What does bioaccumulation refer to?

Bioaccumulation specifically refers to the process by which toxic substances, such as heavy metals or pesticides, accumulate in the tissues of living organisms over time. As an organism consumes food, it also takes in these toxic substances, which may not be easily expelled from its body. Consequently, the concentration of toxins within the organism increases, especially as it continues to consume contaminated food over long periods. This phenomenon can lead to higher toxicity levels, which may impact the health of the organism and potentially affect higher trophic levels in the food chain, including predators of the contaminated organism. Understanding bioaccumulation is crucial, particularly in environmental science and public health, as it highlights the risk of long-term exposure to pollutants in various ecosystems.
