Risk assessment reveals highest toxicity risks from pyrethroid and neonicotinoid residues in bees, highlighting dangerous synergism with fungicides.

Key Points

To comprehensively evaluate the toxicological risks of pesticide residues in pollen and honey to honey bees and bumble bees under dietary, contact, and time-cumulative exposure conditions.
Analyzed recent agrochemical residue survey data across pollen and honey alongside empirical toxicity thresholds for honey bees and bumble bees.
Complemented conventional acute risk assessment frameworks with novel models capturing time-cumulative dietary exposure.
Contact exposure to contaminated pollen containing pyrethroid and neonicotinoid insecticide residues poses the greatest individual toxic risk.
Synergistic interactions between ergosterol-inhibiting fungicides and pyrethroids or neonicotinoids markedly elevate risk despite low co-occurrence in residue surveys.
Dietary ingestion of systemic compounds, notably imidacloprid, thiamethoxam, chlorpyrifos, and cyhalothrin-fungicide combinations, presents significant secondary risks.
