The chronic exposure of large segments of the population to disinfected drinking water has necessitated an evaluation of the health effects of the by-products of the chlorination process. This paper reviews the available information concerning the reproductive consequences associated with exposure to disinfection by-products. Four groups of compounds are discussed: the trihalomethanes, in particular chloroform; the chlorinated phenols; chlorinated humic substances; and the haloacetonitriles. In the pregnant female, chloroform and the 2- and 2,4-chlorophenols produced low levels of embryo- and fetotoxicity. Chloroform induced terata when administered by inhalation. The chlorinated humic substances and 2,4,6-trichlorophenol were without significant reproductive effects. The haloacetonitriles showed in utero toxicity, becoming more severe with increasing halogen substitution.
大部分人口长期接触经过消毒的饮用水,因此有必要评估氯化过程副产物对健康的影响。本文综述了与接触消毒副产物相关的生殖后果的现有信息。讨论了四类化合物:三卤甲烷,特别是氯仿;氯代酚;氯化腐殖质;以及卤代乙腈。在怀孕雌性动物中,氯仿以及2-氯酚和2,4-二氯酚产生了低水平的胚胎毒性和胎儿毒性。通过吸入给予氯仿会诱发畸形。氯化腐殖质和2,4,6-三氯酚没有显著的生殖影响。卤代乙腈表现出子宫内毒性,随着卤素取代程度的增加而变得更加严重。
