近年来，有报道表明，在水处理过程中使用二氧化氯（Cl02）代替氯气作为预氧化剂，在某种程度上与客户家庭和企业产生令人厌恶的气味有关。这些气味用“煤油状”、“猫尿状”和“强含氯”等术语来描述在从处理厂和家庭采集的水样中分离和识别导致气味的化合物的尝试没有成功。其他人认为，令人厌恶的气味在某种程度上与家庭和企业中新地毯的存在有关，这为进一步的实验提供了基础。研究得出的主要结论是，强烈的含氯气味是由Cl02本身引起的，而煤油状和cat- 尿样气味是从水中释放出来的Cl02与客户住宅内空气中的有机物之间的气相反应产物。包括13个参考文献，表1。

In recent years, reports have indicated that the use of chlorine dioxide (Cl02) instead of chlorine as a preoxidant during water treatment is somehow related to the production of offensive odors at customers' homes and businesses. These odors were described by terms such as "kerosenelike," "cat-urine-like," and "strong chlorinous." Attempts to isolate and identify the odor-causing compounds in water samples taken from treatment plants and homes were unsuccessful. Suggestions from others that the offensive odors were in some way related to the presence of new carpeting in homes and businesses provided the basis for additional experiments. The principal conclusions derived from the study are that the strong chlorinous odors are caused by Cl02 itself, whereas the kerosenelike and cat-urinelike odors are products of gas-phase reactions between Cl02 liberated from the water and organic substances in the air inside the customer's residence.
