Oxidative stress response in atrazine-degrading bacteria exposed to atrazine
Journal of Hazardous Materials, 2012Rhodobacter sphaeroides W16 and Acinetobacter lwoffii DNS32 which were isolated from soil in cold area subjected to a long-term atrazine application in Heilongjiang Province (China) can degrade atrazine efficiently. The investigation of their antioxidant properties will be useful for bioremediation and engineering applications of atrazine-degrading ...

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.

Atrazine metabolism in sorghum. Catabolism of the glutathione conjugate of atrazine
Journal of Agricultural and Food Chemistry, 1973The major pathway of atrazine metabolism in intact sorghum was shown to involve the following steps: atrazine 'right arrow' S-(4-ethylamino-6-isopropylamino-1,3,5-triazin-2-yl)glutathione 'right arrow' gamma -glutamyl-S-(4-ethylamino-6-isopropylamino-1,3,5-triazin-2-yl)cysteine 'right arrow' S-(4-ethylamino-6-isopropylamino-1,3,5-triazin-2-yl cysteine '

Dimerization constants of atrazine and trifluoromethyl-labeled atrazine
The Journal of Physical Chemistry, 1993A nonlinear optimization procedure is developed to find the dimerization constants of atrazine from the NMR chemical shifts of four of its NH protons. The NH protons identify four active sites which interact pairwise by cooperative association to form a total of 10 hydrogen-bonded dimers.

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

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.

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

Urinary atrazine metabolites as indicators for rat and human exposure to atrazine
Toxicology Letters, 1988Rats were given atrazine (2-chloro-4-ethylamino-6-(isopropylamino)-s-triazine) in drinking water for 1 or 3 weeks at 0.1 (0.45 mM), 0.2 (0.9 mM) or 0.5 g/l (2.3 mM) concentrations of the commercial agent. They excreted at both time points as the principal metabolite 2-chloro-4-ethylamino-6-amino-s-trazine in a dose-dependent fashion.
