14C tebuconazole degradation in Colombian soils.

Communications in agricultural and applied biological sciences, 2011
Tebuconazole is a fungicide used on onion crops (Allium Fistulosum L) in Colombia. Persistence of pesticides in soils is characterized by the half-life (DT50), which is influenced by their chemical structure, the physical and chemical properties of the soil and the previous soil history.

Stereoselective degradation of tebuconazole in rat liver microsomes

Chirality, 2011
AbstractThe aim of this study was to assess the stereoselectivity of two tebuconazole [(RS)‐1‐p‐chlorophenyl‐4,4‐dimethyl‐3‐(1H‐1,2,4‐triazol‐1‐ylmethyl)pentan‐3‐ol] enantiomers in in vitro system (rat liver microsomes). The analytes were extracted with acetic ether and concentrations were determined by high performance liquid chromatography (HPLC ...

Tebuconazole Sorption in Contrasting Soil Types

Soil and Sediment Contamination: An International Journal, 2013
This study investigates the sorption of tebuconazole in contrasting soil types (Rendzic Leptosol, Haplic Arenosol, and Haplic Cambisol). Tebuconazole was used both as an analytical-grade chemical and as a commercial product. Sorption experiments were performed using the batch equilibrium approach.

Biological monitoring of exposure to tebuconazole in winegrowers

Journal of Exposure Science & Environmental Epidemiology, 2014
Tebuconazole (TEB) is a fungicide widely used in vineyards and is a suspected teratogen for humans. The aim of this research was to identify urinary biomarkers and the best sampling time for the biological monitoring of exposure to TEB in agricultural workers.

Stereoselective degradation of flutriafol and tebuconazole in grape

Environmental Science and Pollution Research, 2014
The stereoselective dissipation of flutriafol and tebuconazole in grape had been studied. A simple and sensitive method for determination of flutriafol and tebuconazole enantiomers in grape was developed by high-performance liquid chromatography on a cellulose tris(3-chloro-4-methylphenylcarbamate) column.

Enantioselective degradation of tebuconazole in cabbage, cucumber, and soils

Chirality, 2011
AbstractThe enantioselective degradation of tebuconazole has been investigated to elucidate the behaviors in agricultural soils, cabbage, and cucumber fruit. Rac‐tebuconazole was fortified into three types of agricultural soils and sprayed foliage of cabbage and cucumber, respectively.

Persistence Behaviour of Fungicide Tebuconazole in a Viticulture Application

Bulletin of Environmental Contamination and Toxicology, 2014
Dissipation pattern and risk assessment of tebuconazole in grapes was studied following two application rates (250 and 500 mL ha(-1)) under tropical humid climatic condition of West Bengal during 2009-2010. Residues of tebuconazole were confirmed by liquid chromatography-mass spectrometry.

Triazole fungicide tebuconazole disrupts human placental trophoblast cell functions

Journal of Hazardous Materials, 2016
Triazole fungicides are one of the top ten classes of current-use pesticides. Although exposure to triazole fungicides is associated with reproductive toxicity in mammals, limited information is available regarding the effects of triazole fungicides on human placental trophoblast function. Tebuconazole (TEB) is a common triazole fungicide that has been

Biodegradation Of Tebuconazole By Bacteria Isolated From Contaminated Soils

Journal of Environmental Science and Health, Part B, 2009
The objective of this work was to isolate bacteria from soil historically exposed to tebuconazole and to evaluate the biodegradation of this fungicide by them. Tebuconazole is a commonly used systemic fungicide of the triazol group, which inhibits the sterol C-14 alpha-demethylation of 24-methylenedihydrolanosterol, a precursor of ergosterol, a cell ...

Sorption of tebuconazole onto selected soil minerals and humic acids

Journal of Environmental Science and Health, Part B, 2012
The aim of the present study was to investigate tebuconazole sorption on common soil minerals (birnessite, ferrihydrite, goethite, calcite and illite) and humic acids (representing soil organic matter). Tebuconazole was used (i) in the commercial form Horizon 250 EW and (ii) as an analytical grade pure chemical.
