Differentiate between biodegradable and non-biodegradable pollutants

Differentiate between biodegradable and non-biodegradable pollutants.

Biodegradable Pollutants Non-biodegradable Pollutants
• These pollutants are organic matters and can be decomposed by the activity of microorganisms. • These pollutants are inorganic and they do not decompose.
• But when these substances accumulate in large quantity, microorganisms are unable to decompose them completely and thus they cause pollution. • These substances accumulate and cause tremendous harm to the environment and living organisms.
• Can be recycled naturally or by humans • Cannot be recycled naturally.
• Useful products can be produced after biodegradation. • They remain unchanged or if they take part in chemical reaction, their products are also biodegradable.
• Example: Paper, cow-dung, vegetable peels • Example: DDT, synthetic fibres, plastic, metals, Styrofoam.
