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 .
