"Microplastic particles" refer to tiny pieces of plastic that are often less than 5 millimeters in size. These particles come from the breakdown of larger plastic items, such as bottles or bags, as well as from microbeads used in personal care products. They are a concern because they can be harmful if consumed by wildlife or humans, and they can also contaminate the environment.

According to news sources, such as the BBC, researchers at State University of New York in Fredonia found
microplastic particles in nearly all of 250 bottled waters bought in nine different countries.

In a scientific paper released June 12 in the international journal Archives of Environmental Contamination and Toxicology, Dr. Ross and his co-authors, Jean - Pierre Desforges and Moira Galbraith, report
on microplastic particles found in two key species of zooplankton found in the Northeast Pacific Ocean: copepods and euphausiids.
The authors estimate using findings in zooplankton that juvenile salmon in the Strait of Georgia may be ingesting two to seven
microplastic particles per day, and returning adult salmon are ingesting up to 91 particles per day.
According to a study commissioned by Orb Media, a global consortium of journalists, samples from 93 per cent of 259 bottles
contained microplastic particles — an average of 10 particles wider than 100 micrometres, or roughly the width of a human hair, per litre.
So far, however, there has been no reliable knowledge as to
whether microplastic particles in aquatic ecosystems promote the development of special bacterial communities or even the spread of pathogens.
A recent study within the project MikrOMIK * headed by the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) has now for the first time systematically investigated whether bacterial biofilms on
microplastic particles differ from those on natural materials and how various environmental factors such as salinity or nutrients influence the community composition.
Using this method, they estimate a humpback, which is a baleen whale, could ingest more than 300,000
microplastic particles per day.
The 2017 United Nations Clean Seas Campaign estimated that there are 51 trillion
microplastic particles in the ocean today — 500 times more than the number of stars in our galaxy.
These microplastic particles now account for 90 % of the new pollutants found in Lake Erie.
If adults were to consume sea salt at the recommended nutritional level for the seasoning, they could potentially ingest 1,000
microplastic particles every year from that source.
Microplastic particles may taint some bottled water, but the ecological cost of bottles is a better reason to turn on the tap instead
The UN writes, «As many as 51 trillion
microplastic particles — 500 times more than stars in our galaxy — litter our seas, seriously threatening marine wildlife.»
Latest study conducted by Plymouth University researchers has found that everyday cosmetic products, such as facial soaps, toothpastes and exfoliants, contain around 100,000
microplastic particles that often end up as pollutants in oceans and rivers.
