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 ...

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.

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.

Acetochlor sorption and degradation in limestone subsurface and aquifers

Pest Management Science, 2010
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. Sorption, degradation and mineralisation of acetochlor were investigated in heterogeneous limestone down ...

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.

Determination of the herbicide acetochlor by fluorescence polarization immunoassay [PDF]

open access: possibleJournal of Analytical Chemistry, 2005
A fluorescence polarization immunoassay procedure was developed for determining the herbicide acetochlor from the group of chloroacetanilides. Conjugates of fluorescent labeled acetochlor derivatives (tracers) with glycylaminofluorescein and ethylenediaminofluorescein were synthesized.

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 ...
