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 ...
Specifically, the study examined the edible tissue of fish often fished along the Oregon coast or sold in the state's markets: black rockfish, lingcod, Chinook salmon, Pacific herring, Pacific ...
These microplastics are frequently consumed by marine organisms at the base of the food chain, like plankton and fish larvae, which leads to a concentration of ingested plastic up the food chain. Plastics are produced with toxic chemicals, so these toxic substances enter the marine food chain, including the fish that some humans eat. [39]
A study in 2023 tested some fish species and found that “about 80% of the MPs detected were fibrous in shape and were made of polyethylene (25%), polyester (20%), and polyamide (10%). Most microplastic particles observed were black (61%) or blue (27%) in color.” [ 162 ]
Plastivores are "organisms that use plastic as their primary carbon and energy source". [3] This does not necessarily mean being able to fulfill all biological needs from plastic alone.
In 1996, Monsanto discovered a method of producing one of the two polymers in plants and acquired Biopol from Zeneca, a spinout of ICI, as a result of the potential for cheaper production. [ 11 ] As a result of the steep increase in oil prices in the early 2000s (to nearly $140/barrel US$ in 2008), the plastic-production industry finally sought ...
A deadly pufferfish hospitalized an entire family who unintentionally consumed the poisonous fish for dinner. According to Brazil's Globo News, eleven members of the Souza family ate a pufferfish ...
Degraded plastic waste can directly affect humans through direct consumption (i.e. in tap water), indirect consumption (by eating plants and animals), and disruption of various hormonal mechanisms. [12] As of 2019, 368 million tonnes of plastic is produced each year; 51% in Asia, where China is the world's largest producer. [13]
