| Popis: |
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 section of the cartridge showing the good retention capacity of XAD®-2 for these analytes. Method quantification limits were 0.32 and 0.34 µg m-3 for α and β-endosulfan, respectively. These results suggest that the proposed method may be useful for evaluating occupational exposure to these compounds. |
