“…This work follows the findings reported in an earlier paper (Dall'Osto et al 2008), where a discussion on the metallic constituents of particulate matter determined during this study was presented. Specifically, ATOFMS measurements showed six particle classes rich in alkali and trace metals associated with emissions from steelmaking processes.…”

“…Most of these particle types have already been described in the literature (Liu et al 2003;Pastor et al 2003;Dall'Osto and Harrison 2006) and will not be further discussed here. Of the total particles classified, 32% were apportioned to the steel industry: nonmetallic particle types (eight TSI-ATOFMS classes in total) constituted 27% of the particles, while "metal-rich" types contributed 4.5% of the total (Dall'Osto et al 2008). During this field campaign (Dall'Osto et al 2008, this study), the ATOFMS provided information on the mixing state of the aerosols detected.…”

“…This is compensated by quantitative concentrations afforded by the HR-ToF-AMS and other techniques that were applied in the investigation. In summary, while the study of Dall'Osto et al (2008) presented a detailed study of the size distribution and the metal chemical characterization of airborne particles in the vicinity of a large integrated steelworks, this study focuses on particle types with low metal content. Finally, a table summarizing this study and the one of Dall'Osto et al (2008) is presented as concluding remarks.…”

A campaign took place in Wales (UK) in the spring of 2006 to characterize emissions from a major steelworks through atmospheric measurements. At no time during the measurements was the 24-h air quality standard for PM 10 exceeded. However, real-time measurements of single particles by aerosol time-offlight mass spectrometry (ATOFMS) allowed detection of particulate matter from the steelworks, which could be associated with specific emission areas within the works from measurements of wind direction. Three main wind sectors were identified with possible sources of emissions of fine nonmetallic particulate matter (PM < 1 µm). Characterization of the aerosol composition by a high resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS) of the nonrefractory material associated with the specific plumes is also reported, along with results from other real-time techniques. The ATOFMS detected for the first time a unique elemental sulfur-rich particle type, likely to originate from the blast furnaces. AMS results, supported also by laboratory studies, confirm this finding by reporting elevated mass ratios m/z 64/48 and m/z 64/80. Two other novel ATOFMS particulate types were found to be associated with steelworks emissions. One was characterized by nitrogen-containing organic species, aromatic compounds, and high-molecular-weight (MW) polycyclic aromatic hydrocarbons (PAHs) and was associated with the sources in the area of the hot and cold mills. The second was found to be rich in organic carbon internally mixed with elemental carbon, nitrate, sulfate, and PAHs with lower MW. These particle types were likely related to the coke ovens and the basic oxygen steelmaking plant.

Sources and mixing state of summertime background aerosol in the north-western Mediterranean basin

Abstract. An aerosol time-of-flight mass spectrometer (ATOFMS) was employed to provide real-time single particle mixing state and thereby source information for aerosols impacting the western Mediterranean basin during the ChArMEx-ADRIMED and SAF-MED campaigns in summer 2013. The ATOFMS measurements were made at a ground-based remote site on the northern tip of Corsica.Twenty-seven distinct ATOFMS particle classes were identified and subsequently grouped into eight general categories: EC-rich (elemental carbon), K-rich, Na-rich, amines, OC-rich (organic carbon), V-rich, Fe-rich and Carich particles. Mass concentrations were reconstructed for the ATOFMS particle classes and found to be in good agreement with other co-located quantitative measurements (PM 1 , black carbon (BC), organic carbon, sulfate mass and ammonium mass). Total ATOFMS reconstructed mass (PM 2.5 ) accounted for 70-90 % of measured PM 10 mass and was comprised of regionally transported fossil fuel (EC-rich) and biomass burning (K-rich) particles. The accumulation of these transported particles was favoured by repeated and extended periods of air mass stagnation over the western Mediterranean during the sampling campaigns. The single particle mass spectra proved to be valuable source markers, allowing the identification of fossil fuel and biomass burning combustion sources, and was therefore highly complementary to quantitative measurements made by Particle into Liquid Sampler ion chromatography (PILS-IC) and an aerosol chemical speciation monitor (ACSM), which have demonstrated that PM 1 and PM 10 were comprised predominantly of sulfate, ammonium and OC. Good temporal agreement was observed between ATOFMS EC-rich and K-rich particle mass concentrations and combined mass concentrations of BC, sulfate, ammonium and low volatility oxygenated organic aerosol (LV-OOA). This combined information suggests that combustion of fossil fuels and biomass produced primary EC-and OC-containing particles, which then accumulated ammonium, sulfate and alkylamines during regional transport.Three other sources were also identified: local biomass burning, marine and shipping. Local combustion particlesPublished by Copernicus Publications on behalf of the European Geosciences Union. (emitted in Corsica) contributed little to PM 2.5 particle number and mass concentrations but were easily distinguished from regional combustion particles. Marine emissions comprised fresh and aged sea salt: the former was detected mostly during a 5-day event during which it accounted for 50-80 % of sea salt aerosol mass, while the latter was detected throughout the sampling period. Dust was not efficiently detected by the ATOFMS, and support measurements showed that it was mainly in the PM 2.5-10 fraction. Shipping particles, identified using markers for heavy fuel oil combustion, were associated with regional emissions and represented only a small fraction of PM 2.5 particle number and mass concentration at the site.

Many of the significant advances in our understanding of atmospheric particles can be attributed to the application of mass spectrometry. Mass spectrometry provides high sensitivity with fast response time to probe chemically complex particles. This review focuses on recent developments and applications in the field of mass spectrometry of atmospheric aerosols. In Part II of this two-part review, we concentrate on real-time mass spectrometry techniques, which provide high time resolution for insight into brief events and diurnal changes while eliminating the potential artifacts acquired during long-term filter sampling. In particular, real-time mass spectrometry has been shown recently to provide the ability to probe the chemical composition of ambient individual particles <30 nm in diameter to further our understanding of how particles are formed through nucleation in the atmosphere. Further, transportable real-time mass spectrometry techniques are now used frequently on ground-, ship-, and aircraft-based studies around the globe to further our understanding of the spatial distribution of atmospheric aerosols. In addition, coupling aerosol mass spectrometry techniques with other measurements in series has allowed the in situ determination of chemically resolved particle effective density, refractive index, volatility, and cloud activation properties.
