The presence of aromatic hydrocarbon in atmosphere is due mainly to the emissions from autovehicular traffic and from domestic heating and to the fuel and solvent evaporation. The aromatic hydrocarbon concentration in the exhaust is strictly tied up to the fuel composition. In this communication the environmental levels of benzene, toluene and xylens measured inside an industrial site located to around 30 km from Rome in a cold (November) are reported and discussed. The industrial site is composed by a oil refinery, a waste plant and a cement facility and it is located between the sea (Tirrenean Sea) and the city of Rome. The monitoring of the benzene and of its homologues has been performed with a Differential Optical Absorption Spectrometer (D.O.A.S.) and a Mobile Laboratory equipped with automatic analysers and gas-chromatograph with FID detection (BTX). The results show like the meteorological aspects plays a fundamental role for the study of the examined site.
