What Toxic Metals Come out of the Catalytic Converters on Car Mufflers?


Analysis of model Pd- and Pt-containing contaminants in aqueous media using ESI-MS and the fragment partitioning approach (Abstract, Leonid V. Romashov, Gleb D. Rukhovichb and Valentine P. Ananikov, RSC Advances, Institute of Organic Chemistry, Russian Academy of Sciences, Dec. 7, 2015)

Today we review research from Russia into the inadvertent release of toxic metals from catalytic converters (or autocatalyst as it is termed here) which convert exhaust gases such as NOx, CO and other dangerous compounds to CO2, water and nitrogen. However, contact with water leaches the precious metals such as paladium, platinum and rhodium into toxic clusters – how toxic must be evaluated in the future but may put into question the role of the converters.
