What is bioaccumulation?

Bioaccumulation refers to the process by which specific substances, particularly toxic chemicals, accumulate in the tissues of living organisms over time. This accumulation occurs when the rate of intake of the substances exceeds the rate at which they are eliminated or metabolized.

In the context of bioaccumulation, certain compounds, such as heavy metals or persistent organic pollutants, may enter the bodies of organisms through various routes such as ingestion, inhalation, or dermal contact. Once inside, these substances can be stored in the fatty tissues or organs, leading to higher concentrations of these toxins than are found in the surrounding environment.

Understanding bioaccumulation is essential because it highlights how pollutants can magnify through the food chain, affecting not only individual organisms but also entire ecosystems and potentially posing health risks to humans who consume contaminated organisms.
