Application of N and C isotopic ratios bulk analysis in particulate matter (PM) for source allocation
The carbon and nitrogen isotopic compositions of aerosol particles collected in the city Krakow were measured as part of the JRC-IES Krakow project. Particulate matter samples were collected during two episodes of thermal inversion (14.01-2.3.2006) and at four different air monitoring stations in Krakow (Agri: urban background site, Indu: industrial site at Nowa Huta, Poli: domestic coal heating district, Traffic: traffic site), from the Zakopane sub-urban mountain site (Zaco), dominated by domestic coal heating, and from four apartments (indoor and outdoor). A total of 86 samples (including 19 source samples) were measured by Isotope Ratio Mass Spectrometry (IRMS). The elemental composition (total C and N fraction) was obtained simultaneously with the isotopic measurement. The combination of nitrogen and carbon isotopic data shows that the PM sources can be clearly distinguished. The results for samples from different locations show clear grouping of related samples and allow of probable source allocation, but are also indicating the possibility of (a) source(s) which was not identified and sampled within this project. This is confirmed in the combination of elemental and isotopic analysis of nitrogen, in which (a) source(s) with a high 15N/14N seem(s) to be missing. From the combined elemental analysis and isotopic carbon results there is a systematic grouping of the sample results.
