INSERM (Institut national de la santé et de la recherche médicale)

In an article published in the journal Environment International, researchers from Inserm (Inserm Unit 1085 - IRSET, the Institute of Research in Environmental and Occupational Health, Rennes), in association with the Laboratory for Developmental and Educational Psychology, LPDE (Rennes 2 University), provide new evidence of neurotoxicity in humans from pyrethroid insecticides, which are found in a wide variety of products and uses. An increase in the urinary levels of two pyrethroid metabolites (3-PBA and cis-DBCA) in children is associated with a significant decrease in their cognitive performances , particularly verbal comprehension and working memory. This study was carried out on nearly 300 mother and child pairs from the PELAGIE cohort (Brittany).
