BASE-LINE ELEMENT CONCENTRATIONS IN SOILS AND PLANTS, BULL ISLAND, CAPE-ROMAIN-NATIONAL-WILDLIFE-REFUGE, SOUTH-CAROLINA, USA

Baseline element concentrations are given for Spanish moss (Tillandsia usneoides), loblolly pine (Pinus taeda), and associated soils. Baseli ne and variability data for ash, Al, Ba, C, Ca, Cd, Ce, Co, Cr, Cu, Fe , K, La, Li, Mg, Mn, Na, Nb, Nd, Ni, P, Pb, S, Sc, Sr, Th, Ti, V, Y, a nd Zn are reported; however, not all variables are reported for all me dia because, in some media, certain elements were below the analytical detection limit. Spatial variation in element concentration among and within 0.5 km grid cells are given for each of the media. In general, only a few elements in Spanish moss showed statistically significant landscape patterns, whereas several elements in loblolly pine and in s oils exhibited differences among sampling grids. Significant differenc es in the concentration of three elements in Spanish moss and eight el ements (including total S) in loblolly pine were observed between two sampling dates (November and June); however, the absolute amount of th ese differences was small. Except for perhaps Ni and Pb concentrations in Spanish moss, element levels in all sample media exhibited ranges that indicate natural rather than anthropogenic additions of trace ele ments.
