Scientific works of Jean-Marc Bonmatin are at the interface of chemistry, biology and toxicology. His works mainly focus on:
1) Measurements of exposures to xenobiotic molecules (especially pesticides acting on the central nervous system),
2) Mechanisms of action of neuro-toxicants, and their effects on living systems.
Combination of these two approaches by using a new validated model of eco-toxicological risks, then allows him providing a fine risk assessment, this for both non-target invertebrates, and vertebrates.
Two main classes of insecticides have been extensively studied in the frame of European community research programs: neonicotinoids and phenylpyrazoles. By developing new analytical methods which are the most sensitive so far (LC/GC-MS-MS), JM Bonmatin and co-workers have demonstrated the contamination of pollen and nectar by these insecticides. They also shown that chronic exposure at very low doses induces a significant lethality and a set of sub-lethal effects, including effects on reproduction.
For a better understanding of these issues at the global level, JM Bonmatin has co-created an international expert group of independent researchers (22 countries): The Task Force on Systemic Pesticides (TFSP). The TFSP has published the first meta-analysis on this subject in 2015, with an update from 2017. The comprehensive meta-analysis revealed that systemic insecticides: a) contaminate significantly all compartments of the environment (soil, water, plants and air), and b) severely impact biodiversity (pollinators, terrestrial and aquatic invertebrates, and insectivorous vertebrates species).
In this context, Jean-Marc Bonmatin is involved in risk assessment of emerging issues, as a member of national expert committees (follow the links: Ministry of agriculture, Institute of bees and pollination, Agency of food safety and environment), as well as for international bodies (follow the links: IUCN, IPBES, OECD, and vice-Chair of the TFSP).
Nowadays, JM Bonmatin extends his research interests in pesticide alternatives as well as for occupational-and public-health.
