International audience ; Nowadays, air pollution has a major impact on the environment and human health. Owen gauges allow the sampling of atmospheric depositions in polluted sites for further characterisation. This paper shows the study of the air particles of an old mining zone in Cartagena-La Unión (South-east of Spain) in order to quantify their potential risk on human health. There were 4 strategic sites monitored: the main mining tailing (Avenque), the urban area (La Unión), an agricultural zone (formerly mining) and a site in the Mediterranean coast. Physico-chemical and mineralogical characterisation was applied to atmospheric fallouts. The granulometry revealed a dust particle size around 15 μm, with the coarsest particles in the urban area and the thinnest at the tailing site. XRD analyses showed the presence of quartz, carbonates, sulphides and sulphates. Observations with SEM-EDX confirmed chemical spectra and allowed us to classify the particles into well-crystallised minerals and heterogeneous dusts. Total metal content determination was carried out by ICP-MS analyses and results showed Zn, Pb, As and Cd fluxes (respectively 2549, 1275, 68 and 7 μg·m-2·d-1) exceeding the limit values set by European legislations in the mining area. The fluxes of Zn, Pb and As also exceed these standards in the urban area whereas the coastal zone only exceeds the thresholds in the case of As. Inhalation health risk (defined by US EPA, 2009) was quantified in the sites using total and bioaccessible metal contents of the dusts. Risk calculations using total metal content considering a residential scenario showed acceptable risk for all sites except for the mining tailing which presented non-acceptable cancer and hazard risk mainly due to the total As and Pb contents. When considering the bioaccessible fraction of As and Pb, the risk diminished to acceptable values, demonstrating the overestimation produced when using total metal contents.

González, N. D., Nicolosi, A. P., Badenes, D., Decotto, L., Gómez, L., . Fuentealba, F. Transiciones de la escena audiovisual. Perspectivas y disputas. Bernal: Secretaría de Posgrado, Universidad Nacional de Quilmes. ; Es un libro que se permite reflexionar sobre las transformaciones que experimenta el escenario audiovisual en la actualidad. Y lo hace con una mirada que sintetiza la perspectiva de las distintas experiencias de construcción de conocimiento que atraviesan a la Universidad, en su ámbito de la comunicación audiovisual. Esto incluye: sus proyectos de investigación; los aportes de profesores y alumnos de las carreras de grado y posgrado vinculadas al tema; y los diferentes debates generados por las "Jornadas transversales de Televisión Digital" que año a año se desarrollan en la Universidad Nacional de Quilmes, convocando a importantes actores del campo disciplinar y del ámbito profesional audiovisual. En este sentido, este libro invita a expertos nacionales e internacionales a indagar en el mundo audiovisual desde la Legislación y la política pública audiovisual en Argentina y América Latina; desde nuevos géneros, formatos y pantallas; y desde aspectos tecnológicos como la interactividad. En un terreno dinámico y vertiginoso, una mirada atenta desde la Universidad pública sobre la comunicación que, más allá de quien la gestione, siempre será un tema de interés público y de debate para las democracias contemporáneas. ; Presentación / Néstor Daniel González; Alejandra Pía Nicolosi -- 1.
