Question

What can be biomagnification effects on humans?

Answer 1

Biomagnification is the progressive increase in concentration of toxic chemicals up the food chain. Small amounts in water or plants concentrate in fish and then in large predators, including humans. Health effects in people include gastrointestinal irritation, liver and kidney damage, and nervous‑system disorders; certain toxins cause developmental brain damage in children (lead), neurological Minamata disease (mercury), and increased cancer risk from arsenic or asbestos exposure. Chronic exposure can be incapacitating or fatal. Public health monitoring and stricter waste controls and exposure tracking reduce long‑term human harm.
