New Standardized Procedure to Extract Glyphosate and Aminomethylphosphonic Acid from Different Matrices: A Kit for HPLC-UV Detection. [PDF]

J Xenobiot
Background: Glyphosate has been extensively used as herbicide since the early 1970s. The daily exposure limit is set at 0.3 mg/kg bw/d in Europe and 1.75 mg/kg bw/d in the USA.

Aminomethylphosphonic acid and methoxyacetic acid induce apoptosis in prostate cancer cells. [PDF]

Int J Mol Sci, 2015
Aminomethylphosphonic acid (AMPA) and its parent compound herbicide glyphosate are analogs to glycine, which have been reported to inhibit proliferation and promote apoptosis of cancer cells, but not normal cells. Methoxyacetic acid (MAA) is the active metabolite of ester phthalates widely used in industry as gelling, viscosity and stabilizer; its ...

Adsorption and detoxification of glyphosate and aminomethylphosphonic acid by montmorillonite clays. [PDF]

Environ Sci Pollut Res Int, 2023
The co-occurrence of mixtures of glyphosate (GLP) and aminomethylphosphonic acid (AMPA) in contaminated water, soil, sediment, and plants is a cause for concern due to potential threats to the ecosystem and human health. Major routes of exposure include contact with contaminated water and soil and through consumption of crops containing GLP and AMPA ...

Adsorption of glyphosate and aminomethylphosphonic acid in soils [PDF]

International Agrophysics, 2013
Abstract The results showed that glyphosate is initially adsorbed mostly in the upper 2 cm. It is than transported and adsorbed after few days in deeper soil horizons with concomitant increasing content of its metabolite aminomethylphosphonic acid.

Occurrence and profiles of glyphosate and aminomethylphosphonic acid in paired urine and feces of humans, cats, and dogs. [PDF]

Environ Int
We determined glyphosate and its degradation product, aminomethylphosphonic acid (AMPA), in paired urine and feces of humans (N = 14), cats (N = 10) and dogs (N = 21).

AM1 and ab initio studies of aminomethylphosphonic acid

Journal of Molecular Structure: THEOCHEM, 1991
Abstract The molecular properties of aminomethylphosphonic acid in the zwitterionic and molecular forms were calculated using the AMI and ab initio methods with the STO-3G ∗ , 3-21G ∗ and 6-31G ∗ basis sets at the self-consistent-field and electron-correlation level. It was found that the molecular form of this acid is 10.4 kcal mol −1 more stable

Quantification of glyphosate and aminomethylphosphonic acid from microbiome reactor fluids [PDF]

Rapid Communications in Mass Spectrometry, 2020
Rationale Glyphosate is one of the most widely used herbicides and it is suspected to affect the intestinal microbiota through inhibition of aromatic amino acid synthesis via the shikimate pathway. In vitro microbiome bioreactors are increasingly

Aminomethylphosphonic Acid (AMPA), a Glyphosate Metabolite, Decreases Plasma Cholinesterase Activity in Rats. [PDF]

J Xenobiot
Glyphosate, a widely used herbicide, is linked to a plethora of deleterious effects in both clinical and preclinical studies. Nevertheless, the effects of its main metabolite, aminomethylphosphonic acid (AMPA), whose half-life in soil is even longer than

A method to assess glyphosate, glufosinate and aminomethylphosphonic acid in soil and earthworms [PDF]

Journal of Chromatography A, 2021
A new sensitive and selective analytical methodology to quantify glyphosate (GLY), aminomethylphosphonic acid (AMPA), and glufosinate (GLU) in both soil and earthworms (Allolobophora chlorotica) was developed. The extraction and purification methods were optimized.
