“…Due to traffic density and industrial organizations large cities are obvious locations where the potential hazardous effects of PGEs might be observed [4]. A number of articles has been published concerning PGEs and their increasing concentrations in different environmental media such as: air and airborne particulate matter [5][6], soil [7], road dust [8][9][10], vegetation [11], organisms [12][13], and sewage sludge [14]. Some PGE elements and their complex salts such as Pd-, Rh-and Pt-chlorides, have been reported as potential risks, not only to the environment [15][16], but also to the human health, causing tumor, asthma, rhinoconjuctivitis and other serious health problems [16][17].…”

In this study, rhodium, palladium, platinum, gold and cerium were determined by ICP-MS after trace-matrix separation in roadside dusts and soil samples along different motorways in Ankara and Bursa, and in soil samples taken from industrial locations in Nilüfer, Bursa. The clear presence of Pd and Rh was determined at different traffic locations. Platinum remained below the method's quantification limit for most of the samples. Results showed that both cities showed relatively high concentrations of; Rh and Pt in tunnels and downtowns, Pd in tunnels, bus stations and crossroads, and Au in downtowns. Consistent with the daily road traffic, relatively high concentrations of Rh, Pd and Pt were determined for Ankara. Based on the limited data available for Pt, Pt:Pd ratios varied between 0.04 and 0.25, and Pt:Rh ratios varied between 0.59 and 2.1. Measurements at the industrial location showed an average Rh and Pd concentration of 11 and 359 µg/kg, respectively. On the other hand, Au concentrations remained below the method's quantification limit except for one sampling location. The average Ce concentration was determined as 23 mg/kg. Platinum remained below the method's quantification limit for all industrial sampling locations. Overall, high average Rh and Pt concentrations were determined at the traffic sites, while higher average Pd concentration was determined at the industrial locations. Cerium remained consistently below the earth's crustal levels, which infers that no anthropogenic source can be attributed to Ce.
