A new project is looking at PGE pollution
in the environment.
These elements, particularly Pt, Rh, and Pd are continually being
into the environment via catalytic converters. While their use in
automobiles cuts down greenhouse gas emissions, the effects of the PGEs
on the environment are unknown. What is known is that Pt is a
carcinogenic material if complexed with organic molecules. What
not known is whether Pt and Rh make it into the food chain from this
We have shown that Pt and Rh are present in roadside dirt around South
Bend. We are now expanding this study to look at vegetation as
