Effect of cadmium alone and in combination with butachlor on soil enzymes

Environmental Geochemistry and Health, 2007
The ecological toxicity of cadmium (Cd, 10 mg kg(-1 )of dry weight soil) and butachlor (10, 50 and100 mg kg(-1 )of dry weight soil) in both their single and combined effects on soil urease and phosphatase was studied after 1, 3, 7, 14, 21 and 28 days exposure under controlled conditions in paddy and phaeozem soils.

Rapid Polyelectrolyte‐Based Membrane Immunoassay for the Herbicide Butachlor

Journal of Immunoassay and Immunochemistry, 2005
Oppositely charged water-soluble polyelectrolytes were used in the developed membrane immunoenzyme assay for the herbicide butachlor. High-affinity and rapid binding between polyanion polymethacrylate and polycation poly(N-ethyl-4-vinylpyridinium) was applied to separate reacted and free immunoreactants.

Study on Leaching Transfer of Butachlor in Black Soil

2010 International Conference on E-Product E-Service and E-Entertainment, 2010
Leaching transfer of herbicides was considered as the main control factor of the transfer conversion of pesticides in the soil-water environment. Using Black soil column, we studied the leaching transfer of Butachlor in Black soil. The experiment results showed that leaching amount of Butachlor and the depth of the highest value of butachlor content ...

Comparative proteome analysis of butachlor-degrading bacteria

Environmental Geology, 2007
A Pseudomonas putida strain, named ER1, was isolated from an agricultural soil and found to actively degrade the herbicide butachlor. The enzyme extracted from ER1 could degrade butachlor. Furthermore, incubation of ER1 in a medium containing 50 mg/kg of butachlor after 3 days resulted in the high butachlor-degrading enzyme activity of ER1. Response of

Effect of butachlor (G) on soil enzyme activity

European Journal of Soil Biology, 2014
Soil enzymes play a crucial role in maintaining soil functions. Pesticide application to crop plants can potentially interfere with soil enzyme activity. We evaluated the impact of butachlor (G), a widely used herbicide, on total soil microbial activity and activity of various soil enzymes, including alkaline phosphatase, protease, urease and amidase ...

[The transferability of acetochlor and butachlor in soil].

Huan jing ke xue= Huanjing kexue, 2002
The transferability of acetochlor and butachlor in soil was studied by soil thin layer chromatography. Acetochlor and butachlor were dropped on the glass plate and spreaded soil on the glass plate was collected per 2 cm, then acetochlor and butachlor were analyzed quantitatively by HPlC. When river water was as the spread solution, Rf(relative flow) of

Phylogenetic changes in soil microbial and diazotrophic diversity with application of butachlor

Journal of Environmental Science and Health, Part B, 2013
We investigated changes in population and taxonomic distribution of cultivable bacteria and diazotrophs with butachlor application in rice paddy soils. Population changes were measured by the traditional plate-count method, and taxonomic distribution was studied by 16S rDNA sequencing, then maximum parsimony phylogenic analysis with bootstrapping (1 ...

Exposure to Oxadiazon-Butachlor causes cardiac toxicity in zebrafish embryos

Environmental Pollution, 2020
Oxadiazon-Butachlor (OB) is a widely used herbicide for controlling most annual weeds in rice fields. However, its potential toxicity in aquatic organisms has not been evaluated so far. We used the zebrafish embryo model to assess the toxicity of OB, and found that it affected early cardiac development and caused extensive cardiac damage ...
