Bioaccumulation refers to what?

Explanation:
Bioaccumulation is the gradual build-up of toxins in the tissues of an individual organism over time as uptake continues faster than elimination. This happens when contaminants are persistent and not readily broken down, so they accumulate in fatty tissues and organs, leading to internal concentrations that can exceed environmental levels. It differs from rapid elimination or metabolic breakdown, which would reduce the body’s toxin load. It’s also different from simply distributing toxins across a population, which deals with variation among individuals rather than accumulation within one.
