Description:   An investigation into the use of the bark from several North American species of trees as biomonitors of particulate deposition from smelters was performed.  Metals tested for were copper, nickel, iron, arsenic, cobalt, and lead.  The trend discovered was that the closer the trees were to the source, the higher the metal conmcentrations found.  The side of the tree facing the source had higher concentrations than the face opposite.  Wind-borne metal contaminated ground soils were observed to have an influence on the concentrations of metals in the bark samples. Meshbag experiments were also performed and the results showed that mossbags were more sensitive biomonitors then lichenbags, and lichenbags were more sensitive than barkbags.
