“…Sites exposed to stop/start cycles generally hold a high accumulation factor of PGEs and Pb, but the levels are not only determined by the driving conditions but also by the diurnal variation of the traffic volume. In the city center (site 1) and at the toll station (site 6), higher concentrations were Although, the concentration levels of PGEs were comparable to other large European cities, the Pt/Rh, Pt/Pd, and Pd/Rh ratios observed in the present study were not in agreement with the potential catalytic converter manufacturing ratios derived from elementelement plots Lesniewska et al 2004), used by previous studies to demonstrate that catalytic converter attrition was responsible for elevated abundances of PGEs. The highest ratio was observed for Pt/Pd followed by Pt/Rh and Pd/Rh, which is in agreement with previous reports (Schafer et al 1999), although other trends have also been observed (Ely et al 2001;Whiteley and Murray 2003).…”

The emission of platinum group elements (PGEs) from automobile catalytic converters has led to rapid increases in Pt, Pd, and Rh concentrations in roadside media. This article represents the first systematic study in Greece to assess PGE levels in road dust and roadside soil and their temporal variation on a seasonal basis over a 12-month period. Road dust and roadside soil samples were analyzed by graphite furnace atomic absorption spectrometry following microwave digestion. Concentrations of PGE in all samples were above the average upper crust values and local background levels, with maximum values of 306.4 ng/g Pt, 18.2 ng/g Pd, and 64.6 ng/g Rh in road dust and 225 ng/g Pt, 14.0 ng/g Pd, and 49.5 ng/g Rh in roadside soil. PGE ratios were not consistent with known catalytic converter composition throughout the sampling period reflecting the high emission of Rh from new catalytic converters. Spatial variations were influenced by various factors like driving style, matrix composition, diurnal change in traffic volume, and climatic conditions. With regard to seasonal variations, systematic changes in the temporal distribution of PGE levels were observed and followed a similar pattern between the two matrices. Except PGEs, Pb levels were determined, since it has been a typical indicator of vehicle-derived environmental lead pollution. The data indicate that despite the use of unleaded gasoline, traffic-related sources of Pb that induce levels above the local background have not been eliminated.

A voltammetric method using solid electrode of glassy carbon as a working electrode is describes for determination of platinum in grass samples taken from the vicinity of a motorway. Standard addition was used for quantitative analysis of Pt in 0.05 M H 2 SO 4 . The analyte concentration in plant tissues reached 19.1 AE 1.6 ng g À1 for leaves of samples collected from the least polluted areas, and up to 136 AE 2 ng g À1 for roots of sample taken from the area of heavy roadtraffic.
