Organic Geochemistry Research Lab

(OGRL)

The U.S. Geological Survey (USGS) Kansas Water Science Center Organic Geochemistry Research Laboratory (OGRL) was established in 1987. The OGRL is a multidisciplinary program that contributes knowledge about the distribution, fate, transport, and effects of new and understudied organic compounds that may affect human health and (or) ecosystems. 

The OGRL consists of two units: Algal and Other Environmental Toxins (AET) Unit and Environmental Organic Chemistry (EOC) Unit. The OGRL does independent and collaborative research, develops robust analytical methods, and provides fee-for-service analytical laboratory analyses.

Algal and Other Environmental Toxins Unit

The Algal and Environmental Toxins Unit has the capability to detect toxins that could be harmful to human health and the environment.

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.

Occurrence of antibiotics in water from fish hatcheries Occurrence of antibiotics in water from fish hatcheries

The recent discovery of pharmaceuticals in streams across the United States (Kolpin and others, 2002) has raised the visibility and need for monitoring of antibiotics in the environment. Possible sources of antibiotics and other pharmaceuticals in streams may include fish hatcheries. This fact sheet presents the results from a preliminary study of fish hatcheries across the United States...

Accurate mass analysis of ethanesulfonic acid degradates of acetochlor and alachlor using high-performance liquid chromatography and time-of-flight mass spectrometry Accurate mass analysis of ethanesulfonic acid degradates of acetochlor and alachlor using high-performance liquid chromatography and time-of-flight mass spectrometry

Degradates of acetochlor and alachlor (ethanesulfonic acids, ESAs) were analyzed in both standards and in a groundwater sample using high-performance liquid chromatography-time-of-flight mass spectrometry with electrospray ionization. The negative pseudomolecular ion of the secondary amide of acetochlor ESA and alachlor ESA gave average masses of 256.0750??0.0049 amu and 270.0786??0.0064...

Parasite (Ribeiroia ondatrae) infection linked to amphibian malformations in the western United States Parasite (Ribeiroia ondatrae) infection linked to amphibian malformations in the western United States

Parasites and pathogens can influence the survivorship, behavior, and very structure of their host species. For example, experimental studies have shown that trematode parasites can cause high frequencies of severe limb malformations in amphibians. In a broad-scale field survey covering parts of California, Oregon, Washington, Idaho, and Montana, we examined relationships between the...
