Quarterly-SFG-Jan-to-March
Red Book

[A] Only one

[B] Only two

[C] All the three

[D] None

Answer: C
Notes:

Exp) Option c is the correct answer.

Option I is correct: Cigarette Butts:

Cigarette filters are predominantly made from cellulose acetate, a man – made plastic derived from cellulose.

While it may resemble cotton, it’s actually a form of plastic that is slow to degrade. When discarded, these filters can leach toxic substances like nicotine and heavy metals into the environment, posing risks to wildlife and ecosystems

Option II is correct: Eyeglass Lenses

Modern eyeglass lenses are commonly crafted from plastic materials such as CR-39 (Columbia Resin #39) and polycarbonate. CR-39 is a lightweight plastic offering good optical clarity, while polycarbonate is known for its impact resistance and UV protection

Option III is correct: Car Tyres

Tyres contain both natural rubber and synthetic rubber, the latter being derived from plastic polymers like styrene-butadiene rubber (SBR) and polybutadiene rubber.

These synthetic materials enhance durability, flexibility, and resistance to wear, making tyres a significant contributor to microplastic pollution over time.
