It is well established that nanopesticides offer a significantly improved performance compared to their conventional counterparts, also because they allow for precision farming with precise dosing and controlled release factors and environmental triggers that allow for best timing of effects. Studies have shown evidence for improved germination, plant metabolism, physiology, and thus food quality, and for bolstering resilience against pests and weather. Advanced nanomaterials have been shown to improve crop production and soil condition. Nevertheless, research into this nanotechnology application has just begun. The environmental risk assessment (ERA) of PPPs (Plant Protection Products) follows a tiered approach. For soil invertebrates, currently two steps are used: Tier 1, assessment based on reproduction toxicity tests with earthworms, springtails, and predatory mites; Tier 2, field studies as a higher‐tier option, can be conducted in case unacceptable risk is identified at Tier 1. Intermediate tiers are not implemented, and this is a major gap. Hence, our concept builds on these learned lessons. We will on this exploratory project execute a case study where the key elements include 1) Advanced Material (AdMa, nanopesticide), characterization and environmental fate, 2) Hazard assessment via Tier 1: standard species test and, 3) Hazard assessment via intermediate Tier: climate change scenario, 4) Risk Assessment and input for 5) regulatory purposes and recommendations. We will combine knowledge on NMs science state-of-the art, focussing on a proof of concept to generate the core set of data needed for RA that properly integrates the specific impacts of material characteristics in fate and effect assessment, for regulatory purposes – a current gap.
