Marine plastic pollution. The pathway by which plastics enters the world's oceans. Marine plastic pollution 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 ...
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] These microplastics are created separately from the user plastics they are ...
Microplastics are fragments of any type of plastic less than 5 mm (0.20 in) in length, [1] according to the U.S. National Oceanic and Atmospheric Administration (NOAA) [2][3] and the European Chemicals Agency. [4] They cause pollution by entering natural ecosystems from a variety of sources, including cosmetics, clothing, food packaging, and ...
Dr. Tianxi Yang and his team have created a small, portable device that can accurately measure microplastics in water samples within minutes. The innovative tool consists of a 3D-printed box ...
e. Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms.
More recent research has found that typical water bottles have far higher levels: 240,000 particles per liter on average, taking into account smaller fragments known as "nanoplastics." The ...
Microplastics effects on human health are of growing concern and an area of research. The tiny particles known as microplastics (MPs), have been found in various environmental and biological matrices, including air, water, food, and human tissues. Microplastics, defined as plastic fragments smaller than 5 mm, and even smaller particles such as ...
The plastisphere is a human-made ecosystem consisting of organisms able to live on plastic waste. Plastic marine debris, most notably microplastics, accumulates in aquatic environments and serves as a habitat for various types of microorganisms, including bacteria and fungi. [1][2] As of 2022, an estimated 51 trillion microplastics are floating ...
