研究了地表水中常见的抗菌添加剂三氯生（5-氯-2-（2,4-二氯苯氧基）酚）的直接光解作用。研究发现，2,8-二氯二苯并-对二恶英（2,8- dcdd）在缓冲水和自然水（密西西比河）中都有产生，在各种条件下的产率从1%到12%不等。这一结果表明，三氯生可能在阳光照射的地表水中转化为2,8- dcdd。(C) 2003 Elsevier Science B.V.版权所有
The direct photolysis of triclosan (5-chloro-2-(2,4-dichlorophenoxy)phenol), an antimicrobial additive commonly detected in surface waters, is studied. It is found that 2,8-dichlorodibenzo-p-dioxin (2,8-DCDD) is produced in both buffered and natural (Mississippi River) water with yields ranging from 1 to 12% under a variety of conditions. This result indicates that triclosan is likely converted to 2,8-DCDD in sunlight-irradiated surface waters. (C) 2003 Elsevier Science B.V. All rights reserved.
