Online the 2022 Air Quality Assessment Report for the Po Valley Basin and Slovenia

The 2022 Report of air quality assessment in the Po Valley Basin and Slovenia is now available for download.

The document is the result of the work of the group coordinated by ARPAE Emilia-Romagna and ARPA Piemonte, in which the environmental protection agencies of Lombardy, Veneto, Friuli Venezia Giulia and Slovenia (ARSO) participated, and is in addition to the 2020 and 2021 edition.

This third assessment report of action D5 provides a synthetic view on the state of air quality in the Po Valley and Slovenia for year 2022 and examines PM10, PM2.5, nitrogen dioxide and ozone, which are the pollutants whose concentration values more frequently exceed legislation thresholds. The assessment was carried out with data fusion techniques using model output and monitoring data collected within the PREPAIR project. Even though five CTM and data fusion modelling systems with different setup (resolution, boundary condition, meteorological data and data fusion technique) have been used, the model outputs are similar to each other. In this report the assessment methodology, the data fusion technique and results of the most critical indicators compared to the limit values established by the 2008/50/EC Directive are shown.
