Abstract. In many large cities of Europe standard air quality limit values particulate matter (PM) are exceeded. Emissions from road traffic and biomass burning frequently reported to be the major causes. As a consequence these exceedances number plans, most them focusing on emissions reductions, have been implemented in last decade. spite this implementation, did not record decrease PM levels. Thus, is efficiency plans overestimated? Do contribute less than expected ambient levels urban...
Abstract. An analysis of chemical composition data particulate matter samples (TSP, PM10 and PM2.5) collected from 2002 to 2008 in the North Atlantic free troposphere at Izaña Global Atmospheric Watch (GAW) observatory (Tenerife, Canary Islands) shows that desert dust is very frequently mixed with pollutants Saharan Air Layer (SAL). The study this set Median Concentrations At Receptor (MCAR) plots allowed identification potential source regions pollutants. Areas located south southern slope...
We offer an overview of the COVID-19 -driven air quality changes across 11 metropolises in Spain with focus on lessons learned how continuing abating pollution. Traffic flow decreased by up to 80% during lockdown and remained relatively low full relaxation (June July). After a significant shift from public transport private vehicles (+21% Barcelona) persisted due pervasive fear that using might increase risk SARS-CoV-2 infection, which need be reverted as soon possible. NO2 levels fell below...

Abstract. The impact of road dust emissions on PM10 and PM2.5 (atmospheric particulate matter with diameteer < 10 μm 2.5 mass concentrations recorded from 2003 to 2010 at 11 locations (rural, urban industrial) in southern Spain was estimated based the chemical characterization PM use a constrained Positive Matrix Factorization, where profile local samples is used as priori knowledge. Results indicate that increased levels average by 21–35% traffic sites, 29–34% background sites heavily...
The source regions of dioritic and tonalitic magmas have been identified in a deep crustal section the Famatinian arc (Sierras Pampeanas western Argentina). zones intermediate igneous rocks are located at transition between gabbro-dominated mafic unit tonalite-dominated unit. In upper levels intruded into metasedimentary wall-rocks, crystallized mainly as amphibole gabbronorite caused partial melting surrounding metasediments. turn, leucogranitic melts sourced from newly but still hot layers...
Abstract. We interpret here the variability of levels carbonaceous aerosols based on a 12 yr database from 78 monitoring stations across Spain specially compiled for this article. Data did not evidence any spatial trends country. Conversely, results show marked differences in average concentrations cleanest, most remote sites (around 1 μg m−3 non-mineral carbon (nmC), mostly made organic (OC) with very little elemental (EC), around 0.1 m−3; OC / EC = 12–15), to highly polluted major cities...
We present the analysis of strongest North African desert dust (DD) intrusion that occurred over Iberian Peninsula (IP) during last decade, as registered by modern remote sensing techniques like Sun photometry. This event took place from 22 July to 3 August 2004. The most relevant features this exceptional event, originated Saharan desert, were its great intensity and duration. focus on columnar aerosol properties measured AERONET‐Cimel photometers at El Arenosillo (southwest) Palencia...
