Rosset Biología PCA Sfax atmospheric pollutants traffic and industrial sources particular meteorological conditions The descriptive study related to the evolution of O3, NO, NO2, CO, SO2, CH4, NMHC and PM10 concentrationsin downtown Sfax showed, during the period October 1996-June 1997, that the city is significantlyinfluenced by many sources and meteorological factors. The diurnal average concentrations of these specieslet appear at times some peculiarities due to the population local customs and also to particular meteorologicalconditions associated with predominant strong cyclonic situations (cut-off lows). Based on NO and CH4,two species selected respectively as local and synoptic tracers, this descriptive study which is refined by aprincipal component analysis showed, out from these particular meteorological conditions, three componentsof the atmospheric pollution: a first component formed by CH4 and in less degree NMHC showing theimpact of synoptic sources, a second component containing NO, NO2, CO, SO2 and in less degree PM10 andNMHC displaying the impact of local sources (vehicle and industrial sources), and finally a third componentconstituted by O3 and in less degree PM10 presenting the impact of regional sources. Under the above quotedcyclonic situations, the distribution of such components was shown considerably modified. 2007 artículo científico 0187-6236 https://www.redalyc.org/articulo.oa?id=56520301 en http://www.redalyc.org/revista.oa?id=565 Atmósfera application/pdf Universidad Nacional Autónoma de México Atmósfera (México) Num.3 Vol.20 |
