Routine determination of sulfonylurea, imidazolinone, and sulfonamide herbicides at nanogram-per-liter concentrations by solid-phase extraction and liquid chromatography/mass spectrometry
Autor: Mark R. Burkhardt, Edward T. Furlong, William A. Battaglin, Paul M. Gates, Stephen L. Werner
Publikováno v: Science of The Total Environment. 248:135-146
Sulfonylurea (SU), imidazolinone (IMI), and sulfonamide (SA) herbicides are new classes of low-application-rate herbicides increasingly used by farmers. Some of these herbicides affect both weed and crop species at low dosages and must be carefully u

Determination of Submicrogram-per-Liter Concentrations of Caffeine in Surface Water and Groundwater Samples by Solid-Phase Extraction and Liquid Chromatography
Autor: Stephen L. Werner, Paul P. Soliven, Mark R. Burkhardt, Deborah G Vaught
Publikováno v: Journal of AOAC INTERNATIONAL. 82:161-166
A method for determining submicrogram-per-liter concentrations of caffeine in surface water and groundwater samples has been developed. Caffeine is extracted from a 1 L water sample with a 0.5 g graphitized carbon-based solid-phase cartridge, eluted

Bioaccumulation of pharmaceuticals and other anthropogenic waste indicators in earthworms from agricultural soil amended with biosolid or swine manure
Autor: Edward T. Furlong, Dana W. Kolpin, Steven D. Zaugg, Mark R. Burkhardt, Mark J. Benotti, Joseph P. Bossio, Stephen L. Werner, Chad A. Kinney
Publikováno v: Environmental sciencetechnology. 42(6)
Analysis of earthworms offers potential for assessing the transfer of organic anthropogenic waste indicators (AWIs) derived from land-applied biosolid or manure to biota. Earthworms and soil samples were collected from three Midwest agricultural fiel

Publikováno v: Open-File Report.
Fish exhibiting external lesions, incidences of intersex, and death have recently been observed in the Shenandoah and James River Basins. These basins are characterized by widespread agriculture (intensive in some areas), several major industrial dis
