Sources of variation in mineral composition of selected plants inhabiting a floodplain at the Savannah River Plant
- Univ. of California, Los Angeles
Using optical emission spectrometry, we analyzed, in triplicate, 56 leaf samples, representing nine plant species from a Savannah River Plant flood plain (partially swampy), for 19 mineral elements. Each sample for trees represented a single tree. Unless the concentration of an element was very low, most of the variation for a given plant species was between samples. The analytical coefficient of variation (CV) was less than 10 percent for the mean of all elements for some species, and the analytical CV differences from species to species were statistically significant. The total CV also varied from element to element within species and was independent of analytical CV. Collection of each sample from a different plant (the trees) resulted in a higher CV. Barium concentrations in leaves were consistently higher than those of strontium in contrast to samples from western plants. All samples were high (500 to 3000 ..mu..g/g) in manganese, typical for podzol soils under acidic and reducing conditions. Species differences were noted for nearly every element. A somewhat elevated concentration of cobalt was found in the leaves of one species. Molybdenum was above the detection limit for only one plant species.
