How are these environmental risks assessed? What are the alternative solutions?

Pesticides: license to kill?

We are pleased to receive Laura Mamy, research director at INRAE, she participated in the writing of the Ifremer-INRAE ​​report released in May on the impact of phytosanitary products on the environment and Wilfried SanchezDeputy Scientific Director at Ifremer in charge of the theme Contaminants and impacts on the marine environment, co-pilot of the Ocean & Climate priority research program launched in 2021, who also participated in the drafting of this report.

Today’s report

What do we know about the consequences of pesticides on human health? Among farmers, the causal link between exposure to pesticides and the emergence of Parkinson’s disease is proven, making this pathology a recognized occupational disease. However, the neurotoxicity of these phytosanitary products remains poorly understood, whether at the cellular or molecular level. Report in the laboratory of Julien Dairoux, who analyzes this problem with his team at the University of Paris Cité, focusing on the study of carbamates, a family of pesticides that alter the functioning of an enzyme involved in the repair of neuronal cells , and promotes the development of Parkinson’s disease .
