Definition of Aminomethylphosphonic acid (AMPA):
Aminomethylphosphonic acid is mainly produced by environmental biodegradation reactions of the herbicide glyphosate.
This is the common definition for Aminomethylphosphonic acid (AMPA), other definitions can be discussed in the article
Currently very little is known about AMPA. It is formed by biodegradation of the herbicide glyohosate. Compared to glyohosate; present at lower concentrations in the environment, although it's more stable, it adsorbs more strongly to soils and might have a higher tendency towards bioaccumulation. Glysphosate itself however is not expected to bioaccumulate much because of its higher water solubility.
Measured concentrations of AMPA in surface waters range between 6 and 35 µg/l .
