Biomagnification: Biomagnification is the process where toxins or pollutants become more concentrated as they move up the food chain. It occurs because organisms at higher trophic levels consume larger quantities of prey containing accumulated toxins.
Persistent Organic Pollutants (POPs): POPs are toxic chemicals that resist degradation and persist in the environment for long periods. They tend to bioaccumulate in organisms and can cause adverse effects on ecosystems and human health.
Half-life: The half-life is the time it takes for half of a substance to decay or be eliminated from an organism's body. It helps determine how long a substance will persist in an organism before being reduced by natural processes.
