ETUDE DE LA POLLUTION DE L’AIR PAR LES TSP, LES PM ET ET LES METAUX LOURDS DU CENTRE D’ALGER

Abstract

This study consist in analyzing the quality of the air in the urbain site of Algiers Centre.A sampler with low and high air flow are used for the collection of the samples on the level of this site characteriezed by the presence of a strong density of circulation of cars.The mass of the ambient particles is a complex mixture which strongly depends on the characteristics of the sources and of their cuts according to whether they are ( fine particles) or( large particles).The procedures of the suspended particles in the air multiple are varied parmis them PM 10 and PM 2,5 wich are taken using a sampler of the type Gent sampler the analysis of the collected filtrs was carried out by two technique of spectrometry by x- ray fluorescence (XRF) and spectrometry inductively coupled plasma(ICP).Heavy metals such as : Ti, Cr, Mn, Fe, Pb, Zn, Cu, Ni are proportioned by this technique showing in obviousness the existence of an air pollution due mainly to the human activity. In what follows we have followed methodology and the results of the data processing of this pollution.
