Abstract

Agricultural seed-coat treatments are prone to drift as seed coatings may scuff off and become incorporated into field particles during planting. Vacuum planters release exhaust and kick up field dust, laden with systemic pesticides that blow across the landscape, is taken up, and later expressed in the nectar and pollen of surrounding plants. Offsite movements and nontarget exposure to systemic pesticides need attention and determining how and at what exposure levels pollinators are exposed is of critical importance. Unfortunately, this requires extensive and costly instrumental analyses. Here, we describe dust sampling and a modified, rapid method based on liquid chromatography in tandem with mass spectrometry—based method for quantification of a broad array of agrochemicals in captured dust particles. This method increases ability to detect potential exposure to multiple agrochemicals and allows researchers to better address critical knowledge gaps in the environmental fate, off-target movement, and persistence of conventional seed treatments.
