  25. Neonicotinoids and public health - Neonics are less toxic to humans (less nicotinic receptors for our CNS) - Only few studies (despite that neonics represent 1/3 of the global insecticide market): (non-target species > 1000 publications ; humans < 20 publications) BUT - EPA 2002 then UE then ANSES (2013): Thiacloprid carcinogen - ARLA 2001, 2004, 2007: Three neonics are potential endocrine disruptors - 2012: Genotoxicity and cytotoxicity of neonics - 2012: Neonics have similar effects than nicotine - EFSA 2013: Neuro-developmental risk for humans - 2014: Effects on hepatic enzymes (toxic accumulation of delta-ALA) - 2014: Cytotoxic effects of formulations >> active ingredients, on human cells - 2014: Effects on thyroid and testicles (endocrine disruptor) - 2014: Synergies with other pesticides (pyrethroid and carbamate) - Japan 2014: description of sub-acute effects on poisoned people (hospital) - Japan 2014 & 2015: human urine contains neonics (90% of tested people) - 2015: Another new toxic pathway of neonics on the CNS (glutamate receptors)… Dr. JM Bonmatin (CNRS) France 25 25

  26.  Preventive and massive use  Collapse of pollinators & biodiversity  Very high toxicity to invertebrates  Threats on ecosystem stability  High toxicity to vertebrates  Threats on food production & food security  Very high persistence in soils  High contamination of water (surface & groundwater) The present use of systemic insecticides is not sustainable => Reduce or suspend => integrated pest management (IPM) Dr. JM Bonmatin (CNRS) France 26 26
