Evaluation of atmospheric benzene concentrations in the Helsinki Metropolitan Area in 2000–2003 using diffusive sampling and atmospheric dispersion modelling (original) (raw)

This study evaluates atmospheric benzene concentrations in the Helsinki Metropolitan Area from 2000 to 2003 using both diffusive sampling and atmospheric dispersion modeling. Measurements indicated that while the annual mean benzene concentrations were generally below the European Union's upper assessment threshold, the lower threshold was exceeded at one urban station in 2000. The findings highlight the efficacy of combining empirical measurements with modeling techniques to assess urban air quality, with significant implications for traffic management and environmental policy.
