Statistical Analysis and Areal Trends of Background Concentrations of Metals inSoils of Clark County, Washington

摘要

This report presents data on the magnitude and variability of backgroundconcentrations of metals in ssoils in Clark County. This information was used to (1) compare the results of the different laboratory methods used; (2) characterize individual sources of variance (for example, the variability of metals concentrations in soils as a fucntional of depth); (3) examine the relations among different metals and between metals concentrations and other soil properties (for example, the content of copper versus the content of organic carbon in the soil); and (4) determine if different soil types, soil associations, or some other grouping of samples were characterized by particular assemblages of metals. The report presents, in tabular form, all the data collected in this study.
