The present paper intends to discuss recent developments in detection and quantification of odorous compounds in real industrial gaseous emissions. In this work, the chemical characterization of industrial odours is carried out using an Agilent gas c

Dynamic olfactometry involves human examiners for quantifying odour. Examiners directly inhale, although diluted, the increasingly concentrated odorous samples and, during the analysis, they are thus exposed to substances potentially dangerous to hum

The sampling of odorous emissions is a fundamental step in correctly quantifying odour concentration. Its importance was strongly emphasized in the recent Italian legislation (MASE, 2023), which describes strict constraints for conducting olfactometr

Human examiners, known as panelists, are exposed to an unknown occupational exposure risk while determining odor concentration (Cod) using dynamic olfactometry. In the literature, a few papers, based on a deterministic approach, have been proposed to

An odour sample is generally a complex matrix consisting of numerous molecules (mostly volatile organic compounds, VOCs) chemically different from each other, and which can be perceived by the human nose. In order to chemically characterize this comp

Different techniques have been developed for the analysis of gaseous sulphur pollutants, to maximize the analytical signals. In a complex matrix, such as odorous emissions, the detection of sulphur compounds can be critical in GC analysis, due to the

Dynamic olfactometry is nowadays the most diffused technique to quantify odour emitted from industrial plants. The methodology, standardized by EN 13725:2003, involves human assessors, who are potentially exposed to hazardous pollutant present in odo

Nowadays, Volatile Organic Compounds (VOC) are a class of air pollutants increasingly studied in the scientific literature, due to the well-known impact on human health and the environment. They can be emitted from different sources, including variou

Refineries are characterized by relevant odour impacts, and the control and monitoring of this pollutant have become increasingly important. Dynamic olfactometry, a sensorial analysis that involves human examiners, is currently the most common techni
