OGRL Algal Toxins Methods of Analysis
Algal toxins are a group of toxic compounds produced by a range of photosynthetic freshwater and marine plankton. These toxins have the ability to cause sickness in animals and humans and in severe cases lead to death. OGRL has the ability to evaluate and conduct occurrence, fate, transport, effects, and treatability studies methods.
Glyphosate, AMPA, and Glufosinate Method of Analysis: OGRL LCGY
Glyphosate and glufosinate are herbicides used for weed and vegetation control. AMPA, aminomethylphosphonic acid, is a degradation product of glyphosate. Since the introduction of glyphosate resistant (round-up ready) corn and soybeans glyphosate has become the most widely used herbicide in the world.
Antibiotic Methods of Analysis: OGRL LCAB
Antibiotics are used for human health and livestock management and health. The increase of antibiotic resistant infections has resulted in concern that sub-therapeutic use of antibiotics for weight gain in livestock and the release of low levels of antibiotics into surface and groundwater from urban and agricultural sources may be contributing to this problem.
Parents and Degradation Products of Analysis: OGRL LCEA
Triazines and phenylureas are commonly used herbicides for controlling weeds in row crops. These herbicides and their degradation products have been found in samples collected from surface water, groundwater, and precipitation throughout the United States. Atrazine until recently was the most widely applied herbicide in the U.S. and is still a widely applied preplanting corn herbicide.
Acetamide Parents and Degradation Products of Analysis: OGRL LCPD
Acetamide herbicides are used to control weeds in row crops such as corn and soybeans. Acetamide herbicides and their degradates are common contaminants in surface and groundwater. Some of the widely detected acid degradates are on the USEPA contaminant candidate list (CCL).
OGRL Enzyme Linked-Imunnosorbent Assay Methods of Analysis
Immunoassays are rapid screening techinques that can be used to provide data on a specific compound or class of compunds on a large number of samples. We have used these methods to conduct large scale reconnaissance studies of atrazine in rainfall and cyanobacterial toxins in the USEPA national lake and reservoir reconnaissance study.
Organic Geochemistry Research Laboratory Scored High on Proficiency Testing for Glyphosate
In a recent inter–laboratory comparison of 28 international laboratories, the U.S. Geological Survey (USGS) Organic Geochemistry Research Laboratory (OGRL) scored A's for the analysis of glyphosate and aminomethylphosphonic acid (AMPA) in this proficiency testing.
Assessing cell line models for species differences in 6PPD-quinone sensitivity
Coho salmon have been shown to be highly sensitive to the tire transformation chemical 6PPD-quinone, with concentrations contained in stormwater sufficient to induce mortality in up to 90% of the entire fall coho run. Other salmonid species (chinook, sockeye, chum) are much less sensitive to 6PPD-quinone induced mortality. This data examines the varying species sensitivities across salmoids using
Water-quality results from a wastewater reuse study: Inorganic and organic compositions of wastewater effluent and select urban and agricultural water types during rain-induced runoff, Chickasha, Oklahoma, 2018-2019
Oklahoma State University South-Central Research Station (SCRS) was used to conduct research to understand the chemical composition of various water types and their potential environmental and human health effects. The study area provided the opportunity to study five water types: (1) receiving surface water (Washita River), (2) urban stormwater, (3) wastewater treatment plant effluent used for ir
Water-quality data for a pharmaceutical study at Muddy Creek in North Liberty and Coralville, Iowa, 2017-2018
Samples were collected, processed, and analyzed for organics, estrogen equivalents, and fecal indicator bacteria. Filtered organic samples were sent to the National Water Quality Laboratory in Denver, Colorado. Unfiltered estrogen equivalent samples were sent to the Organic Geochemistry Research Lab in Lawrence, Kansas, for extraction, after which they were sent to the National Fish Health Resear
Establishing an in vitro model to assess the toxicity of 6PPD-quinone and other tire wear transformation products
The tire wear transformation product 6PPD-quinone (6PPDQ) has been implicated as the causative factor for broad scale mortality events for coho salmon in the Pacific Northwest. Highly variable sensitivity to 6PPDQ in closely related salmonids complicates efforts to evaluate the broader toxicological impacts to aquatic ecosystems. Our goals were to (1) validate the large range of in vivo species se

Juxtaposition of intensive agriculture, vulnerable aquifers, and mixed chemical/microbial exposures in private-well tapwater in northeast Iowa
In the United States and globally, contaminant exposure in unregulated private-well point-of-use tapwater (TW) is a recognized public-health data gap and an obstacle to both risk-management and homeowner decision making. To help address the lack of data on broad contaminant exposures in private-well TW from hydrologically-vulnerable (alluvial, karst) aquifers in agriculturally-intensive landscapes

Transcriptome signatures of wastewater effluent exposure in larval zebrafish vary with seasonal mixture composition in an effluent-dominated stream
Wastewater treatment plant (WWTP) effluent-dominated streams provide critical habitat for aquatic and terrestrial organisms but also continually expose them to complex mixtures of pharmaceuticals that can potentially impair growth, behavior, and reproduction. Currently, few biomarkers are available that relate to pharmaceutical-specific mechanisms of action. In the experiment reported in this pape

RNA-seq reveals potential gene biomarkers in fathead minnows (Pimephales promelas) for exposure to treated wastewater effluent
Discharged wastewater treatment plant (WWTP) effluent greatly contributes to the generation of complex mixtures of contaminants of emerging concern (CECs) in aquatic environments which often contain neuropharmaceuticals and other emerging contaminants that may impact neurological function. However, there is a paucity of knowledge on the neurological impacts of these exposures to aquatic organisms.
