Changes in PM10 concentrations, composition, and source contributions in the last decades in urban and regional Barcelona
PM<inf>10</inf> concentrations in Europe have been declining in the last decades. An analysis of the PM<inf>10</inf> concentrations and speciation measured at an urban and a regional background sites in NE Spain (BCN and MSY, respectively) is carried out with data from studie...

| Sumario: | PM<inf>10</inf> concentrations in Europe have been declining in the last decades. An analysis of the PM<inf>10</inf> concentrations and speciation measured at an urban and a regional background sites in NE Spain (BCN and MSY, respectively) is carried out with data from studies since 1999. Since 1999, the average PM<inf>10</inf> concentrations in BCN went from 49 to 20 μg m<sup>−3</sup> (−1.4 [−2.3, −0.29] μg m<sup>−3</sup> y<sup>−1</sup>, p < 0.05). Having met the EU PM<inf>10</inf> standards in 2010, mild actions were implemented to abate PM<inf>10</inf>, with local and regional efforts focusing on NO<inf>2</inf>. In 2020–2021, PM<inf>10</inf> was composed by 25 % of mineral matter (MM, 11 % desert dust +14 % urban dust), 22 % organic matter, 20 % secondary inorganic aerosols (SIA), 3 % elemental carbon, and 8 % sea salt (SS). Moreover, 19 % of PM<inf>10</inf> has a natural origin, being a relevant contribution for compliance of the PM<inf>10</inf> limit value (20 μg m<sup>−3</sup>) of the Air Quality Directive (EU) 2024/2881. Receptor modelling for 2020–2021 identified 10 major sources contributing to PM<inf>10</inf>: aged sea salt, mineral and vehicle emissions accounted for 81 % of the PM<inf>10</inf>. This study is the first in Barcelona not being able to identify a shipping profile. Despite substantial reduction of direct shipping emissions, moored cruise ships are identified as its primary PM<inf>10</inf> contributor. Overall, the results provide relevant information on the impact of policy actions implemented, and on identifying major target sources for the abatement of PM in urban environments of the W-Mediterranean. |
