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.
摘要
含有已知量2,3,7,8 - 四氯二苯并 - 对 - 二噁英（TCDD）的除草剂制剂，在叶片、土壤或玻璃板上暴露于自然阳光下时，主要由于光化学脱氯作用，在一天内会损失大部分或全部的TCDD。尽管已知纯TCDD具有持久性，但在暴露于户外光照的稀薄除草剂薄膜中，它作为污染物并不稳定。
