Degradation and Adsorption of Fosthiazate in Soil

Journal of Agricultural and Food Chemistry, 2004
Adsorption and degradation behavior of a pesticide in soil has a strong effect on its environmental fate as well as efficacy for pest control. Fosthiazate is an organophosphate compound that is currently under development as a nonfumigant nematicide. In this study, we evaluated adsorption and degradation kinetics of fosthiazate in three U.S. soils with

Degradation kinetics of glucosinolates in soil

Environmental Toxicology and Chemistry, 2006
Abstract Glucosinolates are compounds produced by all cruciferous plants. They can be hydrolyzed to several biologically active compounds and, as such, may serve as naturally produced pesticides. To optimize the pesticidal (biofumigation) effect and to assess the risk of glucosinolate leaching and spread in the environment, the ...

Simazine: Degradation by Soil Microorganisms

Science, 1963
A soil fungus, Aspergillus fumigatus Fres., is effective in the degradation of the herbicide 2-chloro-4,6-bis(ethylamino)- s -triazine (simazine). The degradation of both ring- and chain-labeled (C 14 ) simazine was observed in an unamended and an amended (sucrose ...

Study of the Degradation of Polydimethylsiloxanes on Soil

Environmental Science & Technology, 1995
The degradation of polydimethylsiloxanes (silicones) on a spiked standard soil matrix has been studied. Spiked soil was extracted to recover silicones, and the extract was examined by several analytical techniques, including gel permeation chromatography and high-pressure liquid chromatography with an inductively coupled plasma emission spectrometer as

Agricultural Soil Degradation in Croatia

2022
Croatian agriculture has a small impact on the country’s economy (around 4% of the Croatian Gross Domestic Product), but agricultural activities affect agricultural land and reduce quality and productivity. The types of land degradation are not distributed equally in the territory, considering an environmental diversity between the Mediterranean ...

Carbofuran degradation in soil profiles

Journal of Environmental Science and Health, Part B, 1997
Two soils, Puyallup fine sandy loam from Puyallup, WA, and Ellzey fine sand from Hastings, FL, each with a prior history of carbofuran exposure but with different pedological and climatological characteristics, were found to exhibit enhanced degradation toward carbofuran in surface and subsurface soil layers.

Dieldrin: Degradation by Soil Microorganisms

Science, 1967
An attempt was made to discover microorganisms that degrade dieldrin, an extremely stable chlorinated hydrocarbon insecticide. Examination of more than 500 isolates from soil that had been heavily contaminated with various insecticides revealed the existence of a few microbes that are very active in degrading this compound to various metabolites.

Enantioselective degradation of warfarin in soils

Chirality, 2011
AbstractEnvironmental enantioselectivity information is important to fate assessment of chiral contaminants. Warfarin, a rodenticide and prescription medicine, is a chiral chemical but used in racemic form. Little is known about its enantioselective behavior in the environment.

Soil Degradation

2008
Soil degradation is defined as physical, chemical and biological deterioration of soil, is likely to be the most im-portant problem for human nutritional demand in future. Increasing world population and reduction in agricultural land are serious thread for future. Therefore, in order to satisfy nutritional demands, it is important to protect soil, the

Anaerobic degradation of nonylphenol in soil

Journal of Environmental Science and Health, Part B, 2007
This study investigated the effects of various factors on the anaerobic degradation of nonylphenol (NP) in soil. The results show that the optimal pH for NP degradation was 7.0 and that the degradation rate was enhanced when the temperature was increased. The addition of compost enhanced NP degradation.
