Special Issue Information

Dear Colleagues,

The dynamics of air quality parameters in term of physical/meteorological features and molecular composition of the gaseous and particulate components determine human, biocenotic, and material exposure to different chemical mixtures and potentially health impacts and stress to objects and devices. Moreover, the variability of exhaled volatile compound profiles reflects physiological processes in the humans, animals and plants.

Sensor and chemosensor systems allow high-frequency acquisition of air samples and multiparametric profiles related to air composition. Data flows are thus produced describing linear and nonlinear phenomena that can be related to atmospheric chemical and photochemical reactivity. Efficient and validated procedures for data processing, pattern recognition, anomaly detection, classification, prediction and forecasting need to be applied.

Industrial source apportionment by receptor modeling for air quality management, pattern detection, and recognition for instrumental odor monitoring systems/e-noses are some of the applications. Breath analysis is a further related research field.

This Special Issue on “Chemometric Tools for Monitoring Air Type Profiles” aims at collecting recent advances in the development and validation of data handling tools for providing relevant information from multisensor devices, characterizing air type profiles. Research related to nonlinear phenomena, machine learning, data fusion, indoor monitoring, and long-term monitoring is welcome.

Odour emissions are a global issue that needs to be controlled to prevent negative impacts. Instrumental odour monitoring systems (IOMS) are an intelligent technology that can be applied to continuously assess annoyance and thus avoid complaints. However, gaps to be improved in terms of accuracy in deciphering information, especially in the implementation of the mathematical model, are still being researched, especially in environmental odour monitoring applications. This research presents and discusses the implementation of traditional and innovative parametric and non-parametric prediction techniques for the elaboration of an effective odour quantification monitoring model (OQMM), with the aim of optimizing the accuracy of the measurements. Artificial neural network (ANN), multivariate adaptive regression splines (MARSpline), partial least square (PLS), multiple linear regression (MLR) and response surface regression (RSR) are implemented and compared for prediction of odour concentrations using an advanced IOMS. Experimental analyses are carried out by using real environmental odour samples collected from a municipal solid waste treatment plant. Results highlight the strengths and weaknesses of the analysed models and their accuracy in terms of environmental odour concentration prediction. The ANN application allows us to obtain the most accurate results among the investigated techniques. This paper provides useful information to select the appropriate computational tool to process the signals from sensors, in order to improve the reliability and stability of the measurements and create a robust prediction model.

Odour emissions generated by industrial and environmental protection plants are often a cause of nuisances and consequent conflicts in exposed populations. Their control is a key action to avoid complaints. Among the odour measurement techniques, the sensory-instrumental method with the application of Instrumental Odour Monitoring Systems (IOMSs) currently represents an effective solution to allow a continuous classification and quantification of odours in real time, combining the advantages of conventional analytical and sensorial techniques. However, some aspects still need to be improved. The study presents and discusses the investigation and optimization of the operational phases of an advanced IOMS, applied for monitoring of environmental odours, with the aim of increasing their performances and reliability of the measures. Accuracy rates of over 98% were reached in terms of classification performances. The implementation of automatic correction systems for the resistance values of the measurement sensors, by considering the influence of the temperature, has been proven to be a solution to further improve the reliability of IOMS. The proposed approach was based on the application of corrective coefficients experimentally determined by analyzing the correlation between resistance values and operating conditions. The paper provides useful information for the implementation of real-time management activities by using a tailor-made software, able to increase and enlarge the IOMS fields of application.
