“…The main human activities and industries causing atmospheric pollution include metal smelting, the chemical and pharmaceutical industries, the production and use of chemicals, and the accumulation and disposal of industrial waste [6][7][8][9][10]. Sources of pollution, such as industrial enterprises and the air around them, are mainly reflected in the emission of air pollutants, sedimentation of particles on the ground, and unreasonable accumulation of industrial solid waste [1,[11][12][13][14]. In general, industrial "three-waste" emissions are the direct cause of regional air pollution.…”

Samples of atmospheric depositions from five types of functional areas in Shijiazhuang, Hebei Province, China, were collected, and the concentrations of six toxic heavy metals (Cd, Cr, Cu, Pb, Ni, and Zn) were measured. Geographic information system, Pb isotope assessment, multivariate statistical analysis (principal component analysis, PCA), the geoaccumulation index (Igeo), potential ecological risk index (PERI), and a health risk assessment model were used to study the degree of pollution, identify sources of pollution, and assess the health risks to children and adults via three pathways (hand–mouth intake, skin contact, and respiration). The results show that the high traffic volume and exhaust gas emissions have led to high concentrations of heavy metals. The Igeo and PERI values of Cd (0.38–2.0 and 108–4531, respectively), indicating the present high pollution level and potential risk, respectively, varied the most. Pb isotope and PCA showed that Pb, Zn, and Cd from atmospheric deposition come from power plants and traffic—Cu is related to traffic, and Ni and Cr come mainly from soil particles (natural source). The health risk assessment showed that heavy metals in atmospheric depositions are at a safe level in the study area.

“…The determination of terrigenous particle provenance, of both eolian or riverine input, in Mediterranean marine sediments has, in general, been based on geochemical and mineralogical data (e.g., Coudé-Gaussen et al, 1987;Foucault and Mélières, 2000;Wehausen and Brumsack, 2000;Caquineau et al, 2002;Weldeab et al, 2002aWeldeab et al, , 2002bWeldeab et al, , 2003Díaz-Hernández et al, 2011;Formentti et al, 2011) as well as on remote sensing methods, analysis of surface dust observations, back-trajectory analysis, and the use of mineral tracers (e.g., Goudie and Middleton, 2001;Laurent et al, 2008). Radiogenic isotopes (Sr, Nd, Pb) are likewise powerful tracers for identifying and characterizing source areas of terrigenous material, which may in turn give us additional information about the provenance and transport mechanisms (e.g., Grousset et al, , 1992Grousset et al, , 1998Revel et al, 1996;Tütken et al, 2002;Grousset and Biscaye, 2005;Jullien et al, 2007;Cole et al, 2009;Box et al, 2011;Meyer et al, 2011;Stumpf et al, 2011;Scheuvens et al, 2013).…”

“…Arid areas contribute a disproportionate amount of both total dust (Marticorena 2014) and Kfs owing to the low soil surface stability and lower rates of chemical weathering respectively. KFF in dust has been measured between 0.18 and 25, which reflects local upwind dust sources (Kandler et al 2009(Kandler et al , 2011Díaz-Hernández et al 2011). On average, however, Kfs contributes c. 3 wt% to the global mineral aerosol budget, and becomes comparatively well mixed in the atmosphere (Atkinson et al 2013).…”

Potassium feldspar present in global mineral aerosol (<5%) plays a disproportionate role in modulating the microphysics of mixed-phase cloud. Via exceptional ice nucleation properties, it is capable of changing cloud properties and behaviour. Here we identify times of substantial and abrupt change in the global availability of potassium feldspar since 600 Ma. Normally, weathering and vegetation cover contribute to low availability, with clay dominating mineral aerosol. Periods of maximum availability are reasoned to follow the emplacement and remobilization of ejecta blankets from major meteorite impact events, before returning to background after some hundreds to thousands of years. We review the 44 largest confirmed craters and evaluate the potassium feldspar content of their target rocks, which range from c. 0 to >30%. By combining crater size and tectonic reconstructions, we are able to provide a quantitative and self-consistent assessment of changes to global potassium feldspar availability. Considerable differences in potassium feldspar availability following meteorite impact events are revealed. Different impact events generated dust containing different amounts of potassium feldspar. Differing levels of influence upon climate are hypothesized, and should now be tested by looking at stratigraphic records of these events to reveal the sensitivity of climate to different dust mineralogy. Supplementary material: Figures showing palaeolatitude determinations using various methods and reconstruction models, and estimates of alkali feldspar abundance and distribution across contemporary continental landmasses for meteorite impact events are
