一系列的碳纳米颗粒，团聚体和矿物相已被确定在燃烧煤废物堆材料从葡萄牙的Douro煤田，作为确定其潜在的环境和人类健康的影响的基础。这些材料的易碎性和细粒度需要新的表征方法，包括能量色散X射线光谱法（EDS），场发射扫描电子显微镜（FE-SEM）和高分辨率透射电子显微镜（HR-TEM）技术。纳米矿物和相关超细颗粒的化学组成及其与形态的可能相关性已在人类健康暴露的背景下以及与燃煤环境中此类成分的管理相关的情况下进行了评估。
A range of carbon nanoparticles, agglomerates and mineral phases have been identified in burning coal waste pile materials from the Douro Coalfield of Portugal, as a basis for identifying their potential environmental and human health impacts. The fragile nature and fine particle size of these materials required novel characterization methods, including energy-dispersive X-ray spectrometry (EDS), field-emission scanning electron microscope (FE-SEM), and high-resolution transmission electron microscopy (HR-TEM) techniques. The chemical composition and possible correlations with morphology of the nanominerals and associated ultra-fine particles have been evaluated in the context of human health exposure, as well as in relation to management of such components in coal-fire environments.
