ISTC has published two new technical reports. In Yet-to-emerge contaminants in the Great Lakes region: Analytical method development and measurement of concentrations in a Great Lakes fish, researchers developed a screening method to extract and analyze a group of ten persistent, bioaccumulative, and toxic (PBT) substances and applied those methods to measure the concentrations of those compounds in lake trout collected from Lake Michigan.
In Occurrence and Fate of the Herbicide Glyphosate in Tile Drainage and Receiving Rivers in East Central Illinois, researchers developed an analytical method to monitor the occurrence of the herbicide glyphosate and its metabolite, aminomethylphosphonic acid (AMPA), in tile drain water and receiving river water collected in east central Illinois agricultural lands. The developed method was then used to monitor glyphosate and AMPA in tile drainage and their receiving watersheds (e.g., the Spoon River and Salt Fork). Additional data collected during this study are available in Woodword, et al (2019). “Fate and transport of nitrapyrin in agroecosystems: Occurrence in agricultural soils, subsurface drains, and receiving streams in the Midwestern US.” Science of The Total Environment 650(2), 2830-2841. https://doi.org/10.1016/j.scitotenv.2018.09.387.
