Aminomethylphosphonic acid (AMPA) - one of glyphosate's main metabolites has been classified as persistent in soils, raising concern regarding the widespread use glyphosate agriculture and forestry. Glyphosate may have negative or neutral effects on soil biota, but no information is available toxicity AMPA to invertebrates. Therefore our aim was study effect mortality reproduction earthworm species Eisenia andrei using standard ecotoxicological methods (ISO). Field-relevant concentrations had significant acute chronic assays. Except at highest concentration tested, a biomass loss observed compared controls assay. The number juveniles cocoons increased with higher applied, their mean weights decreased. This mass indicates sensitivity than adults AMPA. Our results suggest that earthworms coming from parents grown contaminated soils reduced growth, limiting beneficial roles key ecosystem functions. Nevertheless, further research needed better understand mechanisms underlying sublethal here.
