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.
Cyanobacterial (Blue-Green Algal) Blooms: Tastes, Odors, and Toxins
Freshwater and marine harmful algal blooms (HABs) can occur anytime water use is impaired due to excessive accumulations of algae. In freshwater, the majority of HABs are caused by cyanobacteria (also called blue-green algae). Cyanobacteria cause a multitude of water-quality concerns, including the potential to produce taste-and-odor causing compounds and toxins that are potent enough to poison...
New Study on Cyanotoxins in Lakes and Reservoirs Provides Insights into Assessing Health Risks
Newly published study provides new evidence of the widespread occurrence of cyanotoxins in lakes and reservoirs of the United States and offers new insights into measures used for assessing potential recreational health risks.
