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 ...
The first industrially practical polyethylene synthesis is discovered by Eric Fawcett and Reginald Gibson at the Imperial Chemical Industries (ICI) works in Northwich, England. [10] 1935: Nylon is invented and patented by DuPont. [6] 1938: Nylon is first used for bristles in toothbrushes.
In the 1960s microplastics were observed in the guts of seabirds, and since then have been found in increasing concentrations. [57] The long-term effects of plastics in the food chain are poorly understood.
Woodruff, who has studied the effect of some chemicals found in plastics on human health, reproduction, and development for two decades, first started looking into microplastics in 2021.
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 ...
Specifically, the peer-reviewed study found microplastics — "tiny particles that shed from clothing, packaging and other plastic products" — in 180 out of 182 samples of seafood that were ...
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 ...
