Abstract:Recebido em 19/9/12; aceito em 5/3/13; publicado na web em 24/5/13 VOLATILIZATION CHAMBER: AN ALTERNATIVE FOR EVALUATING THE SAMPLING EFFICIENCY OF α-AND β-ENDOSULFAN IN THE GAS PHASE. The efficiency of XAD ® -2 resin in sampling the pesticides α and β-endosulfan from air contaminated in the laboratory was evaluated. Sampling efficiency ranged from 87 to 108% for α-endosulfan and from 71 to 84% for β-endosulfan with relative standard deviation lower than 19%. The pesticides were not detected in the second sect… Show more
