摘要：This study is presenting pollution level in Bucharest, the sources being mainly the traffic or vehicles, that became in larger numbers every year. A new mobile laboratory is used which is able to monitor continuously PM2,5, PM10, NOx, NO, NO2, O3, CO, SO2 and BTEX. The diurnal variations are presented in different environmental conditions: rainy day and sunny day, to compare the results and to present which is the outdoor influence of meteorological conditions. Particulate matter is influenced by rain as well as other compounds like BTEX. Ozone production is influenced by the solar radiation, so it’s also an interesting comparison between the two studied cases. BTEX compounds are measured by a mobile chromatograph placed in the lab and presents for every 30min. the diurnal variations of toluene, benzene, m, p, o xylene and ethylbenzene.
