Abstract
In this paper the results of an air quality study in Rome are reported and the
contribution of no-methane and aromatic hydrocarbons to the ozone formation
have been investigated. The research has been carried out by means of an
intensive sampling campaign in January 1998, using both traditional methods of
analysis and sampling, and innovative methods for the determination of primary
and/or secondary pollutants and of traditional photochemical tracers, i.d. O3 and
NO2. In particular, about 30 no-methane and aromatic hydrocarbons have been
identified and quantified in 50 air samples collected by canisters and analyzed
by gas-chromatography, in the atmosphere of Rome; ozone, nitrogen dioxide,
formaldehyde and nitrogen monoxide have been determined by means of an
innovative method with high technology (Differential Optical Absorption
Spectrometry) and/or with analyzers on-line. The results obtained show that the
m-xylene, the toluene and 1,2,4-trimetilbenzene are the compounds that compete
in better percentage to the formation of ozone in Rome. The main pollution
source has been identified as the Liquefied Petroleum Gas leakage.
1 Introduction
The study of the atmospheric pollution has always impassioned the scientific
world for both the reasons linked to the knowledge of the chemical reactions
