| 摘 要： | 介绍了臭味层次分析法(FPA)培训内容及其在上海市饮用水臭味识别中的应用。结果表明,经过培训的FPA臭味识别小组能够对水样中不同种类的异臭味进行定性和定量的评价分析;臭味检测人员对上海市水体中含有的典型致臭土霉味物质甲基异莰醇-2和腥臭味物质二甲基三硫的嗅阈值可分别达到1.69ng/L和24.4ng/L,并对这两种物质的强度等级评价有较好的重现性。采用FPA评价上海市地区原水及不同供水区域自来水的臭味特征及加标后不同浓度条件下的臭味强度特征,结果表明,FPA优于现行使用的臭味评价方法,能够及时、快速地反映水质问题,是可靠的感官分析方法。 |

| Abstract: | Flavor profile analysis(FPA) training process and its application in drinking water in Shanghai City were introduced in this paper.The results showed: the trained FPA panel could identify and quantify the different kinds of odor in water;the odor threshold concentration of MIB and DMTS from musty and stench smell evaluated by the FPA panel could reach 1.69 ng/L and 24.4 ng/L respectively,and strengthen class evaluation recurrences for these two materials were good.FPA was also used to evaluate the odor inte... |
