Environmental Chemistry Laboratory — Columbia, Missouri

About the Laboratory

The Environmental Chemistry Laboratory at the Columbia Environmental Research Center, Missouri, develops and applies innovative methods of sampling and analysis to answer critical questions about the occurrence, distribution, fate and transport, and biological exposure of chemical in all environmental matrices (water, air, tissues, sediments, and others).
