Conclusions
This study assessed the pollution levels reached by different sizes distributions of fine particles for the first time
in Algeria. The results showed that at the site, the mean atmospheric levels of PM-10, PM-3 and PM-1 were
75.2μg/m3, 40.3μg/m3 and 25.9μg/m3, respectively. These levels are excessive and greatly exceed the standards in
some countries. These particles are more harmful because over 50% of PM-10 are alveolar particles. Overall it was
found that air pollution by fine particles in Algiers is worrying from the levels recorded. The magnitude of this
pollution may be due to poor combustion as a result of older, poorly maintained, vehicles that are almost completely
devoid of catalytic converters and fuelled almost entirely with leaded petrol.
