Noninvasively Collected Fecal Samples as Indicators of Multiple Pesticide Exposure in Wild Birds
Pesticide use poses a potential hazard to wild birds that use agricultural farmland as their foraging habitat. Whereas most current pesticide studies have found residues in liver samples and single active substances, noninvasive sampling methods and data on a wide variety of agrochemicals are needed...
