Which polymer, commonly used in single-use bags, is a major component of buoyant marine microplastics?

Options:

Polyethylene (PE)
Polyvinyl chloride (PVC)
Polyethylene terephthalate (PET)
Nylon (polyamide)

Correct answer: Polyethylene (PE)

Explanation: Polyethylene (PE) is widely used for bags and packaging and is a dominant buoyant marine plastic; its density (~0.91–0.97 g/cm³) is usually lower than seawater, allowing it to float and fragment into microplastics.
