Leaching of Metolachlor, Atrazine, and Atrazine Metabolites into Groundwater
Transactions of the ASAE, 1994A three-year field study was undertaken between 1988 and 1990 to investigate the leaching of metolachlor, atrazine and two of its N-dealkylated products, deethylatrazine and deisopropylatrazine, into the groundwater zone of two agricultural soils of Eastern Canada, a St-Amable sand and a St-Laurent clay.

It is often claimed that atrazine is of great economic benefit to corn growers, but support for this claim is limited. Some cost-benefit studies have assumed that atrazine boosts corn yields by 6%; an extensive review found a 3%-4% average yield increase; other research suggests only a 1% yield effect.

Chronically exposed workers in chemical plants have revealed no increased incidence of benign or malignant disease attributable to atrazine. Some case-control studies showed a slight increase of non-Hodgkin's lymphoma (NHL) incidence while others were negative. Weighted evidence supports no causal association of malignant changes in farming populations

Adsorption of Atrazine on Smectites
Soil Science Society of America Journal, 1992Abstract Smectites may strongly influence the fate of pesticides in soils due to their large surface area and abundance in agricultural soils. This research was undertaken to determine the effects of smectite properties on the affinity of smectitic clays for atrazine (2‐chloro‐4‐ethylamino‐6‐isopropylamino‐1, 3, 5

The unequivocal presence of residues of atrozine and metolachlor in ground water of the Ardas valley in North Greece justified the scientific need to further investigate the conditions and mechanisms responsible for the presence of these compounds in groundwater.

Wet peroxide degradation of atrazine
Chemosphere, 2004The high temperature (150-200 degrees C), high pressure (3.0-6.0 MPa) degradation of atrazine in aqueous solution has been studied. Under these extreme conditions atrazine steadily hydrolyses in the absence of oxidising agents. Additionally, oxygen partial pressure has been shown not to affect atrazine degradation rates.

Sol−Gel Matrixes Doped with Atrazine Antibodies: Atrazine Binding Properties
Chemistry of Materials, 1997Sol−gel materials with antibody properties are described. These were constructed by the entrapment of monoclonal anti-atrazine antibodies (Mabs) in SiO2 sol−gel derived matrixes, which successfully...

N-Nitrosamine formation from atrazine
Bulletin of Environmental Contamination and Toxicology, 1976Previous studies have focused on N-nitroso derivatives of relatively non-persistent pesticides or pesticides that form unstable N-nitroso derivatives. We feel that more persistent pesticides or their degradative products capable of forming N-nitroso derivatives should be investigated.

A high performance liquid chromatography method has been used to study the plasma kinetics of atrazine in a human fatality after ingestion of a herbicide mix containing atrazine, aminotriazole, ethylene glycol and formaldehyde. A hemodialysis was performed in an effort to eliminate these toxic substances. The mean atrazine clearance over 4 h was 250 mL/
