What is bioaccumulation?

Bioaccumulation refers to the gradual accumulation of substances, such as pesticides or heavy metals, in the tissues of living organisms over time. This process occurs when an organism absorbs these substances at a rate faster than it can eliminate them, leading to higher concentrations within the organism compared to the surrounding environment.

This phenomenon is particularly concerning in aquatic ecosystems, where toxins can enter the food web and affect various species, including humans. Animals higher up the food chain may experience even more significant bioaccumulation, a process known as biomagnification, where the concentration of toxins increases as they move up the food chain.

The focus on bioaccumulation emphasizes the importance of monitoring pollutants and understanding their long-term effects on ecosystems and human health. Understanding this concept is vital for pollution responders as they assess environmental risks and develop strategies to mitigate the impact of harmful substances.
