Recognition and detailed characterization of solid particles emitted from thermal power plants into the environment is highly important due to their potential detrimental effects on human health. Snow cover is used for the identification of anthropogenic emissions in the environment. However, little is known about types, physical and chemical properties of solid airborne particles (SAP) deposited in snow around thermal power plants. The purpose of this study is to quantify and characterize in detail the traceable SAP deposited in snow near fossil fuel thermal power plant in order to identify its emissions into the environment. Applying the scanning electron microscopy-energy dispersive spectroscopy, and X-ray diffraction, mineral and anthropogenic phase groups in SAP deposited in snow near the plant and in fly ash were observed. We identified quartz, albite and mullite as most abundant mineral phases and carbonaceous matter, slag and spherical particles as dominate anthropogenic phases. This is the first study reporting that zircon and anthropogenic sulphide-bearing, metal oxide-bearing, intermetallic compound-bearing and rare-earth element-bearing particles were detected in snow deposits near thermal power plant. The identified mineral and anthropogenic phases can be used as tracers for fossil fuel combustion emissions, especially with regard to their possible effect on human health.
由于热电厂排放到环境中的固体颗粒可能对人类健康产生有害影响,因此对其进行识别和详细表征非常重要。积雪被用于识别环境中的人为排放物。然而,对于热电厂周围雪中沉积的空气中固体颗粒(SAP)的类型、物理和化学性质却知之甚少。本研究的目的是详细量化和表征化石燃料热电厂附近雪中可追踪的SAP,以便识别其向环境中的排放。应用扫描电子显微镜-能量色散光谱和X射线衍射,观察了热电厂附近雪中沉积的SAP以及飞灰中的矿物相和人为相组。我们确定石英、钠长石和莫来石是最丰富的矿物相,而碳质物质、炉渣和球形颗粒是主要的人为相。这是第一项报告在热电厂附近积雪中检测到锆以及含人为硫化物、含金属氧化物、含金属间化合物和含稀土元素颗粒的研究。所识别的矿物相和人为相可作为化石燃料燃烧排放的示踪剂,特别是考虑到它们可能对人类健康产生的影响。
