Determination of Magnesium and Selenium in Leaf Litter

Fall 2004
Abstract:
Concentrations of magnesium and selenium were
determined in the leaf litter of White Oak and Big-Leaf Maple with a JY 2000 ICP
emission spectrometer. The results were fairly consistent across the three sites
studied, with the average magnesium concentration determined to be 2/53±0.6 g/kg
dry weight. Selenium concentrations were below the detection limit for 10 out of
12 samples, and were not quantifiable.
