Sensitive Detection of Neonicotinoid Insecticides and Other Selected Pesticides in Pollen and Nectar Using Nanoflow Liquid Chromatography Orbitrap Tandem Mass Spectrometry

Abstract: In this work, a new method based on nanoflow LC with high-resolution MS was developed for the determination of eight pesticides in pollen and nectar samples, including neonicotinoid insecticides and other selected pesticides commonly found in bees and beeswax. Detection was undertaken with a hybrid quadrupole-Orbitrap mass spectrometer (Q Exactive™) equipped with a commercial nanospray ion source. The extraction of pesticides from pollen samples was performed by a modified micro-QuEChERS method scaled down to … Show more

“…Also, pesticides are commonly used and represent a threat for hummingbirds and other pollinators that consume nectar from coffee flowers. Several authors have documented the presence of insecticide residues (neonicotinoid insecticides) on the nectar and pollen of crops and have mentioned that these could affect pollinators (Dively and Kamel 2012, Thompson et al 2014, Bartlewicz et al 2016, Moreno-González et al 2018. Additionally, Bishop et al (2018) found pesticide compounds in cloacal fluids and fecal pellets of hummingbirds, although they did not comment on the potential effects of exposure.…”
