溶解天然有机物（NOM）长期以来一直被认为是主要的有机物 消毒副产物（DBPs）的有机前体贮存库。因为诺姆 结构没有很好的定义，大多数DBP研究集中在 可识别的最终产品（如三卤甲烷、卤乙酸）。毒理学 有证据表明，其他尚未查明的弱势商业群体对大部分的死亡负有责任 消毒对人类健康的不利影响。有迹象表明 含氮化合物可能在这些效应中起着关键作用，尤其是高浓度的 膀胱癌的水平。这项正在进行的研究的目的是确定前体 以及最终产品DBP，这些DBP可能负责一些关键问题 氯化的致癌危险。这包括对文献的仔细分析， 以及一些使用含氮前体模型的实验室研究。条件 使用的方法与公认的DBP测试方法一致。下列的 在所需的氯接触期内，根据需要保存样品，并对其进行分析 主要DBP（THM、HAAs等）、总有机卤化物（TOX）和其他不受监管的 副产品。利用这些数据，提出了完整的降解途径。包括14个参考文献、表格和图表。

Dissolved natural organic matter (NOM) has long been acknowledged as the principal reservoir of organic precursors to disinfection byproducts (DBPs). Because NOM structures are not well defined, most DBP research has focused on the easily identifiable end products (e.g., the trihalomethanes, haloacetic acids). Toxicological evidence suggests that other, as yet unidentified, DBPs are responsible for most of the adverse human health effects attributed to disinfection. There are indications that nitrogenous compounds may play a key role in these effects, especially the elevated levels of bladder cancer. The purpose of this ongoing research is to identify precursors and end product DBPs that are likely to be responsible for some of the key carcinogenic hazards of chlorination. This includes a careful analysis of the literature, as well as some laboratory studies using model nitrogenous precursors. Conditions were used so as to be consistent with accepted DBP testing methodology. Following the desired chlorine contact period, samples were preserved as needed and analyzed for major DBPs (THMs, HAAs, etc.), total organic halides (TOX), and other unregulated byproducts. Using these data, full degradation pathways were proposed. Includes 14 references, tables, figures.
