Volcanic emissions and atmospheric pollution: A study of nanoparticles

The influence of emissions an active volcano on the composition nanoparticles and ultrafine road dust was identified in urban area Andes. Although many cities are close to volcanoes, few studies have evaluated their composition. Air quality areas is significantly affected by non-exhaust (e.g. dust, brake wear, tire wear), however, natural sources such as volcanoes also impact chemical particles. In this study, elements from volcanic Si > Al Fe Ca K Mg, SiAl with were complex hydrates. Similarly, As, Hg, Cd, Pb, H, V, salammoniac observed material. Mineral detected order quartz> mullite> calcite> kaolinite> illite> goethite> magnetite> zircon> monazite, addition salammoniac, a tracer sources. foregoing analysis reflects importance carrying out more relating protect human health. load (RD10) ranged between 0.8 26.8 mg m−2 city.
