Evaluation of Ambient Air Odour Quality in Vicinity of Municipal Landfill Using Electronic Nose Technique

Abstract

The paper presents the results of investigation on ambient air quality evaluation with respect to concentration of odorants in a vicinity of municipal landfill. The investigation was carried out with a prototype of electronic nose and a team of panelists utilizing the Nasal Ranger field olfactometers. The prototype was equipped with a set of six semiconductor sensors by FIGARO Co. and one PID-type sensor. Performed measurements revealed that the prototype of electronic nose could be employed for determination of odorants concentration in ambient air; difference in mean values of odorants concentration obtained with both techniques was statistically insignificant in 75% of cases. The highest mean values of odorants concentration amounted from 12.5 to 36.7 ou/m3 depending on distance from the emitter, measurement direction and applied measurementtechnique.
