The advantage of a toxicokinetic model of the honey bee colony in the context of the risk assessment of plant protection products
Abstract
Within the current discussions about risk assessment of plant protection products regarding honey bees, one of the most important aspects is how to link pesticide exposure on field and landscape scale to potential effects within the colony. A dynamic toxicokinetic model may help to improve the evaluation of dose rates individuals are exposed to through various compartments of the colony, which may result from the application of plant protection products in the field. In addition, it may help to interpret the significance of ecotoxicological test results, especially from lower-tier studies, in the risk assessment and help to refine the exposure assessment and risk evaluation. Linking it to a realistic population model and a landscape-based foraging model would give an improved insight into the dynamics in a honey bee colony under exposure of plant protection products
