Abstract

The city of Agadir is one of the best tourist destinations in Morocco, considered as one of the most beautiful bay in the world, which has a port infrastructure and strong industry based on the processing of seafood which often implicated as the source of odors. In order to identify in real time the sources responsible for the odors experienced in the city center and to act quickly in conjunction with industry, the Wilaya of Souss Massa Draa Region has implemented a continuous odor monitoring and tracking system using electronic noses. The treatment of meteorological data and data sent by electronic nose enables atmospheric dispersion modeling, which allows to follow instantly the odor level in the study area and to identify the sources responsible for odors with receiving warning of incidents odors, data analysis system generated every four minutes allowed to have results confirmed by companions of questionnaires to nearby residents. To reduce odors, recommendations have been suggested, which is to set up affordable and efficient practices.
