消毒剂/消毒副产品（D/DBP）规则将总有机碳（TOC）作为法规遵从性参数，其理念是TOC浓度是氯化后DBP形成可能性的直接指标。进行了一项综合研究，以评估两种最常用的方法（紫外线（UV）-过硫酸盐氧化和催化燃烧）测量水中TOC颗粒分数的能力，并确定该分数是否有助于DBP的形成。结果表明，燃烧法能更准确地测量天然水中的颗粒TOC含量。因此，水务公司用于评估通过水处理厂去除TOC的方法会显著影响法规遵从性和处理成本所需的化学剂量。 此外，氯化试验结果表明，DBP生成反应可能不受颗粒TOC的影响，因此作者提出，溶解有机碳而非TOC是水处理中DBP生成潜力的更合适指标。包括15个参考文献、表格和图表。

The Disinfectants/Disinfection Byproducts (D/DBP) Rule includes total organiccarbon (TOC) as a regulatory compliance parameter with the idea that TOC concentration is a direct indicator of the potential for DBP formation upon chlorination. A comprehensive study was conducted to evaluate the ability of the two most common methods, ultraviolet (UV)-persulfate oxidation and catalytic combustion, to measure the particulate fraction of the TOC in water and determine whether this fraction contributes to DBP formation. Results showed that particulate TOC fraction in a natural water was more accurately measured by the combustion method. Therefore, the method used by a water utility to evaluate TOC removal through a water treatment plant can significantly affect the chemical dosages required for regulatory compliance and treatment cost. Furthermore, chlorination testing results suggest that the DBP formation reactions may not be affected by particulate TOC, leading the authors to propose that dissolved organic carbon rather than TOC is a more appropriate indicator of DBP formation potential in water treatment.
