Abstract
An advanced monitoring station, equipped with a combination of DOAS system and classic monitoring devices, was set up in the urban background of Rome. An intercomparison between DOAS and gas-chromatographic technique for the measurement of the concentration level of benzene and toluene in the urban area has ben carried out. At the same time, an intercomparison between the DOAS and data provided by the chemiluminescent conventional analyzer has been developed to test the capability of DOAS system as a monitoring tool for secondary pollutants. The comparison between the data collected by the DOAS system and the conventional analyzer, provides quality assurance and reliability for the monitoring network and allows to understand the sources of the differences in instrumental responses. The results show that DOAS can be conveniently used for urban pollution monitoring.
