Estimates of the total number and weight of plastic across five ocean gyre plastic concentration zones are of the order of 5.25 trillion particles weighing almost 300,000 tons. [32] The reduction in size of plastic particles to the millimeter and micro-scales allow plastic to settle within deep sea sediments, with perhaps four times as much ...
The United States National Academy of Sciences estimated in 2022 that the worldwide entry of plastic into the ocean was 8 million metric tons of plastic per year. [63] A 2021 study by The Ocean Cleanup estimated that rivers convey between 0.8 and 2.7 million metric tons of plastic into the ocean, and ranked these river's countries. The top ten ...
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 ...
Plastic pollution in the ocean is a type of marine pollution by plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean.
The first 45-day expedition removed 103 short tons (93 t; 206,000 lb) of plastic [73] and the second expedition removed 67 short tons (61 t) of plastic from the garbage patch. [74] In 2022, over the course of 2 summer expeditions, Ocean Voyages Institute removed 148 short tons (134 t; 296,000 lb) of plastic ghostnets, consumer items and mixed ...
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 ...
A post shared on social media purportedly shows a video of a helicopter lifting water out of the Pacific Ocean to fight the current fires in Los Angeles. Verdict: False The video dates back to 2019.
A more recent concern in microplastic pollution is the use of plastic films in agriculture. 7.4 million tons of plastic film are used each year to increase food production. [22] Scientists have found that microbial biofilms can form within 7–14 days on plastic film surfaces, and have the ability to alter the chemical properties of the soil ...
