Oxidative stress response in atrazine-degrading bacteria exposed to atrazine

Journal of Hazardous Materials, 2012
Rhodobacter 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 ...

The Economics of Atrazine

International Journal of Occupational and Environmental Health, 2007
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, 1973
The 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, 1993
A 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, 1992
Abstract 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

Epidemiology of Atrazine

1995
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
