Dear Isogeochemists...

I'm looking for relevant experiences discriminating
the origin of lead and chromium in airbone dust
(PM10).  Two main possible sources of lead are
identified: the first lead from gasoline due to heavy
traffic (still present in LDCs) and the second
emissions from medium size smelters.  Does anybody has
experience or publications regarding to using isotope
signals as a tool to identify, for sure, sources of
metals such as lead and chromium in airbone dust?

Many thanks for any input,

Alfredo Torrico
