“…Mean Rh concentration (17.9 ng/g) in this study compares favourably with those of Bialystok, Poland (19.6 ng/g) 23 and Ioannina, NW Greece (6.1-64.6 ng/g). Mean Pd concentration (79.8 ng/g) is similar to those reported in San Diego USA (38-280 ng/g) 24 , Germany (1-146 ng/g) 25 , Perth, Australia (58.1-440.4 ng/g) 19 , and Goteborg, Sweden (80 ng/g) 26 . Thus PGEs (Pd, Pt and Rh) from the nine sampled sites in Newcastle city centre indicate a strong anthropogenic signal.…”

“…The mean value of Pd is significantly higher than those of Rh and Pt. This is not surprising, as there is a widespread shift in the development of catalytic converter technology away from Pt towards Pd as the main catalytic component 19 . Samples 11, 13 and 19 exhibit the highest concentration of Pd contributing 28.4%, 23.2% and 26.1% respectively, of the total PGE concentration.…”

Introduction of catalytic converter in our automobiles played a vital role in the reduction of harmful emissions such as carbon monoxide, volatile organic compounds and oxides of nitrogen. The three-way catalytic converter which consists of platinum (Pt), palladium (Pd) and rhodium (Rh; Pt-Pd-Rh), while reducing harmful emissions also increases the concentration of platinum group elements (PGEs) into the environment. This situation is due to the deterioration of the surface abrasion of the catalytic converter, thus releasing the PGEs adsorbed in small particles into the environmental compartments of air, soil and water. In this study, the concentration of PGEs in the environment was investigated using road dust collected from the city of Newcastle upon Tyne as a case study. The results obtained using ICP-MS revealed an elevated concentration in PGEs in the road dust in comparison to the lithospheric average. From the study, the average concentration is as follows: platinum = 38.23 ng/g, palladium = 79.8 ng/g and rhodium = 17.56 ng/g. The average concentration of PGEs in the lithosphere is 5.0  10 -6 ng/g for Pt, 1.5  10 -5 ng/g for Pd and 1.0  10 -7 ng/g for Rh.

“…10,11 Ruthenium, Ir, and Os are considered to be present as catalytic components or impurities and are released along with other PGE. While these elements can also trace PGE sources, only limited data have been reported for these elements.…”

Os ratio of this standard was determined to be 0.537 AE 0.022 (95% confidence level; n ¼ 10). These are the first comprehensive PGE and Re concentrations and Os isotopic compositions reported for BCR-723 and provide a well-characterized standard for assessing the data quality of autocatalyst PGE measurements and related research on environmental materials. The method was successfully employed in the determination of PGE and Re concentrations and Os isotopic compositions in urban road dust samples.

“…The lack of direct correlation between Pt levels in road dusts and traffic volume indicates that there is something else to affect Pt levels in road dusts. Among these are driving style and topography (Whiteley and Murray 2003;Ward and Dudding 2004). Although there was no straightforward correlation, it indicates again an evident tendency to increase Pt levels in road dusts along with traffic volume.…”

This study presents the level of platinum in urban environment in and around Seoul, the capital city of Korea. Road dust, roadside soil, and tree bark samples were collected from the sites of various traffic volumes and from control sites in the suburbs. The above samples were analyzed for Pt by ICP-MS and other heavy metals by ICP-OES. Platinum levels in road dusts and roadside soils from Seoul were in the range of 3.8-444 ng/g (av. 115.0 ng/g) and 0.7-221 ng/g (av. 49.7 ng/g), respectively, whereas those in the suburbs were in the range of 2.3-5.2 ng/g (av. 3.9 ng/g) in road dusts and 0.4-5.1 ng/g (av. 2.4 ng/g) in roadside soils. The highest Pt levels in road dusts were found from major roads with high traffic volume. The remarkable difference in average Pt level between heavy traffic roads (av. 132.2 ng/g) and light traffic roads (av. 22.8 ng/g) reflects that an important source of Pt in roadside environment is automobile catalytic converter. High Pt level in road dust was found from the site of erratic stop-start driving condition, for example, 178 ng/g Pt in road dust around a vehicle crossing gate. Platinum level in tree barks ranged from 0.9 to 4.5 ng/g, which indicates the existence of Pt-containing particulate matter in the atmosphere. Road dusts with high Pt level were enriched in traffic-related heavy metals.
