According to Inserm, a molecule used in agricultural fungicides is toxic to the environment and to humans


Researchers had already alerted in 2018 to the dangerousness of this molecule. In vain.

The National Institute of Health and Medical Research (Inserm) shows, in a study published on Thursday and Franceinfo has knowledge, that a molecule used in agricultural fungicides is toxic to the environment and human cells.

These pesticides contain substances called SDHI (for succinate dehydrogenase inhibitors) which have the principle of blocking an enzyme involved in the cellular respiration of fungi. "We show that eight of the eleven SDHI currently authorized in France are toxic to human cells"explains Pierre Rustin, a researcher at Inserm and a member of the CNRS, who took part in this study.

In 2018, researchers had already alerted the dangerousness of this molecule but in January 2019, ANSES (National Agency for Food Safety, Environment and Labor), concluded that there had no evidence to justify a health alert. This time, it is Inserm, a public research organization, some researchers are members of ANSES, which calls into question the authorization of the SDHI.

According to Pierre Rustin, these substances increase the risk of neurological diseases "such as Parkinson's or Alzheimer's", especially for farmers who use these products. The fungicide also has deleterious effects on earthworms and bees.

SDHI is authorized in France and Europe. He enters the preparation of many fungicides. It is used in agriculture, in eleven products authorized in France for wheat, rapeseed but also strawberries, carrots or vines. And on football fields.
