abstract
electronic nose technology provides the attractive possibility of determining quantitative measurements of solid waste odors. this manuscript describes the results of efforts to use a cyranose 320 electronic nose to quantify odors at a landfill excavation site in the city of garfield heights, ohio as well as other solid waste related odors. sampling procedures developed to overcome problems of headspace dilution and background contamination, which were experienced in the field, are also discussed. results are presented to illustrate that under appropriate conditions, calibrations may be developed from raw electronic nose sensor data
which can be used to identify variable concentrations of a single odor as well as aid in differentiation between component odors from a mixed source.
电子鼻技术提供了确定固体废物气味定量测量的可能性。这份手稿描述了在俄亥俄州加菲尔德高地市的一个垃圾填埋场挖掘现场，使用一个cyranose 320电子鼻量化臭味以及其他与固体废物相关的臭味的结果。此外，还讨论了为解决现场经验丰富的顶空稀释和背景污染问题而制定的采样程序。结果表明，在适当的条件下，可以根据原始电子鼻传感器数据进行校准。它可用于识别单一气味的可变浓度，并有助于区分混合源中的组分气味。
