0332085 Hozalski The main goal of the proposed research is to determine the abiotic degradation pathways and kinetics for regulated (i.e. THMs and HAAs) and unregulated or iremergingle DBPs (e.g., haloacetonitriles, halonitromethanes, and haloketones) upon their reaction with iron metal, synthetic iron oxides, and pipe corrosion products obtained from full-scale distribution systems. The specific objectives are to:1) determine the kinetics and pathways of the degradation of DBPs in the presence of Fe(0) and Fe(0) corrosion products,2) evaluate the effects of dissolved oxygen and chlorine on DBP degradationrates in the presence of Fe(0) and Fe(0) corrosion products, and 3) determine the kinetics and pathways of the degradation of DBPs in the presence of pipe solids and in pipe sections collected from full-scale water distribution systems.

0332085 霍扎尔斯基 拟议研究的主要目标是确定受管制（即THMs和哈斯）和未受管制或未融合的DBP（例如，卤代乙腈、卤代硝基甲烷和卤代酮）与铁金属、合成铁氧化物和从全规模分配系统获得的管道腐蚀产物反应。具体目标是：1）确定在Fe（0）和Fe（0）腐蚀产物存在下DBPs降解的动力学和途径， 评估溶解氧和氯对Fe（0）和Fe（0）腐蚀产物存在下DBP降解率的影响，以及3）确定管道固体存在下和从全尺寸配水系统收集的管段中DBP降解的动力学和途径。
