Determination of isotianil in brown rice and soil using supercritical fluid extraction and gas chromatography/mass spectrometry.

چکیده
Isotianil (3,4-dichloro-2'-cyano-1,2-thiazole-5-carboxanilide) is a new plant-activating pesticide. Usage of the pesticide was approved for rice fields in 2010 and its production increased 400 times (2 × 10(4) kg) in the next year. In this work, a method for determining isotianil in brown rice and rice field soil was investigated for the first time. Isotianil was extracted by supercritical fluid extraction and measured by gas chromatography/mass spectrometry. Isotianil was successfully analyzed with good recoveries (95.1-99.3%) even from soil samples with strong adsorption of pesticides.

A method is developed for the determination of melengestrol acetate in bovine fat tissue at or less than the established tolerance level of 25 ppb. The procedure uses a combination of supercritical fluid extraction (SFE) and solid-phase extraction (SPE) techniques to produce an extract suitable for analysis with either high-performance liquid chromatography with ultraviolet detection or gas chr...

Mycotoxins are secondary metabolites of several species of fungi. The health implications o f mycotoxins are far reaching, ranging from induction of emesis in livestock to warranting classification as a known human carcinogen by the U.S. Environmental Protection Agency (USEPA). There exists inherent difficulty in analyzing several mycotoxins simultaneously due to differences in chemical structu...
