Resum:

The chemical composition of the atmosphere has significantly changed in the last century, mostly due to increased emissions of gases and particles derived from human activities. Several studies have analyzed the trends in the chemical composition of rainwater and atmospheric deposition in recent decades in central and northern Europe. However, for Spain there is a lack of studies at national level. Up to now, analyses of decadal trends are only available from a few individual stations. In this paper we first present the different methods to measure atmospheric deposition. Then we compile a list of atmospheric deposition monitoring stations in Spain and review the available time series, for series longer than 10 years, with special attention to the trends of N, S and African dust. Finally, we indicate future research directions to fill the gaps in knowledge about patterns and trends of atmospheric deposition at a national level. © 2017 Los Autores. Editado por la AEET.

Resum:

Mediterranean Basin ecosystems, their unique biodiversity, and the key services they provide are currently at risk due to air pollution and climate change, yet only a limited number of isolated and geographically-restricted studies have addressed this topic, often with contrasting results. Particularities of air pollution in this region include high O3 levels due to high air temperatures and solar radiation, the stability of air masses, and dominance of dry over wet nitrogen deposition. Moreover, the unique abiotic and biotic factors (e.g., climate, vegetation type, relevance of Saharan dust inputs) modulating the response of Mediterranean ecosystems at various spatiotemporal scales make it difficult to understand, and thus predict, the consequences of human activities that cause air pollution in the Mediterranean Basin. Therefore, there is an urgent need to implement coordinated research and experimental platforms along with wider environmental monitoring networks in the region. In particular, a robust deposition monitoring network in conjunction with modelling estimates is crucial, possibly including a set of common biomonitors (ideally cryptogams, an important component of the Mediterranean vegetation), to help refine pollutant deposition maps. Additionally, increased attention must be paid to functional diversity measures in future air pollution and climate change studies to establish the necessary link between biodiversity and the provision of ecosystem services in Mediterranean ecosystems. Through a coordinated effort, the Mediterranean scientific community can fill the above-mentioned gaps and reach a greater understanding of the mechanisms underlying the combined effects of air pollution and climate change in the Mediterranean Basin. © 2017 Elsevier Ltd
