Journal of chromatographic science, 45(3), 131-139 (2007-04-28)
A newly developed method for determining three phenoxy acids and one carbamate herbicide in water and soil samples using gas chromatography with mass spectrometric detection is developed. Phenoxy acids are derivatized through a condensation reaction with a suitable aromatic amine.
Tuansheng Shi et al.
Journal of agricultural and food chemistry, 53(6), 2207-2212 (2005-03-17)
Effects of diethyl suberate (DESU), diethyl sebacate (DES), dibutyl suberate (DBSU), dibutyl sebacate (DBS), and tributyl phosphate (TBP) on diffusion of 14C-2,4-dichlorophenoxy butyric acid (2,4-DB) across cuticular membranes (CM) was studied. Astomatous CM were isolated enzymatically from Stephanotis floribunda Brongn.

Pest management science, 61(4), 383-389 (2005-03-08)
Equilibrium sorption of n-alkyl esters (dimethyl suberate, diethyl suberate, diethyl sebacate, dibutyl suberate and dibutyl sebacate) and monodisperse alcohol ethoxylates (diethylene glycol, tetraethylene glycol, pentaethylene glycol, hexaethylene glycol and octaethylene glycol monododecyl ether) between the reconstituted cuticular waxes of Stephanotis

Medicinski arhiv, 59(3), 147-151 (2005-07-07)
Derivatives of chlorophenoxy carboxylic acids have been the first class of herbicides in continuous use since 1947. The main interest for these substances is due to their evident chronic toxicity and carcinogenic effect. On the other hand, they can cause

A bacterial consortium able to degrade the herbicide 4-(2,4-dichlorophenoxy) butyric acid (2,4-DB) was obtained from an agricultural soil of the Argentinean Humid Pampa region which has a history of long-term herbicide use. Four bacterial strains were isolated from the consortium
