“Biomagnification or biological magnification is the process of accumulation of certain chemicals in living organisms to a concentration higher than that occurring in the inorganic, non-living environment.”
Human beings occupies the top place of most trophic level and we know that concentration of harmful chemicals increase as we go above the trophic level. Therefore human beings are most adversely affected by biological magnification.
Humans may also be affected due to the consumption of fish and shellfish.
