Notas: The present study arises from the collaboration in the project of Atmospheric deposition in natural and anthropized environments of the northeast of Spain; Integrated geochemical-magnetic characterization (DONAIRE project), coordinated by the Geological and Mining Institute of Spain and financed by the Ministry of Economy, Industry and Competitiveness. The aim is to quantify and characterize spatialtemporally atmospheric deposition fluxes, based on geochemical measurements and environmental magnetism, in 12 sites spread across Navarre, Aragon, Catalonia and the Balearic Islands, a broad region with contrasting environmental and socioeconomic gradients. The study period covers June to December 2016, in which about 20% of the days there was influence of air masses with Saharan dust in suspension. Two episodes of severe Saharan dust intrusion have been identified, in addition to other atmospheric episodes of interest. These severe events caused abrupt increases in deposition rates, especially in Aragon, in addition to increasing magnetic susceptibility, which is generally greater in urban areas than in nearby remote referents but which during these severe events tends to be more uniform. Polluting sources of anthropic origin predominate in the entire study area, especially in peninsular sites. In total, four anthropic sources have been identified (traffic, industry, combustion of fuel oil and agricultural emissions mixed with other industrial sources) and three natural sources (Saharan dust, regional dust and marine aerosol). Finally, a study of the ecotoxicological effects of the atmospheric deposition on the bacterial community of the soil has been carried out, which confirms in concrete cases this influence on the carbon degradation capacity of the microbial community.
