Abstract

Samples of PM10 and PM2.5 were collected from several natural and anthropogenic sources using in-stack cyclone, grab sampling/resuspension chamber and ambient air samplers. The chemical characterization of the samples was achieved containing Al, Ba, Ca, Cd, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Sr, V and Zn using an inductively coupled plasma-optical emission spectrometer (ICP-OES). The elemental fractions (weight percent by mass), standard deviations and uncertainties were reported. The elemental compositions of PM emitted from mineral industries and cement kiln were dominated by terrestrial elements, particularly Ca, whereas the profile of top-soil mainly contained Al and Ca. The profiles of industrial sources were generally typical for related ones; however, significant differences were obtained for some of them. Similarly, the profiles of fuel burning emissions have significant differences compared to profiles obtained all around the world.

摘要

使用烟囱内旋风分离器、抓取采样/再悬浮室和环境空气采样器从多个自然和人为来源采集了PM10和PM2.5样本。使用电感耦合等离子体发射光谱仪(ICP-OES)对样本进行化学表征,分析其中所含的铝(Al)、钡(Ba)、钙(Ca)、镉(Cd)、铬(Cr)、铜(Cu)、铁(Fe)、钾(K)、镁(Mg)、锰(Mn)、钠(Na)、镍(Ni)、铅(Pb)、锶(Sr)、钒(V)和锌(Zn)。报告了元素分数(质量百分比)、标准偏差和不确定度。矿业和水泥窑排放的颗粒物的元素组成以陆地元素为主,尤其是钙,而表层土壤的元素分布主要包含铝和钙。工业源的元素分布通常与相关行业典型情况相符;然而,其中一些存在显著差异。同样,燃料燃烧排放的元素分布与全球范围内获得的分布存在显著差异。
