Quantitative Determination of Selenium and Mercury, and an ICP-MS Semi-Quantatitive Scan of Other Elements in Samples of Eagle Tissues Collected from the Pacific Northwest, Summer 2011.

摘要

A group of 182 eagle tissue samples was received by the inorganic section of the Columbia Environmental Research Center (CERC) on August 18, 2011, consisting of liver (number (n)=26), kidney(n=25), brain (n=23), talon (n=25), feather (n=25), femur (n=25), humerus (n=25), and stomach contents (n=8). The samples originated from frozen eagle carcasses collected from the Pacific Northwest. The sample group was assigned Batch 1936 and CERC identifications 55117-55297, and Batch 2052 for 57302. This sample collection was part of a study to document the occurrence of metal and metalloid contaminants in tissues of eagle carcasses. These tissues were to be quantitatively analyzed for concentrations of selenium (Se) and mercury (Hg), and for other elements by semi-quantitative scan (TotalQuant) with an inductively coupled plasma-mass spectrometer (ICP-MS).
