XRF_samples_Palmyra_Atoll_2008_and_2010

Soils and organismal tissue from known and potential sources of contamination at Palmyra Atoll were measured for concentrations of 13 elements using a hand-held X-Ray Flourometer (XRF). Measured elements include; Lead (PB), Arsenic (As), Cobalt (Co), Cromium (Cr), Copper (Cu), Antimony (Sb), Iron (Fe), Titanium (Ti), Zinc (Zn), Nickel (Ni), Manganese (Mn), Sulphur (S) and Phosphorous (P). Concentrations of other elements were excluded because they were below the limit of detection or were sporadically detected; these include Tin (Sn), Cadmium (Cd), Silver (Ag), Strontium (Sr), Ruthenium (Rb), Selenium (Se), Mercury (Hg), Vanadium (V), Scantium (Sc), Calcium (Ca), Potassium (K), and Chlorine (Cl).
Attributes for each sample location include an indication of what was being sampled (for example, a waste pile or building), purported building numbers identified from a 1944 U.S. Navy map of facilities, what function the building served, and whether the site is part of areas excluded from USFWS ownership. The matrix (for example, sand, soil or organism) is indicated with an estimate of the area from which the sampled material was collected or that it is supposed to represent. Paths with functional hyperlinks to photographs of sample locations are provided.
