In an effort to describe past and present air pollutant emissions in the Butte area we employed biomonitoring and dendrochronological techniques. Pine needle, bark, and core samples were collected from trees adjacent to the superfund sites. These samples were digested and analyzed using inductively coupled plasma mass spectrometry (ICPMS). The goal of this analysis is to quantitatively determine the levels of heavy metals over the last century and if this data can be...
