Pollinators, including honey bees, are responsible for the successful reproduction of more than 87% of flowering plant species: they are thus vital to ecosystem health and agricultural services world-wide. To investigate honey bee exposure to pesticides, 168 pollen samples and 142 wax comb samples were collected from colonies within six stationary apiaries in six U.S. states. These samples were analyzed for evidence of pesticides. Samples were taken bi-weekly when each colony was active. Each ap...

Many toxicity investigations have evaluated the potential health risks of ingested engineered nanomaterials (iENMs); however, few have addressed the potential combined effects of iENMs and other toxic compounds (e.g. pesticides) in food. To address this knowledge gap, we investigated the effects of two widely used, partly nanoscale, engineered particulate food additives, TiO2 (E171) and SiO2 (E551), on the cytotoxicity and cellular uptake and translocation of the pesticide boscalid. Fasting food...

Abstract The use of engineered nanomaterial (ENMs) has increased dramatically and the possible interaction of these materials with soil-borne organic co-contaminants is largely unknown. Imidacloprid (IMDA) is a neonicotinoid insecticide and one of the most widely used pesticides in the United States and significant concerns have risen due to unknown role of these insecticides in pollinator decline. As such, understanding ENM interactions with these agrochemicals is important. In this study, the ...

Summary Neonicotinoid insecticides are routinely used as seed treatments on most grain and oilseed crops in the USA, yet the extent and likelihood of spread of insecticide residues during planting has not previously been quantified. Honey bees, Apis mellifera, are highly mobile and highly sensitive to neonicotinoid residues, presenting an opportunity to estimate non-target exposures to neonicotinoids in mobile insects. We measured neonicotinoid dust drift during maize sowing and used sites of ma...

The 53rd North American Chemical Residue Workshop was held in July 2016. This is a brief review of the workshop including the awarding of the 2nd NACRW Excellence award to Dr. Andre de Kok. It is also an introduction to a special issue of the Journal of Agricultural and Food Chemistry that presents manuscripts of papers presented at that workshop.
A collaborative study was conducted to evaluate stable isotope dilution assay (SIDA) and LC-MS/MS for the simultaneous determination of aflatoxins B1, B2, G1, and G2; deoxynivalenol; fumonisins B1, B2, and B3; ochratoxin A; HT-2 toxin; T-2 toxin; and zearalenone in foods. Samples were fortified with 12 13C uniformly labeled mycotoxins (13C-IS) corresponding to the native mycotoxins and extracted with acetonitrile/water (50:50 v/v), followed by centrifugation, filtration, and LC-MS/MS analysis. I...

Abstract Systemic insecticides used for ornamental horticulture crops can protect all portions of a plant with long-lasting effects. However, they may be hazardous to pollinators foraging on contaminated nectar or pollen. Two model plant cultivars were chosen based upon their ability to produce large quantities of pollen or nectar, enabling examination of the level of nectar or pollen contamination (e.g., insecticide “residues”) following insecticide treatments, rather than for the need or advis...

Pre-existing pharmaceutical residues in agricultural soils may encounter engineered nanomaterials, resulting in poorly understood co-contamination interactions. In this study, the bioaccumulation and translocation of the pharmaceutical residue carbamazepine (100 μg L−1) in collard greens (Brassica oleracea) was evaluated upon concurrent exposure to pristine or carboxyl-functionalized multiwall carbon nanotubes (pCNTs or cCNTs) at 50 mg L−1 under hydroponic exposure and at 500 mg kg−1 in soil-gro...
