Quantitative Analysis of Water and Biological Samples for Determination of Haleogenated Organics in the Upper Trinity River, Texas : Final Technical Report (open access)

Quantitative Analysis of Water and Biological Samples for Determination of Haleogenated Organics in the Upper Trinity River, Texas : Final Technical Report

This study had three objectives: 1) to develop a method for the quantitative determination of total organic bound chlorine in water and biological samples using Source-Excited X-Ray Fluorescence, 2) to provide training in the use of analytical techniques for students from different disciplines, and 3) to use an interdisciplinary approach involving students of biology, chemistry, and physics to investigate a complex environmental problem. Only the first objective is treated in detail in this volume.
