Fonseca AS, Talbot N, Schwarz J, et al., 2016, Intercomparison of four different cascade impactors for fine and ultrafine particle sampling in two European locations
<jats:p>Abstract. Due to the need to better characterise the ultrafine particles fraction and related personal exposure, several impactors have been developed to enable the collection of ultrafine particles (<100 nm). However, to the authors’ kno wledge there have been no field campaigns to-date intercomparing impactor collection of ultrafine particles. The purpose of this study was two-fold: 1) to assess the performance of a number of conventional and nano-range cascade impactors with regard to the particle mass size distribution under different environmental conditions and aerosol loads and types, and 2) to characterise aerosol size distributions including ultrafine particles using impactors in 2 European locations. The impactors used were: (i) Berner low-pressure impactor (BLPI; 26 nm - 13.5 μm), (ii) nano-Berner low-pressure impactor (nano-BLPI; 11 nm - 1.95 μm) and (iii) Nano-microorifice uniform deposit impactor (nano-Moudi; 10 nm-18 μm), and (iv) Personal cascade impactor Sioutas (PCIS; <250 nm - 10 μm). Taking the BLPI as an internal reference, the best agreement regarding mass size distributions was obtained with the nano-BLPI, independently of the aerosol load and aerosol chemical composition. The nano-Moudi showed a good agreement for part icle sizes >320 nm, whereas for particle diameters <320 nm this instrument recorded larger mass concentrations in outdoor air than the internal reference. This difference could be due to particle bounce, to the dissociation of semi volatiles in the coarser stages and/or to particle shrinkage during transport through the impactor due to higher temperature inside this impactor. Further research is needed to understand this behaviour. With regard to the PCIS, their size-resolved mass concentrations were compar able with other impactors for PM1, PM2 and PM10, but the cut-off at 250 nm did not seem to be consistent with that of the internal reference.

Vu VT, Lee BK, Ny MT, et al., 2010, A study on characteristics of organic carbon and polycyclic aromatic hydrocarbons (PAHs) in PM<inf>10</inf>at the residential and industrial areas in Ulsan of Korea, Pages: 263-266
Airborne PMIO has been collected on quartz microfiber filter using a high volume sampler at the urban residential and industrial areas of Ulsan in Korea during June to September 2009. Mean concentrations of PM10 ranged from 16.8 to 54.6 μg/m3 in the residential area and from 24.8 to 89.9 μg/m3 in the industrial area. Organic compounds of PM 10 deposited on quartz microfiber filter were identified by a thermal/optical carbon aerosol analyzer (Sunset Laboratory, Forest Grove) operating on the NIOSH (National Institute of Occupational Safety and Health) Method 5040. Results showed the average concentration of organic carbon in PM10 was 8.1 μg/m3 in the industrial area and approximately 2 times as higher as that in the residential area. 16 priority PAHs listed by US-EPA were extracted in a mixture solution of dichloromethane and n-hexan (1:1, v/v) using an ultrasonic bath and analyzed by high performance liquid chromatography system with ultra-violet detector (HPLC-UVD). The concentrations of total PAHs ranged from 11.1 to 33.7 ng/m3, with an average of 21.49 ng/m3. Flouranthene, pyrene, benzo[k]flouranthene and dibenzo[a,h]athracene were identified as the dominant PAH compounds. Based on PAH diagnostic ratio, the main sources of PAHs in PM10 included oil combustion, diesel emissions and gasoline vehicular emissions. ©2010 IEEE.
