Abstract
Concentrations of selenium, fluorine, and arsenic in 912, 911, and 910 samples, respectively, of soils and other regoliths from sites approximately 50 miles (80 km) apart throughout the United States are represented on maps by symbols showing five ranges of values. Histograms of the concentrations of these elements are also given. The geometric-mean concentrations (ppm) in the samples, grouped by area, are as follows:
Selenium-- Entire United States, 0.31; Western United States, 0.25; and Eastern United States, 0.39.
Fluorine-- Entire United States, 180; Western United States, 250; and Eastern United States, 115.
Arsenic-- Entire United States, 5.8; Western United States, 6.1; and Eastern United States, 5.4.
