ABSTRACT Pollinators are exposed to metals while foraging in the landscape and accumulate detectable concentrations of trace within their bodies, although major exposure routes remain unclear. As nectar is main source food for pollinators, we analyzed metal content floral rewards identify if contained may serve as an oral route. Nectar from flowering plant species growing vacant lots city Cleveland, OH, USA was extracted using a centrifuge tested arsenic, cadmium, chromium, lead ICP‐MS. We collected volunteer flower that common pollinator forage plants. varied by species, but not location. arsenic ranged 0 8.44 μg/L, cadmium 32.99 chromium 45.69 135.31 μg/L. The presence these soil contaminants indicates uptake concentration resources likely route pollinators nectar‐feeding animals.
