Degradation of acetochlor by four microbial communities

Bioresource Technology, 2008
Four microbial communities capable of degrading acetochlor, designated A, D, E, and J, were obtained from acetochlor-contaminated soil and sludge. Acetochlor at an initial concentration of 55mg/L was completely degraded by the four mixed cultures after 4 days.

The Acetochlor Registration Partnership: Prospective Ground Water Monitoring Program

Journal of Environmental Quality, 2005
ABSTRACTThe 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 eight sites. The distribution of soil textures among these sites was weighted toward coarser soil types, while also ...

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-

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.

Mepiquat–acetochlor formulations: sorption and leaching

Applied Clay Science, 2001
Our aim was to study the adsorption of the plant regulator mepiquat to montmorillonite and test the suitability of montmorilonite–mepiquat complexes in formulations to reduce leaching of the non-polar herbicide, acetochlor. Adsorption of the monovalent organic cation mepiquat to montmorillonite through a range of ionic strengths was determined and ...

Acetochlor sorption and degradation in limestone subsurface and aquifers

Pest Management Science, 2010
AbstractBACKGROUND: Acetochlor, introduced on the market in 1994, is used extensively worldwide, but sorption and degradation studies, including subsurface, are scarce, and there appear to be no such studies with aquifer sediment according to the present mini‐review.

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.

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.

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 State Ground Water Monitoring Program

Journal of Environmental Quality, 2005
ABSTRACTThe Acetochlor Registration Partnership (ARP) conducted a 7‐yr ground water monitoring program at a total of 175 sites in seven states: Illinois, Indiana, Iowa, Kansas, Minnesota, Nebraska, and Wisconsin. While acetochlor [2‐chloro‐N‐(ethoxymethyl)‐N‐(2‐ethyl‐6‐methylphenyl)‐acetamide] was the primary focus, the analytical methods also ...
