[1] [2] These microplastics are made primarily from polyethylene, polypropylene, polystyrene, polyvinyl chloride, and other plastics or synthetic resins. [3] Nurdles are the building block, via plastic extrusion or injection molding, for items for everyday life including plastic water bottles, containers, and bags. [4] An example of nurdles
Plastic "nurdle" pellets on a beach in southwest France, 2011. Plastic pellet pollution is a type of marine debris originating from the plastic particles that are universally used to manufacture large-scale plastics. In the context of plastic pollution, these pre-production plastic pellets are commonly known as 'nurdles'. [1]
Plastic degradation in marine bacteria describes when certain pelagic bacteria break down polymers and use them as a primary source of carbon for energy. Polymers such as polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET) are incredibly useful for their durability and relatively low cost of production, however it is their persistence and difficulty to be properly ...
By using data on surface plastic concentration (pieces of plastic per km 2) from 1972 to 1985 (n=60) and 2002–2012 (n=457) within the same plastic accumulation zone, the study found the mean plastic concentration increase between the two sets of data, including a 10-fold increase of 18,160 to 189,800 pieces of plastic per km 2.

The South Pacific garbage patch is an area of ocean with increased levels of marine debris and plastic particle pollution, within the ocean's pelagic zone. This area is in the South Pacific Gyre , which itself spans from waters east of Australia to the South American continent, as far north as the Equator , and south until reaching the ...
