of the TCDD during a single day, due principally to photochemical dechlorination. Despite the known persistence of pure TCDD, it is not stable as a contaminant in thin herbicide films exposed to outdoor light.
