Plasticrust
Plasticrusts are a new type of plastic pollution in the form of plastic debris, covering rocks in intertidal shorelines which vary in thickness and in color and are composed of polyethylene as determined by fourier-transform infrared spectroscopy (FTIR) analysis. They were first discovered on the South coast of the volcanic island of Madeira in the Atlantic Ocean in 2016 and have additionally been found on Giglio Island, Italy. They are considered a sub-type of plastiglomerate and could possibly have negative effects on surrounding fauna by entering the food web through consumption by Marine invertebrates, benthic invertebrates. Formation Plasticrusts are formed by waves smashing plastic debris against rugose rocks. A report concluded that “plasticrust abundance may depend on the local levels of nearshore plastic debris, wave exposure and tidal amplitude.” This was based on the abundance of plasticrusts compared to the other listed factors at each location where plasticrust w ...

Plastiglomerate
Plastiglomerate is a rock made of a mixture of sedimentary grains, and other natural debris (e.g. shells, wood) that is held together by 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. Origin Plastiglomerates form along shorelines where natural sedimentary grains and organic debris are agglutinated by melted plastic. They can be created during campfire burning, as has been reported from Kamilo Beach on the island of Hawaii, or during hot weather, as is the case on Trindade Island. Depositional environment Plastiglomerate could potentially form a marker horizon of human pollution on the geologic record. and may survive as future fossils. Plastiglomerate may also conceivably form in plastic pollution, plastic-polluted regions affected by lava flows or forest fires. They have been found on the surface as well as beneath the sand. This suggests that plasti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
