There are a few references that say glyphosate doesn't bioaccumulate well due to the chemical's "ionized state, its low octanol-water partition coefficient"[1].

There are a few references that say glyphosate doesn't bioaccumulate well due to the chemical's "ionized state, its low octanol-water partition coefficient"[1]. However there are others that suggest glyphosate may bioaccumulate in biofilm consuming invertebrates, where biofilms concentrate glyphosate and prevent the chemical from being retained in surrounding water[2]. Personally, these concepts are newer to me and I'm not sure what to make of it all yet.
