“…Dentre elas destacam-se a cromatografia gasosa (CG) acoplada a detector seletivo de captura de elétrons (DCE) 1,5,6 ou acoplada ao detector de massas no modo de seleção de íons [7][8][9] e a cromatografia líquida de alta eficiência (CLAE), acoplada a detector ultravioleta (UV) 10 . Atualmente são encontrados inúmeros trabalhos de monitoramento de resíduos de piretróides em águas 4,11,12 , solos [13][14][15] e alimentos 10,16,17 utilizando as mais diversas técnicas de extração e análise.…”

“…13 Also various organic and inorganic chemicals are possibly bound to dietary fiber in the GIT and quickly excreted in the stools. 14,15 Generally the residual pyrethroid levels in different matrices are determined using chromatographic methods, mainly gas chromatography with electron-capture 5 (GC-ECD) or mass spectrometry detection (GC-MS), [16][17][18] and liquid chromatography has also been employed in some studies. 19,20 Nevertheless electron-capture detection (ECD) is the most frequently selected system for the determination of pyrethroid residues, being especially suitable for the determination of those pyrethroids which possess a chloro atom (cypermethrin, permethrin), bromo atom (deltamethrin), fluoro atom (cyhalothrin), or chloro and fluoro atoms (fluvalinate) in their structure.…”

“…Additionally, the high number of theoretical plates available when using capillary stationary phases in GC allowed for an easy separation of the cis-isomers and trans-isomers in relatively short method run times [7]. Ramesh and Ravi used both NCI and electron ionization for the quantitation of PERM in whole blood [9,13]. Using NCI they were able to decrease the LOQ of method to 0.02 ng/ml from the 0.2 ng/ml levels that were achieved when using electron ionization.…”
