Question

Which of the following is the cause of Biomagnification in human beings?

Options

• Fertiliser run off

• Oil spills

Answer 1

Explanation:

Industrial effluents often contain persistent toxic chemicals and heavy metals (e.g., mercury, arsenic, cadmium, lead) that accumulate in organisms and become more concentrated at each trophic level, so they biomagnify in food chains and can reach humans through contaminated fish and water.
