Decomposed Gosling Feet Provide Evidence of Insecticide Exposure

摘要: Canada goose goslings were exposed to turf sprayed with DZN diazinon 50W application (2.24 kg a.i./ha). The control plot was subjected a water application. One foot from each bird placed outdoors for 7 d decompose and the other kept frozen. Diazinon residues analyzed on both feet. Results showed that detected undecomposed decomposed feet of birds. below level detection (<0.01 ppm, a.i.) goslings. Decomposed may be used determining insecticide exposure when traditional matrices are not available.
