“…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 7-9 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.…”

“…Glass fibre [12], Teflon [13], Nylon [14], or cellulose ester filters [9] of 0.45-or 0.7-pm pore size are usually used for this purpose. Some pesticides can, however, be adsorbed by membrane filters, depending on the hydrophobic character of these compounds [9]. These losses are not detected when samples are fortified after filtration, leading to mistakes in the determination.…”

“…Although filtration under gravity is typically used to eliminate SPM from samples [8], losses of the pesticides as a result of adsorption by filter membranes have been reported [9]. Adsorption problems are especially important for isodrin, p,p'-DDE, p,p'-DDT, ~-and 7-chlordane, aldrin, and heptachlor.…”
