Abstract
Propoxur was extracted from brown tree snakes (Boiga irregularis) and analyzed by reversed-phase high-performance liquid chromatography. Pro poxur was quantified by UV absorbance at 270 nm and fluorescence with excitation at 225 nm and emission at 305 nm. Recovery data were determ ined by analyzing propoxur-fortified blank homogenized tissue. The mea n recovery of propoxur in whole body brown tree snakes was 86.7 +/- 7. 8% for the concentration range of 0.1 to 250 mu g/g. The method limit of detection with fluorescence and UV detection was 9 and 100 ppb, res pectively.
