Kinetics and mechanisms of radiation-induced degradation of acetochlor

Chemosphere, 2005
The radiation-induced degradation of acetochlor was investigated in this work. In a mixed solvent composed of acetonitrile and water at a ratio of 20/80 in volume, the acetochlor degradation rate was proportional to the radiation dose rate and acetochlor concentration.

Degradation of acetochlor by consortium of two bacterial strains and cloning of a novel amidase gene involved in acetochlor-degrading pathway

Bioresource Technology, 2013
Two bacterial strains Sphingobium quisquiliarum DC-2 and Sphingobium baderi DE-13 were isolated from activated sludge. Acetochlor was transformed by S. quisquiliarum DC-2 to a transitory intermediate 2-chloro-N-(2-methyl-6-ethylphenyl)acetamide (CMEPA), which was further transformed to 2-methyl-6-ethylaniline (MEA), and MEA could not be degraded by ...

Impact of acetochlor on ammonia-oxidizing bacteria in microcosm soils

Journal of Environmental Sciences, 2008
Acetochlor is an increasingly used herbicide on corn in North China. Currently, the effect of acetochlor on soil ammonia-oxidizing bacteria (AOB) communities is not well documented. Here, we studied the diversity and community composition of AOB in soil amended with three concentrations of acetochlor (50, 150, 250 mg/kg) and the control (0 mg ...

Acetochlor as a soil pollutant

Environmental Science and Pollution Research, 2002
Acetochlor is a widely used herbicide all over the world. Similarly to other organic pollutants, the environmental fate of the acetochlor is strongly related to its adsorption properties. Static adsorption equilibrium measurements were carried out at 25 degrees C on different types of Hungarian soils characterized by varying amounts of organic matter ...

Applicator exposure to acetochlor based on biomonitoring

Regulatory Toxicology and Pharmacology, 2005
Biomonitoring was used to assess the combined dermal, oral, and inhalation exposure associated with the agricultural use of Harness Plus, an emulsifiable concentrate formulation of the herbicide acetochlor. Twenty Spanish farmers handled and applied acetochlor to maize in the spring of 2003, following the product label recommendations. Open- and closed-

Phytoremediation of acetochlor residue by transgenic Arabidopsis expressing the acetochlor N-dealkylase from Sphingomonas wittichii DC-6

Science of The Total Environment, 2020
Transgenic engineering is an effective way for plants to obtain strong degradation or detoxification abilities to target pollutants. Acetochlor is an important and widely used herbicide, however, its residue is persistent in soil and is toxic to humans and rotation crops.

Atmospheric OH oxidation chemistry of trifluralin and acetochlor

Environmental Science: Processes & Impacts, 2019
Herbicides react with atmospheric OH, producing multiple oxidation products, including HNCO; these products contribute little to secondary organic aerosol.

Biodegradation of Acetochlor by a Newly Isolated Pseudomonas Strain

Applied Biochemistry and Biotechnology, 2015
A novel microbial strain JD115 capable of degrading acetochlor was isolated from the sludge of acetochlor manufacture and was identified as Pseudomonas aeruginosa species. This strain was able to grow on acetochlor as the sole source of both carbon and nitrogen.

The Acetochlor Registration Partnership: Prospective Ground Water Monitoring Program

Journal of Environmental Quality, 2005
ABSTRACT The Acetochlor Registration Partnership conducted a prospective ground water (PGW) monitoring program to investigate acetochlor [2‐chloro‐ N ‐(ethoxymethyl)‐ N ‐(2‐ethyl‐6‐methylphenyl)‐acetamide] transport to ground water at ...

Degradation Pathways of Acetochlor by γ-Radiolysis

Chemistry Letters, 2004
Abstract The degradation of acetochlor by γ-irradiation was investigated. Acetochlor was decomposed with an efficiency of 40% with a dose rate of 92 Gy min−1 in 2 h. Its radiolytic products under oxidative and reductive conditions were analyzed by GCMS and FTIR.
