Electronic nose applications in environmental monitoring are nowadays of great interest,
because of the instruments' proven capability of recognizing and discriminating between a …

Continuous, in situ monitoring of air, water and land quality is fundamental to most
environmental applications. Low cost and non-invasive chemical sensor arrays provide a …

Odorous compounds from a landfill have been characterised by gas-chromatography–mass-
spectrometry, identifying about 100 volatile organic compounds. Air samples from different …

Quantification of odor emissions in wastewater treatment plants (WWTPs) is key to minimize
odor impact to surrounding communities. Odor measurements in WWTPs are usually …

Wastewater treatment plants have widely been described as a significant source of odour
nuisance, which has led to an increase of neighbourhood complaints. Therefore, to mitigate …

The interaction of polyphenols (tannins) with proline-rich proteins (gelatin) has been studied
using an automated flow injection system with Fourier transform infrared spectroscopic …

This paper proposes a novel data processing scheme for electronic noses that combines the
gramian angular field (GAF) and convolutional neural network (CNN) to achieve high …

Composting is a conventional but economical and environmentally friendly way to transform
organic waste into a valuable, organic soil amendment. However, the physico-chemical …

Gas sensor arrays have been used to identify gases based on their dynamic response. Pre-
processing of data plays a critical role in identifying different gases. There are several pre …

This review paper presents different ways to apply a measurement instrument of e-nose type
to evaluate ambient air with respect to detection of the odorants characterized by unpleasant …
