The process by which pollutants accumulate in living organisms is called bioaccumulation. This phenomenon occurs when organisms absorb and retain toxic substances from their environment faster than they can eliminate them. Over time, these pollutants can build up to dangerous levels within the body, posing health risks to the organism itself and to those higher up in the food chain. Bioaccumulation highlights the importance of monitoring and regulating environmental contaminants to protect both wildlife and human health, as these toxins may cause various adverse effects.
