Capillary Gas Chromatography with Four Different Detectors for Dinitroaniline Herbicides in Human Body Fluids

Abstract: A simple and rapid method for extraction of seven dinitroaniline herbicides from human whole blood and urine using Sep-Pak C18 cartridges is presented. After mixing with distilled water, whole blood and urine samples containing the herbicides were loaded on Sep-Pak C18 cartridges and eluted with chloroform-methanol (9:1). The recovery of the seven compounds that were added to whole blood and urine was more than 91%. The herbicides were detected by capillary gas chromatography (GC) with electron-capture detecti… Show more

“…Dessa forma, torna-se primordial a detecção e quantificação desses agroquímicos empregados nas culturas valendo-se de técnicas analíticas, dentre as quais as mais empregadas são: cromatografia líquida de alta e/ou ultra eficiência (HPLC e UPLC) (FENOLL et al, 2012;GHOBADI;YAMINI;EBRAHIMPOUR, 2015;LI et al, 2016), cromatografia gasosa (GC) (KUMAZAWA et al, 1995;TADEO;SÁNCHEZ-BRUNETE, 2013) e espectrometria de massas (MS) (DONG et al, 2016;GOSCINNY, et al, 2012). No entanto, esses estudos deparam-se com problemas analíticos complexos ocasionados pela gama de substâncias existentes a serem determinadas, em geral, presentes em nível de traços (MARQUES;MARQUES;NUNES, 2006).…”
