Answer 1

The correct answer is non-biodegradable pollutants.

Key Points

DDT and aluminum cans are both resistant to decomposition by natural processes, meaning they can persist in the environment for long periods of time and cause pollution.
DDT is a persistent organic pollutant (POP) that was once widely used as an insecticide. However, it was banned in many countries due to its harmful effects on the environment and human health.
Aluminum cans, while recyclable, take hundreds of years to decompose naturally if littered or landfilled.

Additional Information

Primary Pollutants: Primary pollutants are directly emitted into the atmosphere from sources such as vehicles, industries, and natural processes.
- Examples: Carbon Monoxide (CO), Sulfur Dioxide (SO₂), Particulate Matter (PM)
Secondary Pollutants: Secondary pollutants are not directly emitted but form in the atmosphere through chemical reactions between primary pollutants and atmospheric compounds.
- Examples: Ground-Level Ozone (O₃), Sulfuric Acid (H₂SO₄)
Biodegradable Pollutants: Biodegradable pollutants are substances that can be broken down or decomposed by natural processes, such as microbial action or exposure to sunlight.
- Examples: Organic Waste, Biodegradable Plastics, Sewage
