- •
Leaching of PGEs from old and new diesel and gasoline catalysts is pH-dependent.
- •
Highest leaching of PGEs starts under acidic conditions.
- •
Palladium is highly mobile due to the formation of uncharged species.
- •
Higher release of PGEs may occur when catalysts are deposited in acidic soils.
