A 2017 study found indoor airborne microfiber concentrations between 1.0 and 60.0 microfibers per cubic meter (33% of which were found to be microplastics). [137] Another study looked at microplastic in the street dust of Tehran and found 2,649 particles of microplastic within 10 samples of street dust, with ranging samples concentrations from ...
Polypropylene is discovered by Giulio Natta with production starting in 1957 [1] 1954: Expanded polystyrene, used for building insulation, packaging, and cups, is invented by Dow Chemical. [1] 1957: The Italian firm Montecatini begins large-scale commercial production of isotactic polypropylene. 1960s
Researchers found microplastics in soil deposits more than seven meters (23 feet) underground, which were deposited in the first or second century CE and excavated in the 1980s, a team led by ...
Humans are exposed to toxic chemicals and microplastics at all stages in the plastics life cycle. The effects of microplastics on human health are a growing concern and an actively increasing area of research. Tiny particles known as microplastics (MPs), have been found in various environmental and biological matrices, including air, water ...
People with microplastics and nanoplastics in plaque lining a major blood vessel in their neck may have a higher risk of heart attack, stroke or death, new research suggests. Doctors found tiny ...

Of the 12 coral and sediment samples taken, all were found with an abundance of microplastics. [33] Rayon is not a plastic but was included in the study due to being a common synthetic material. It was found in all samples and comprised 56.9% of materials found, followed by polyester (53.4%), plastics (34.1%) and acrylic (12.4%). [ 33 ]
Microplastics are commonly found in soil. [ 9 ] [ 10 ] Techniques are under development to achieve reductions in soil microplastics via photodegradation , chemical extraction , or bioremediation . [ 11 ] [ 12 ] [ 13 ]
