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] Plastics are inexpensive and durable ...
They cause pollution by entering natural ecosystems from a variety of sources, including cosmetics, clothing, food packaging, and industrial processes. [1] [5] The term microplastics is used to differentiate from larger, non-microscopic plastic waste. Two classifications of microplastics are currently recognized.
Microplastics, defined as plastic fragments smaller than 5 mm, and even smaller particles such as nanoplastics (NP), particles smaller than 1000 nm in diameter (0.001 mm or 1 μm), have raised concerns impacting human health. [1][2] The pervasive presence of plastics in our environment has raised concerns about their long-term impacts on human ...
That is a key point that both Gaver and McKinney stress: recycling should not be the number-one option when it comes to attacking the problem of microplastics. “Once you get to recycling, every ...
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 ...
Microplastics are turning up in unusual places increasingly often as they filter into nearly every facet of life on Earth. They’ve been discovered in drinking water, food, air and even in blood.
Particulate pollution is observed around the globe in varying sizes and compositions and is the focus of many epidemiological studies. Particulate matter (PM) is generally classified into two main size categories: PM 10 and PM 2.5. PM 10, also known as coarse particulate matter, consists of particles 10 micrometers (μm) and smaller, while PM 2 ...
Plastics accounts for 80% of waste dispersed in the marine and coastal environment of the Mediterranean Sea. [24] Recent studies focus on the types of plastics found and primarily on the issue of microplastics, both at a global but also at a regional level, as in the case of the Mediterranean Sea, which was identified as a "target hotspot of the world" due to its amounts of microplastics ...
