Evaluation of the ecological risk of pesticide residues from the European LUCAS Soil monitoring 2018 survey

Integrated Environmental Assessment and Management, Volume 20, Issue 5, Page 1639-1653, September 2024.
Abstract The 2018 LUCAS (Land Use and Coverage Area frame Survey) Soil Pesticides survey provides a European Union (EU)‐scale assessment of 118 pesticide residues in more than 3473 soil sites. This study responds to the policy need to develop risk‐based indicators for pesticides in the environment.

Distribution of glyphosate and aminomethylphosphonic acid (AMPA) in agricultural topsoils of the European Union

Science of The Total Environment, 2018
Approval for glyphosate-based herbicides in the European Union (EU) is under intense debate due to concern about their effects on the environment and human health. The occurrence of glyphosate residues in European water bodies is rather well documented whereas only few, fragmented and outdated information is available for European soils. We provide the

Polymeric aminomethylphosphonic acids - 1. Synthesis and properties in solution

Designed Monomers and Polymers, 1998
Three water-soluble polyaminomethylphosphonic acids were obtained by radical polymerization in aqueous solution. The corresponding monomers were synthesized by different procedures. A Mannich-type reaction of diallylamine, formaldehyde, and phosphorous acid leads to diallylaminomethylphosphonic acid.
