The scientific journal Atmosphere in its special issueAir quality Assessments and Management has published an article  by the title Impact of NOx and NH3 Emission Reduction on Particulate Matter across Po Valley: A LIFE-IP-PREPAIR Study.

The article is the result of ARPAE Emilia-Romagna, ARPA Piemonte, ARPA Lombardia and ARPA Veneto within LIFE PrepAIR modelling working group.

Different air quality modelling systems are used by the four regional agencies to assess the sensitivity of PM2.5 concentrations to the reduction of NOx and NH3 emissions with the aim of identifying both the most effective emission reduction strategies and analysing the non-linear effects on PM2.5 concentrations as the precursors vary.

The multi-model analysis shows that reductions in several emission sectors are necessary to achieve optimal results. In addition, the non-linearity analysis showed that during the cold season, PM2.5 abatement efficiency tends to increase with increasing emission reductions, whereas during the summer, it remains almost constant or decreases slightly with increasing reductions.

OJAP Open Journal of Air Pollution has recently published the submission of PrepAIR’s partner ARPA Lombardia: a paper titled “Atmospheric Emission Sources in the Po-Basin from the LIFE-IP PREPAIR Project” by Alessandro Marongiu, Elisabetta Angelino, Marco Moretti, Giulia Malvestiti and Giuseppe Fossati.

The paper presents the focus on emission estimates in the Italian Regions of the Po-basin obtained by the development of a common air pollutant emission dataset on the Po-basin and Slovenia foreseen in LIFE PrepAIR project . The objective is to update emission inventories developed by the environmental protection agencies and regions of Lombardy, Emilia-Romagna, Piedmont, Veneto, Friuli Venezia Giulia, Valle d’Aosta, the province of Bolzano (participating as stakeholder) and the province of Trento. A data flux is defined considering the activities on emission estimates by the different administrations according to the current Italian legislation. This activity has allowed the completion of two different datasets on the area for 2013 and 2017.
