(Beyond Pesticides, August 6, 2026) In a groundbreaking study on the weed killer glyphosate and glyphosate-based herbicides (GBHs), researchers from Argentina find multigenerational effects from perinatal (shortly before and after birth) exposure in rats. Previous research, published in Environmental Research, finds that glyphosate’s primary metabolite (AMPA) induces DNA damage through oxidative stress among subpopulations of primary school children. This study is one of the first to identify oxidative stress from AMPA exposure among children in a nonoccupational setting. However, glyphosate and its formulations have long been associated with oxidative stress and strong evidence of genotoxicity.
