Zaller & András Székács Environmental Sciences Europe volume 35, Article number: 51 (2023) https://enveurope.springeropen.com/articles/10.1186/s12302-023-00758-9   Abstract Glyphosate (GLY), the most widely used herbicide in the world, is frequently detected in various environmental matrices, including soil, the foundation of agriculture. In practice, … Read more

Glyphosate Effects on Earthworms: Active Ingredients vs. Commercial Herbicides at Different Temperature and Soil Organic Matter Levels

by

Abstract Little is known about the non-target effects of glyphosate active ingredients (GLY) versus glyphosate-based herbicide (GBH) formulations on soil organisms, and whether effects are influenced by environmental conditions. We investigated the avoidance behavior, biomass growth, and reproduction of earthworms (Eisenia fetida, E. andrei) in response to two GLYs (glyphosate ammonium and potassium salt), the … Read more

Glyphosate-Based Herbicide Formulations with Greater Impact on Earthworms and Water Infiltration than Pure Glyphosate

by

Abstract Glyphosate is the most widely used active ingredient (AI) in thousands of glyphosate-based herbicides (GBHs) worldwide. Short-term impacts of AIs or GBHs on earthworms are well known, but few studies have examined long-term legacy effects >3 months after application. In a pot experiment, we studied both short-term and long-term effects on deep burrowing earthworms … Read more

Co-formulants of glyphosate herbicides are endocrine disruptors

by

PR 02/16 Co-formulants of glyphosate herbicides are endocrine disruptors In a new French-Hungarian study, the co-formulants of glyphosate herbicides are shown to be endocrine disruptors, i.e. to interfere with the human hormone system. Two ENSSER board members, Nicolas Defarge and András Székács, are involved in the study. Despite a great deal of scientific criticism pointing … Read more
