TRACE METALS
 The transition metals and post-transition
metals are common pollutants which
require the use of environmental analyses.
• Transport of the metals occurs by a variety
of mechanisms.
1) Other than Hg most metals have a very low pvap which means that they will deposit in the atmosphere onto aerosol surfaces.  These will dry deposit.
2) Depending on the pH, pE conditions
and the variety of counterions & ligands
present the KSP values will dictate which metals are present in solution as free ions.
