Contribution To The Study Of Air Pollution Nearby Algiers By Polluting Gases Using A New Sampling Technique

Abstract: The study presents the level of air pollution by eleven polluting gases measured during six months in Draria (Algiers), a location influenced by the traffic emissions. The sampling of this pollution was done by a 24 hours and 7 days a week sampling station that we ourselves built based on an Arduino programmable board and a series of MQ-type sensors. During this study we have shown the interest of using such type of programmationin order to have an instantaneous evaluation of the air quality to allow making decisions about this pollution and take preventive measures and actions. The rate of benzene is on average lower than the international norms of 10μg/m3. The exploitation of the results has permitted to put into evidence the daily, weekly and monthly distribution of these polluting gases. The study of the compassrose and pollution rose has permitted to surround the most affected zones by the pollution. Various interrelationships between these polluting gases that have been established show that the benzene is a good indicator of the pollution by cars.
