Exploring Spatial Variations in Dry Deposition and its Constituents with Respect to Industrial Facilities

Laura Megido, Rosa Lara, L. Negral, Yolanda Fernández-Nava et autres

Abstract As a consequence of industrial activities, significant quantities of settleable particulate matter (SPM) are transferred to surrounding areas. This study was carried out in Gijón (Spain), where industries coexist very closely with populated areas. The objective was to assess the variation …

Analysis of the abundance and impacts of volatile organic compounds across Europe

Xiansheng Liu, Minghan Wang, Taicheng An, Xun Zhang et autres

Urban volatile organic compounds (VOCs) are key precursors of tropospheric ozone and secondary organic aerosols (SOA), yet their long-term dynamics and health implications remain unclear across Europe. Here, we synthesize two decades of VOC observations (2002–2023) from 21 urban monitoring sites in …

Meteorological influence on atmospheric dry deposition in rural and suburban areas: Implications for the health of agricultural land workers

Beatriz Suárez-Peña, Laura Megido, Rosa Lara, L. Negral et autres

This study investigates potential health risks for agricultural land workers by ingestion, inhalation and dermal contact with metals (Al, As, Cd, Co, Cu, Fe, Mn, Pb, Sb, Sr, V, Zn) present in the dry deposition of settleable particulate matter (DSPM). It compares …

Changes in PM10 concentrations, composition, and source contributions in the last decades in urban and regional Barcelona

Anna Canals-Angerri, Philip K. Hopke, Rosa Lara, Andrés Alástuey et autres

PM 10 concentrations in Europe have been declining in the last decades. An analysis of the PM 10 concentrations and speciation measured at an urban and a regional background sites in NE Spain (BCN and MSY, respectively) is carried out with data …

Causes of the unremitting high ambient levels of PM10 in a suburban background site in NE Spain

Anna Canals-Angerri, Marta Via, Rosa Lara, Andrés Alástuey et autres

Atmospheric PM10 and benzo(a)pyrene (BaP) concentrations in Manlleu (NE Spain) have remained high from 2008–2023, frequently exceeding EU limit/target values, and reaching BaP levels up to six times higher than urban averages in Spain. Furthermore, PM speciation campaigns were carried out in …

Measurement report: Exploring the variations in ambient BTEX in urban Europe and their environmental health implications

Xiansheng Liu, Xun Zhang, Xun Zhang, Marvin Dufresne et autres

BTEX (benzene, toluene, ethylbenzene, and m -xylene, p -xylene, and o -xylene) are significant urban air pollutants. This study examines BTEX variability across 7 European countries using data from 22 monitoring sites in different urban settings (urban background, traffic, industry, and suburban …

Exploring the variations in ambient BTEX in urban Europe and its environmental health implications

Xiansheng Liu, Xun Zhang, Xun Zhang, Marvin Dufresne et autres

Abstract. BTEX (benzene, toluene, ethylbenzene, m,p,o-xylene) are significant urban air pollutants. This study examines BTEX variability across seven European countries using data from 22 monitoring sites in different urban settings (urban background, traffic, industry, and suburban background). Results indicate that the relative …

Variability of ambient air ammonia in urban Europe (Finland, France, Italy, Spain, and the UK)

Xiansheng Liu, Rosa Lara, Marvin Dufresne, Lijie Wu et autres

This study addressed the scarcity of NH3 measurements in urban Europe and the diverse monitoring protocols, hindering direct data comparison. Sixty-nine datasets from Finland, France, Italy, Spain, and the UK across various site types, including industrial (IND, 8), traffic (TR, 12), urban …
