The input of Cadmium, Zinc, Copper, Lead and Nickel was studied at remote areas in Idaho, Utah, Colorado and Wyoming. Concentrations of metals in dustfall collected over two separate time intervals were compared to those from surface soil at each of the sampling sites. Although significant correlation was found among the various metals in soil, there was no significant relationship noted between levels in dustfall and in corresponding soil samples at the individual locations. A general randomness was observed in heavy metal burdens throughout the sampling network, yet, a significant equivalence existed in deposition rates (μg/m2/day) of total dustfall, Cd, Cu and Pb at the individual sites when compared using a paired t-test. Likewise, equivalence was found in concentrations of Cd and Pb suggesting that local, rather than regionwide, climatic factors may be responsible for the variation in metal levels in atmospheric fallout. |
