Plastic pollution is the accumulation of plastic objects and particles (e.g. plastic bottles, bags and microbeads) in the Earth's environment that adversely affects humans, wildlife and their habitat. [1] [2] Plastics that act as pollutants are categorized by size into micro-, meso-, or macro debris. [3]
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 which floats on, or is suspended in the ocean. Eighty percent of marine debris is plastic.
Nurdles can disrupt many ecosystems, as some birds and fish may confuse these plastic pieces for their food and can end up starving because of how much plastic they have eaten. Nurdles can adsorb toxins and other harmful chemicals, known as persistent organic pollutants (POPs), that can be eaten by fish, which can poison them or get caught for ...
The new study also found that bacteria removed more plastic pollution in lakes that had fewer unique natural carbon compounds. Researchers say the results will help to prioritise lakes where the ...
A garbage patch is a gyre of marine debris particles caused by the effects of ocean currents and increasing plastic pollution by human populations. These human-caused collections of plastic and other debris are responsible for ecosystem and environmental problems that affect marine life, contaminate oceans with toxic chemicals, and contribute ...
Plastic pollution, specifically microplastics, are a major contributor of PCBs into the biosphere and especially into marine environments. PCBs concentrate in marine environments because freshwater systems, like rivers, act as a bridge for plastic pollution to be transported from terrestrial environments into marine environments. [ 45 ]
A small study published Wednesday in the New England Journal of Medicine raises more questions than it answers about how these bits — microplastics and the smaller nanoplastics — might affect ...
While visible pollution caused by larger plastic items is well-documented, the hidden threat posed by nanoplastics remains under-explored. These particles originate from the degradation of larger plastics and are now found in various environmental matrices, including water, soil, and air.
