“…Operation of the SEAS-III instrument, subsequent analysis of samples, and data QA/QC is discussed by Pancras and Landis. 25 Briefly, the SEAS-III was configured with a PM 2.5 cyclone inlet and sampled at a flow rate of 92 l min −1 . Direct steam injection is used to nucleate aerosols that are subsequently collected by direct impingement.…”

A new source-type identification method, Reduction and Species Clustering Using Episodes (ReSCUE), was developed to exploit the temporal synchronicity typically observed between ambient species in high time resolution fine particulate matter (PM2.5) data to form clusters that vary together. High time-resolution (30 min) PM2.5 sampling was conducted for a month during the summer of 2006 in Steubenville, OH, an EPA designated nonattainment area for the U.S. National Ambient Air Quality Standards (NAAQS). When the data were evaluated, the species clusters from ReSCUE matched extremely well with the source types identified by EPA Unmix demonstrating that ReSCUE is a valuable tool in identifying source types. Results from EPA Unmix show that contributions to PM2.5 are mostly from iron/steel manufacturing (36% ± 9%), crustal matter (33% ± 11%), and coal combustion (11% ± 19%). More importantly, ReSCUE was useful in (i) providing objective data driven guidance for the number of source factors and key fitting species for EPA Unmix, and (ii) detecting tenuous associations between some species and source types in the results derived by EPA Unmix.

“…Their study demonstrated the feasibility of analysing lter tape deposits for source attribution studies, especially for short duration fugitive dust events. Pancras and Landis, 30 building on previous work, 31 evaluated the performance of their semi-continuous elements-in-aerosol (PM 2.5 ) sampler (SEAS-III). The system was designed to sample particles continuously and to deposit them, at 30 minute time intervals, into vials containing water.…”

“…10 mm for quartz from several well characterised BIFs. The d 18 O and d 30 Si values of +7.9& to +27.5& and À3.7& to +1.2&, respectively, provided information on the different sources of Si during the formation of the BIF quartz. The ion microprobe was the technique of choice for providing high precision measurements of oxygen isotope ratios in tiny extraterrestrial particles <100 mm in diameter.…”

This article summarizes the collection methods and analytical approaches used for the analysis of time‐integrated samples (i.e. samples collected over a period of time and returned to the laboratory for analysis) and continuous methods (i.e. in‐field measurements) for the measurement of airborne particles. The collection method needs to be considered an integral part of the quantification process since how samples are collected can impact whether the results represent what is in the air or have been modified. Thus, the primary focus of this article is on measurement process, collection and analysis, with only a short description of the motivation for these measurements.
