“…This is a very unfavourable situation for Radom inhabitants, as it increases health risk connected with inhalation hazard. The concentrations of chromium in PM10 and PM2.5 are comparable to those quoted by other authors for urban areas [19][20][21][22]24].…”

Abstract. This paper presents seasonal variations in the occurrence of chromium in urban particulate matter (PM). Radom is an interesting area for this type of research due to its typical antiquated heating infrastructure. PM samples of two particulate fractions PM2.5 (particulates ≤ 2.5 μm) and PM10 (particulates ≤ 10 μm) were collected using a Copley cascade impactor Hi-Flow MOUDI Model 130. Chromium was determined in the samples using the GF-AAS technique. The concentration of chromium in PM2.5 was in the range of 0.38 to 3.2 ng/m 3 , whereas in PM10 it ranged from 0.43 to 4.1 ng/m 3 .

“…Similar results were found in several previous studies (Huegline et al, 2005;Sánchez de la Campa et al, 2009). An opposite result, OC/EC ratio of PM 2.5 was lower than that of PM 10 , was found by Puxbaum et al (2004). Conclusively, the pollution sources of different cities many cause different results.…”

The SURFER model is seldom used in combination with the CMB model to look for PM 10 hot spots and estimate the contribution of various sources, and this is the aim of the current study. In addition, the hot spots of ambient particulate matter (PM) and their physicochemical characteristics in a highly polluted zone in southern Taiwan were further investigated and compared. The experimental results show that PM 10 concentration in the fall was higher than in spring and summer. Moreover, northern monsoons transported suspended particles from the upwind emission sources to the sampling sites, causing an increase in secondary aerosols such as sulfate and nitrate. The contribution of secondary aerosols in rural areas such as Dai-liao and Chao-zhou (32.1% and 29.9%) and suburban areas like Ren-wu and Lin-yuan (28.7% and 29.0%) were higher than those in urban areas such as Hsiao-kang (20.3%). The higher Fe concentration in Hsiao-kang was attributed to PM emission from steel factories (6.9-7.8%). In this study, the organic carbon/elemental carbon (OC/EC) in PM 2.5 and PM 10 for the five sites were all in the order of Hsiao-kang > Ren-wu > Lin-yuan > Chao-zhou > Da-liao. In fall, farm burns are very common in both Dai-liao and Chao-zhou, and this source contributed approximately 7.3% and 6.3%, respectively, to these results. The seasonal variation of the contribution from vehicle exhausts to PM 10 (13.9-27.5%) at Hsiao-kang was always higher than those at other sites, especially in the fall. The results could provide important information for cost-effective control strategies to improve ambient air quality in hot spot areas.

“…Iron is a common constituent in combustion particles as well as in ambient aerosols (Puxbaum et al 2004;Wang et al 2003). For example, ratios of Cr:Fe in ambient particulate matter collected in and around Vienna range from 1:2 to 1:10 in urban and rural settings respectively, depending on the types of industry in the area (Puxbaum et al 2004). The Cr:Fe ratios in our samples, which were determined by ICP-MS, were between 1:2 to 1:3, with a typical iron concentration of 190-460 µg per filter.…”

While atmospheric particles can have adverse health effects, the reasons for this toxicity are largely unclear. One possible reason is that the particles can contain toxic metals such as chromium. Chromium exists in the environment in two major oxidation states: III, which is an essential nutrient, and VI, which is highly toxic and carcinogenic. Currently little is known about the speciation of chromium in airborne particles or how this speciation is altered by atmospheric reactions. To investigate the potential impacts of atmospheric aging on the speciation and toxicity of chromiumcontaining particles, we collected chromium and chromium-iron combustion ultrafine particles on Teflon filters and exposed the particles to a combination of light, ozone, water vapor, and, in We thank Dr. Matthew Newville of the GSECARS at the Advanced Photon Source (APS), Argonne National Laboratory, for his assistance. The majority to the X-ray data presented above were collected at GeoSoilEnviroCARS (Sector 13), which is supported by the National Science Foundation-Earth Sciences (EAR-0217473), Department of Energy-Geosciences (DE-FG02-94ER14466) and the State of Illinois. Use of the APS was supported by the U.S. Department of Energy under Contract No. W-31-109-Eng-38. We would also like to thank Dr. Matthew Marcus of beamline 10.3.2 of the Advanced Light Source (Lawrence Berkeley National Laboratory), which is supported by the US Department of Energy (DE-AC02-05CH11231). Portions of this research were also carried out at the Stanford Synchrotron Radiation Laboratory, operated by Stanford University on behalf of the U.S. Department of Energy. Finally, we thank David Paige (Paige Instruments) for constructing the ozone generator, John Newberg and Mike JimenezCruz for building the ozone dilution and delivery system, and Michelle Gras of the UC Davis Interdisciplinary Center for Plasma Mass Spectrometry for conducting the ICP-MS analyses.

After the aging process, the aged and not-aged samples were analyzed for Cr oxidation state using X-ray Absorption Near Edge Spectroscopy (XANES). We found that the aging process reduced Cr(VI) by as much as 20% in chromium particles that had high initial Cr(VI)/Cr(total) ratios. This reduction of Cr(VI) to Cr(III) appears to be due to reactions primarily with light and hydroperoxyl radical (HO 2 ) in the...
