Q. Which of the following terms associated with the plastic pollution have been correctly defined?
1. Plastiglomerate: It is formed when plastic trash melts and fuses together with natural materials as sand and basalt.
2. Plastisphere: It is a term used to refer to ecosystems that have evolved to live in human-made plastic environments.
3. Microdebsis: Plastic debris when it is larger than 20 mm.
Select the correct answer using the codes given below:
Explanation: Plastisphere is a term used to refer to ecosystems that have evolved to live in human-made plastic environments. Plastic that has made its way into marine habitats has been found to host various microorganisms.
Microdebris are plastic pieces between 2 mm and 5 mm in size. Plastic debris that starts off as meso- or macrodebris can become microdebris through degradation and collisions that break it down into smaller pieces.
Plastic debris is categorized as macrodebris when it is larger than 20 mm. These include items such as plastic grocery bags.
Plastiglomerate is a term that was proposed by Patricia Corcoran, Charles J. Moore and Kelly Jazvac for a stone that contains mixtures of sedimentary grains, and other natural debris (e.g. shells, wood) that is held together by hardened molten plastic It has been considered a potential marker of the Anthropocene, an informal epoch of the Quaternary proposed by some social scientists, environmentalists, and geologists.
