本powerpoint演示文稿首先介绍了研究目标:确定土壤 还有各种各样的霉味 水取决于环境 背景水基质和/或 氯的存在或 氯胺。实验设计包括以下内容: 6.水源； 通过8种不同方案采集16份水样= 128个FPA分析； 使用风味面板分析来检测气味 氯、泥土、发霉和泥土/发霉；和 实验因素包括 脱氯（处理）， MIB污染物添加，以及 Geosmin污染物添加。提出了一个统计模型，以及固定的影响:总氯气味；土味-（Geosmin=20.1-61.9纳克/升）；霉味（MIB=18.6纳克/升）；（Geosmin=20.1-61.9纳克/升）和（MIB=18.6） ng/L）-（MIB=霉味）。结论表明:有显著的统计学结果 表现出对泥土气味的掩蔽 在饮用水中氯和土工蛋白之间 水位（20。 1-61.9纳克/升）； 氯掩盖了泥土的气味。 掩盖霉味是不可取的 这项实验意义重大 饮用水水位设计（18.6纳克/升）；和 使用气味面板的其他测量值 分析误差较小的评估。包括表格、数字。

This powerpoint presentation begins by presenting the research objective: to determine if the levels of earthy and musty odors in various waters are dependent on the background water matrix and/or the presence of chlorine or chloramines. The experimental design included the following: 6 water sources; 16 water samples by 8 different protocols = 128 FPA analyses; used Flavor Panel Analysis to detect odors Chlorine, Earthy, Musty and Earthy/Musty; and, Experimental Factors included dechlorination (Treatment), MIB contaminant addition, and Geosmin contaminant addition. A statistical model is presented, along with fixed effects for: total chlorine odor; Earthy Odor - (Geosmin = 20.1 - 61.9 ng/L); Musty Odor (MIB = 18.6 ng/L); (Geosmin= 20.1-61.9 ng/L) & (MIB = 18.6) ng/L) - (MIB = Musty Odor). Conclusions indicate that: there are significant statistical results showing MASKING of Earthy Odors between Chlorine and Geosmin at drinking water levels (20.1 - 61.9ng/L); Chlorine hides the earthy odor. masking of Musty Odors were not significant with this experimental design at drinking water levels (18.6 ng/L); and, use other measurements of odor panel evaluation that have less errors of analysis. Includes tables, figures.
