Morphology

bioaccumulation = accumulation (semi-transparent) = bio + accumulate + ion

The word is built compositionally from the scientific prefix bio- plus accumulation, but the specialized technical meaning is not fully obvious to an average learner.

Etymology

The word bioaccumulation joins bio- 'life' and accumulation 'a build-up', so think of it as a 'build-up in living things'. It means the slow gathering of harmful chemicals or toxins inside animals and plants over time.
