我们研究活动的目的是开发一种基于电子鼻的系统，用于在特定受体处连续监测环境气味，即直接在气味存在的地方进行监测。本文介绍了采用的实验方法，以使用三个电子鼻连续监测的气味从污水处理厂，其目的是确定其气味对邻近土地的影响。这项工作的重点是理论原则和实验方法，通过识别，定义和优化的程序，创建一个合适的训练数据集，最大限度地提高电子鼻的操作定性分类和估计周围空气的气味浓度的能力。应用三种电子鼻对位于意大利北部的一家废水处理厂的气味排放进行连续监测的结果，使我们能够得出一些关于受监测工厂气味影响的重要结论，并从更普遍的角度得出关于使用电子鼻作为气味影响确定工具的可能性的结论，展示了如何及时训练电子鼻可以成功地应用于连续监测气味的环境利益。(c)2007 Elsevier B.V.保留所有权利。
The aim of our research activity is the development of a system, based on the use of electronic noses, for the continuous monitoring of environmental odours at specific receptors, i.e. directly where the presence of odours is lamented. This paper describes the experimental approach adopted in order to use three electronic noses for the continuous monitoring of odours from a wastewater treatment plant, with the aim of determining its odour impact on the neighbouring land. This work focuses on the theoretical principles and the experimental methods adopted for the identification, the definition and the optimization of the procedures for the creation of a suitable training data set, which maximizes the electronic nose capability of operating a qualitative classification and estimating the odour concentration of ambient air. The results of the application of three electronic noses to the continuous monitoring of odour emissions from a wastewater treatment plant located in the North of Italy allowed to draw some important conclusions about the odour impact of the monitored plant and, from a more general point of view, about the possibility of using electronic noses as odour impact determination tools, showing how opportunely trained electronic noses can successfully be applied for the continuous monitoring of odours of environmental interest.
