TB119: Selected Relationships for Trace Metals in Maine Low Elevation Spruce-Fir Forest FloorsTechnical Bulletins
DescriptionResults from the analysis of trace metals in the forest floor from three study areas northern Maine commercial spruce-fir stands showed significant, positive correlations were frequently evident between ash-free concentrations of Individual pairs of trace metals. Only Pb concentrations at one location were found to vary significantly among soil drainage classes. Overall, ash-free trace metal concentrations were less than what has been found at sites receiving high loadings of atmospheric deposition in the Northeast. Few historical data are available to adequately determine if Maine forest floor trace metal concentrations are greater than the natural levels expected in commercial forests, but it appears possible that current concentrations reflect contributions from the atmosphere above background conditions.
