Analysis of pesticides in surface water and sediment from Yolo Bypass, California, 2004-2005 Analysis of pesticides in surface water and sediment from Yolo Bypass, California, 2004-2005
Inputs to the Yolo Bypass are potential sources of pesticides that could impact critical life stages of native fish. To assess the direct inputs during inundation, pesticide concentrations were analyzed in water, in suspended and bed-sediment samples collected from six source watersheds to the Yolo Bypass, and from three sites within the Bypass in 2004 and 2005. Water samples were...

Concentrations of organic contaminants detected during managed flow conditions, San Joaquin River and Old River, California, 2001 Concentrations of organic contaminants detected during managed flow conditions, San Joaquin River and Old River, California, 2001
Concentrations of organic contaminants were determined in water samples collected at six surface-water sites located along the San Joaquin and Old Rivers during April through June 2001. Water samples were collected, coincident with salmon smolt caging studies conducted by researchers from the Bodega Marine Laboratory at the University of California at Davis to characterize exposure of...

Glyphosate, other herbicides, and transformation products in Midwestern streams, 2002 Glyphosate, other herbicides, and transformation products in Midwestern streams, 2002
The use of glyphosate has increased rapidly, and there is limited understanding of its environmental fate. The objective of this study was to document the occurrence of glyphosate and the transformation product aminomethylphosphonic acid (AMPA) in Midwestern streams and to compare their occurrence with that of more commonly measured herbicides such as acetochlor, atrazine, and...

Changes in Rice Pesticide Use and Surface Water Concentrations in the Sacramento River Watershed, California Changes in Rice Pesticide Use and Surface Water Concentrations in the Sacramento River Watershed, California
Pesticides applied to rice fields in California are transported into the Sacramento River watershed by the release of rice field water. Despite monitoring and mitigation programs, concentrations of two rice pesticides, molinate and thiobencarb, continue to exceed the surface-water concentration performance goals established by the Central Valley Regional Water Quality Control Board...

Dissolved pesticide and organic carbon concentrations detected in surface waters, northern Central Valley, California, 2001-2002 Dissolved pesticide and organic carbon concentrations detected in surface waters, northern Central Valley, California, 2001-2002
Field and laboratory studies were conducted to determine the effects of pesticide mixtures on Chinook salmon under various environmental conditions in surface waters of the northern Central Valley of California. This project was a collaborative effort between the U.S. Geological Survey (USGS) and the University of California. The project focused on understanding the environmental factors...

Genotoxicity in native fish associated with agricultural runoff events Genotoxicity in native fish associated with agricultural runoff events
The primary objective of the present study was to test whether agricultural chemical runoff was associated with in-stream genotoxicity in native fish. Using Sacramento sucker (Catostomus occidentalis), we combined field-caging experiments in an agriculturally dominated watershed with controlled laboratory exposures to field-collected water samples, and we coupled genotoxicity biomarker
