The concentration of benzene in urban air in the Tri-City area of Poland (GdaA"sk-Sopot-Gdynia, and Tczew) was assessed using diffusive passive samplers (Radiello). Samples were collected during a four-year monitoring campaign (2007-2010) at selected monitoring stations managed by the Agency of Regional Air Quality Monitoring in the GdaA"sk Metropolitan Area (ARMAAG) Foundation. The performance of the passive samplers was investigated in a field study that measured the benzene concentration in urban air. The results obtained by the Radiello samplers were compared with the results obtained using an on-line monitor (Chrompack CP 7001). Statistical analysis of the results obtained by the two different techniques (passive and on-line) was performed by a linear regression method (Student's t-test). The influence of temperature fluctuations on the uptake rate behavior of the passive samplers was also investigated.
