Screening of platinum group metals from automobile catalysts in soils of Ostrava City

摘要

Automobile catalysts are sources of platinum group metals (PGM) emissions into theenvironment. Since their introduction, the increase of PGM concentrations in differentenvironmental matrices has been observed. This, together with the information abouttoxicity of Pt, Pd and Rh, raises concerns about possible health risks. To obtain input dataon potential exposure to PGM, soil sampling methodology was developed and screeningof PGM in soils was provided in the city of Ostrava at locations with different trafficload, including sites with potential exposure of children. The screening indicates that inimmediate proximity to high traffic, increased Pt, Pd and Rh concentrations are observed.
