• Subtle
✓Alter of bee health without killing bees directly
• Occur at lower doses, as compared to lethal effects

Major gaps
1. Monitoring studies and pesticide Risk Assessment are limited […]
2. Monitoring studies are local and not harmonized

• Mitchell et al. 2017 (Science)
• Honey contamination worldwide, but only neonicotinoids
