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

在安第斯山脉的市区，确定了活火山的排放对纳米颗粒和超细道路粉尘组成的影响。尽管许多城市都靠近活跃的火山，但很少有研究评估它们对道路灰尘成分的影响。非废气排放（例如道路灰尘，刹车磨损，轮胎磨损）严重影响了城市地区的空气质量，但是，火山等自然资源也会影响颗粒物的化学成分。在这项研究中，来自火山排放的元素，例如Si> Al> Fe> Ca> K> Mg和SiAl和K被鉴定为复杂水合物。类似地，在纳米颗粒和超细材料中观察到As，Hg，Cd，Pb，As，H，Cd，Pb，V和salammoniac。除火山岩示踪剂萨拉莫尼亚克外，还按石英>莫来石>方解石>高岭石>伊利石>针铁矿>磁铁矿>锆石>独居石的顺序检测矿物成分。前述分析反映了进行更多有关道路灰尘中火山排放影响的研究以保护人类健康的重要性。在城市中，道路灰尘负荷（RD ₁₀）在0.8至26.8 mg m ^-2之间。
