<br />15 <br />operation that could in turn detrimentally affect herbivores utilizing the <br />vegetation. <br />In addition to the detailed cheiucai analyses discu4sed above, <me <br />crnposite soil sample from location Number Six (control) an Ute Pass taken in <br />1979 was cac~ared with a canposite tailing sample using spark source mass <br />spectranetry. Sales were analyzed by CD`!/Accu Lab in Wheat Ridge, Colorado. <br />This analysis was useful for canparing concentrations of numerous elements in <br />tailing with that in soil to determine whether large differences in <br />concentrations existed. High concentrations of sane potentially toxic <br />elements in tailing might be indicative of elements to monitor in future <br />samples. <br />All remaining samples of the soil and vegetation materials have been <br />stored for possible future use. These samples are available foz any <br />additional analysis should this prove to be desirable. <br />All chemical constituent data were subjected to standard analysis of <br />variance procedures to determine whether significant differences among site or <br />year of sale collection were evident. When significant F-values (p < 0,05) <br />were obtained, Tukey's test was used to separate significant (p < 0.0'5) mean <br />differences. <br />RESULTS AND DISCUSSICSf <br />Elemental Analysis of Soil and Tailing <br />A comparison of elemental concentrations in a native soil fran a~i aspen- <br />fir carmaiity (control) an Ute Pass in 1979 with that of the Hendersoai tailing <br />indicated that 19 ela-wsits were considerably more concentrated in tailing than <br />in soil, whereas 17 elements were considerably more concentrated in soil than <br />
