Chemical characterization of PM2.5 (major and trace elements) was carried out for a source apportionment study of PM2.5 at a traffic site in Constantine, Algeria, from March 2017 to March 2018. For this purpose, several tools were used of which PMF, CPF, PSCF, Spearman correlation matrix and HYSPLIT back trajectories. The mean annual concentration...

L'exposition aux particules fines en suspension dans l’air provoque des effets délétères sur la santé, en particulier dans les centres urbains où les niveaux de pollution sont souvent élevés, particulièrement aux abords des routes où le trafic est dense. Une estimation quantitative et qualitative des émissions de PM2.5 est une condition préalable à...

Measurements of Saharan dust (SD) inputs are very scarce in the vicinity of the Saharan desert. This work aims to identify Saharan dust intrusions and evaluate their contribution to annual and daily PM10 at an urban background site located in the city of Constantine in Algeria. A reliable identification of SD days was carried out using aerosol maps...

This study presents for the first time, the results of a one-year measurement campaign on ambient PM10 (particulate matter with aerodynamic diameter less than 10 μm) at an urban site at Zouaghi, in the south of Constantine, Algeria. The main objective of this work was to provide PM10 mass concentrations, a chemical characterization of atmospheric p...

In order to assess the significance of PM in ambient air, it is necessary to evaluate their physical and chemical characteristics as well as identify their major emission sources. On a global scale, particulate matter in the atmosphere arises mainly from the combustion process of motorized vehicles, but natural sources are still considered as the m...

In general, much of the air pollution that has adverse impacts on human health and the environment today is the result of anthropogenic activities. Road traffic has led to increase in many air pollutants to levels around the world. It is considered as one of an important source of particulate matter in Africa. Information on PM concentrations and i...

Effluent from industrial activities or tannery textile printing often have a significant pollutant load dye readily biodegradable. Decontamination by conventional techniques is ineffective in some cases. In this work, we studied two separate processes for the elimination of a synthetic dye called Orange II. In the first part, we are interested in t...
