Q. Consider the following:
I. Cigarette butts
II. Eyeglass lenses

- II. Eyeglass lenses: Commonly made from plastics like CR-39 and polycarbonate for lightness and impact resistance.
- III. Car tyres: Blend of natural rubber and synthetic rubber (plastic polymers such as SBR, polybutadiene), a major source of microplastics.
