Odour impact assessment by Instrumental Odour Monitoring Systems: a case study focusing on the differentiation of different odour sources and performance testing

Abstract

The assessment of the odour impact associated to industrial activities represent one of the most interesting applications of Instrumental Odour Monitoring Systems (IOMS). Thanks to their capability of qualifying ambient air, IOMS can be effectively applied for the air quality monitoring directly where citizens complain about the presence of odours, i.e., the receptor. This paper describes the IOMS monitoring of a complex plant comprising a wastewater treatment plant (WWTP) and a plant for the storage, selection and pre-treatment of municipal and special wastes (WTP), focusing on the procedure used to train the IOMS and validate its detections.
