What does the term "bioaccumulation" refer to?

The term "bioaccumulation" specifically refers to the buildup of substances, such as pesticides, in organisms over time. This process occurs when an organism absorbs a substance at a rate faster than it is able to eliminate it. As a result, toxic chemicals can concentrate in the tissues of living organisms, leading to harmful effects on health and the ecosystem.

Understanding bioaccumulation is crucial in pest management because it highlights the potential long-term consequences of pesticide use. When chemicals are introduced into the environment, they can enter the food chain, affecting not only the targeted pest species but also non-target organisms and ultimately humans. This phenomenon underscores the importance of using pest control methods responsibly and considering their ecological impact.
