| Description | Manchester Environmental Laboratory developed the capability for Quadrupole Time of Flight (QTOF) analysis through gas chromatography-mass spectrometry (GC-MS) in 2018. Ecology’s Toxic Studies Unit is interested in using this opportunity to (1) assess the potential uses and efficacy of QTOF for future fish tissue toxics screening applications and (2) screen archived fish tissue to better understand the toxics burden of fish above and beyond our current standard practice of analyzing for target analytes. Three sets of archived tissue will be analyzed using QTOF for this project. They include individual samples of white sturgeon collected in the Lower Columbia River in summer 2017, composited finfish species collected in central Lake Washington in summer 2018, and composited finfish species collected in the Lower Cowlitz River in summer 2016. Laboratory analysis is expected to yield a list of tentatively identified compounds, which will be compared to known sample concentrations of the original sample or to regional values. |
