Organics Division

 

The Organics Division identifies and quantifies trace organic compounds in water, soil, sediment, and tissue at the part-per-billion (ppb) level using EPA, NOAA, and Center developed methods. CESE’s most recent instrument acquisition is a Waters Ultra Performance Liquid Chromatograph with a Tandem Mass Spectrometer (UPLC/MS/MS).

Recent projects supported by the Organics Division include:

  • Determination of concentrations of polycyclic aromatic hydrocarbons (PAHs) and their metabolites blood, sea turtle eggs, and fish in support of the Deepwater Horizon Oil Spill National Resource Damage Assessment.
  • Detection and quantitation of bio-active compounds including furanocoumarins in food and humans, environmental estrogens, and cyanotoxins and their analogs.
  • Developing novel analytical methods supporting rapid responses to emerging threats on commercial shellfisheries.

Some of our clients and collaborators include:

  • U.S. Environmental Protection Agency
  • U.S. Geological Survey
  • Minnesota Department of Natural Resources
  • Clemson University
