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.

Cyanotoxin mixtures and taste-and-odor compounds in cyanobacterial blooms from the midwestern united states Cyanotoxin mixtures and taste-and-odor compounds in cyanobacterial blooms from the midwestern united states

The mixtures of toxins and taste-and-odor compounds present during cyanobacterial blooms are not well characterized and of particular concern when evaluating potential human health risks. Cyanobacterial blooms were sampled in twenty-three Midwestern United States lakes and analyzed for community composition, thirteen cyanotoxins by liquid chromatography/mass spectrometry and immunoassay...

Phytoestrogens and mycotoxins in Iowa streams: An examination of underinvestigated compounds in agricultural basins Phytoestrogens and mycotoxins in Iowa streams: An examination of underinvestigated compounds in agricultural basins

This study provides the first broad-scale investigation on the spatial and temporal occurrence of phytoestrogens and mycotoxins in streams in the United States. Fifteen stream sites across Iowa were sampled five times throughout the 2008 growing season to capture a range of climatic and crop-growth conditions. Basin size upstream from sampling sites ranged from 7 km2 to >836,000 km2...

A shift in the dominant toxin-producing algal species in central California alters phycotoxins in food webs A shift in the dominant toxin-producing algal species in central California alters phycotoxins in food webs

In California, the toxic algal species of primary concern are the dinoflagellate Alexandrium catenella and members of the pennate diatom genus Pseudo-nitzschia, both producers of potent neurotoxins that are capable of sickening and killing marine life and humans. During the summer of 2004 in Monterey Bay, we observed a change in the taxonomic structure of the phytoplankton community-the...
