New red card for pesticides. On Wednesday June 30, a group of multidisciplinary researchers from the National Institute of Health and Medical Research (Inserm) updated their knowledge on the dangerousness of pesticides. This new expertise takes stock of knowledge on the links between exposure to pesticides and human health through a critical analysis of the international scientific literature. In total, more than 5,300 documents were analyzed by a multidisciplinary group of researchers.
Prostate cancer and Parkinson’s disease
In adults, Inserm confirms a “strong presumption” a link between occupational exposure to pesticides and four pathologies. These diseases include: non-Hodgkin lymphoma (NHL), multiple myeloma, prostate cancer and Parkinson’s disease. But that’s not all. Links have also been identified between this occupational exposure and two other diseases: cognitive impairment and chronic obstructive pulmonary disease / chronic bronchitis.
“A presumption of a moderate link was also demonstrated between exposure to pesticides, mainly among professionals, and Alzheimer’s disease, anxiety-depressive disorders, certain cancers (leukemia, central nervous system, bladder, kidney, soft tissue sarcomas), asthma and thyroid pathologies “, adds Inserm in its new recommendations.
Beware of exposure in childhood
The expert group also looked at the consequences of exposure during pregnancy and early childhood. Recent results make it possible to specify the type of childhood leukemia concerned duringmaternal exposure during pregnancy. “A new link has been demonstrated between the risk of acute lymphoblastic leukemia in the event of paternal occupational exposure during the preconception period (moderate presumption)”, warns Inserm. It also confirms a “strong presumption” of a link between central nervous system tumors and parental occupational exposure to pesticides during the prenatal period. A “strong presumption” has also been confirmed between central nervous system tumors and household exposure to pesticides during pregnancy or childhood.
Other analyzes focus on the links between occupational or environmental exposure of mothers during pregnancy and neuropsychological development disorders and motor of the child. “They confirm the existence of a link with a strong level of presumption, in particular for certain families of pesticides, such as organophosphates,” Inserm reports. Thus, for the experts, the highlighting of strong presumptions of links between certain pathologies and exposure to pesticides should encourage better consideration of these issues by the authorities.
