Vehicle exhaust and other sources of air pollution spew out metallic fragments that then adhere to nearby tree leaves, said study leader Bernie Housen, a geophysicist at Western Washington University in Bellingham, Washington...Housen's study revealed that leaves plucked from trees along regular bus routes were up to ten times more magnetic than those on quieter streets.
