Metabolic profiling of Lolium perenne shows functional integration of metabolic responses to diverse subtoxic conditions of chemical stress [PDF]

open access: yes, 2015
International audiencePlant communities are confronted with a great variety of environmental chemical stresses. Characterization of chemical stress in higher plants has often been focused on single or closely related stressors under acute exposure, or ...

Effects of the herbicide Roundup on freshwater microbial communities: a mesocosm study [PDF]

open access: yes, 2007
The impact of the widely used herbicide glyphosate has been mainly studied in terrestrial weed control, laboratory bioassays, and field studies focusing on invertebrates, amphibians, and fishes.

Foliar-applied glyphosate substantially reduced uptake and transport of iron and manganese in sunflower (helianthus annuus L.) plants [PDF]

open access: yes, 2006
Evidence clearly shows that cationic micronutrients in spray solutions reduce the herbicidal effectiveness of glyphosate for weed control due to the formation of metal-glyphosate complexes.

ADSORPTION OF GLYPHOSATE AND AMPAIN AGRICULTURAL SOILS

open access: yesEQA, 2013
Immediately after application glyphosate is mostly adsorbed in the upper 2 cm of soils, and is then transported and adsorbed after few days in deeper soil horizons with concomitant increasing content of its metabolite aminomethylphosphonic acid (AMPA ...

AMPA-15N – Synthesis and application as standard compound in traceable degradation studies of glyphosate

open access: yesEcotoxicology and Environmental Safety, 2021
Stable isotope labeling of pollutants is a valuable tool to investigate their environmental transport and degradation. For the globally most frequently used herbicide glyphosate, such studies have, so far, been hampered by the absence of an analytical ...

Effect of a glyphosate-containing herbicide on Escherichia coli and Salmonella Ser. Typhimurium in an in vitro rumen simulation system [PDF]

open access: yes, 2019
Glyphosate (N-(phosphonomethyl)glycine) is the most-used herbicide worldwide. Many studies in the past have shown that residues of the herbicide can be found in many cultivated plants, including those used as livestock feed.

Efficient Red Light–Driven Singlet Oxygen Photocatalysis with an Osmium‐Based Coulombic Dyad

open access: yesAngewandte Chemie, Volume 137, Issue 35, August 25, 2025.
Red light‐absorbing bichromophores with straightforward preparation and superior photocatalytic activity were developed. Spectroscopic studies provided deep insights into the intra‐ion‐pair energy transfer key step and the novel approach. Abstract Photoactive osmium complexes are widely used sensitizers for the generation of singlet oxygen because they
