Source apportionment of potentially toxic PM10 near a vast metallic ore mine and health risk assessment for residents exposed

Mining is an economic activity that traditionally releases large amounts of particulate matter into the atmosphere because of the procedures required to process the mineral. In particular, polymetallic ores are environmentally harmful as they can enrich potentially toxic elements, which may cause adverse effects to humans and ecosystems due to their toxicity. The aim was to assess the impact on health of this type of mining on nearby populations. Accordingly, it was conducted an extensive PM10 sampling campaign during the entirety of 2021 through a total of 248 filters placed in three villages close to the Rio Tinto district (Southwest Spain), which is one of the largest Cu mines in the world. A total of 58 major and trace elements were analysed, along with organic carbon/elemental carbon, cations, and anions. The mean PM10 concentrations were high during spring (47 μgPM10⋅m−3) and summer (56 μgPM10⋅m−3) in the population closest to the mine, wherein values surpassed the annual and daily limit values, but were lower in the other two villages. Moreover, high enrichment of As (annual maximum mean of 6.2 ng⋅m−3), Cu (70 ng⋅m−3), Pb (19 ng⋅m−3), and Zn (50 ng⋅m−3) was observed in all locations. A positive matrix factorization (PMF) was primarily used to assess the origins of this particulate matter, revealing that the impact of the mine reduced considerably over a long distance, with contributions ranging from 36% at the mine's outskirts to 8% further away from it, which coincides with the features of the mine during the abandonment phase (2001–2015). Despite this, the risk assessment revealed that the carcinogens were within the permissible exposure limits even in the closest village, indicating a minor concern for the inhabitants from a toxicological perspective.Funding for open access charge: Universidad de Huelva / CBUA

Libro de Actas de las III Jornadas ScienCity 2020: Fomento de la Cultura Científica, Tecnológica y de Innovación en Ciudades Inteligentes

Editorial: Kindle Direct Publishing, Seattle, WS (USA)Actualmente, nuestras ciudades están experimentando una verdadera transformación digital que requiere una atención inmediata en energía, transporte, movilidad, comunicación, seguridad, educación, turismo y aspectos sociales, así como fomentar todas aquellas actuaciones que persigan mejorar la calidad de vida y el desarrollo económico-ambiental sostenible. ScienCity es un foro científico-tecnológico que pretende dar a conocer a la sociedad los conocimientos y tecnologías emergentes siendo investigados en las universidades, informar de experiencias, servicios e iniciativas puestas ya en marcha por instituciones y empresas, llegar hasta decisores políticos que podrían crear sinergias, incentivar la creación de ideas y posibilidades de desarrollo conjuntas, implicar y provocar la participación ciudadana.Junta de Andalucía, Universidad de Huelva y Consejo Social de la Universidad de Huelv
