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.

Leaching of Metolachlor, Atrazine, and Atrazine Metabolites into Groundwater

Transactions of the ASAE, 1994
A 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.

Simultaneously enhanced removal and stepwise recovery of atrazine and Pb(II) from water using β-cyclodextrin functionalized cellulose: Characterization, adsorptive performance and mechanism exploration.

Journal of Hazardous Materials, 2020
Heavy metals and pesticides often coexist in contaminated water, while their potential competition behaviors make the adsorptive removal more challenging. Thus, decorating an adsorbent with independent functional sites could be a promising alternative to

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

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

Atrazine removal using chitin-cl-poly(acrylamide-co-itaconic acid) nanohydrogel: Isotherms and pH responsive nature.

Carbohydrate Polymers, 2020
Removal of commonly used pesticide, atrazine was examined by employing chitin based nanohydrogel. Chitin-cl-poly (acrylamide-co-itaconic acid) nanohydrogel was synthesized by microwave method.

Pyrite enables persulfate activation for efficient atrazine degradation.

Chemosphere, 2020
Persulfate (PS) is widely used for environmental remediation, but its organic contaminant removal performance strongly depends on its activation. In this study, we demonstrate that pyrite (FeS2) can more effectively activate PS than the commonly used ...

Urinary atrazine metabolites as indicators for rat and human exposure to atrazine

Toxicology Letters, 1988
Rats 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.

Peroxymonosulfate improved photocatalytic degradation of atrazine by activated carbon/graphitic carbon nitride composite under visible light irradiation.

Chemosphere, 2019
The photocatalytic degradation of atrazine by activated carbon/graphitic carbon nitride composites with peroxymonosulfate (PMS) was investigated under visible light irradiation.
