Microplastics are small pieces of plastic that are found in the environment. They are defined as plastic particles less than 0.2 inches (5 mm) in diameter health
They are either produced as small plastics, such as microbeads added to toothpaste and exfoliants. Or are created when larger plastics are broken down in the environment สมัคร UFABET
Microplastics are common in oceans, rivers and soil and are often consumed by animals.
A number of studies in the 1970s began investigating the levels of microplastics in the oceans. And found high levels in the Atlantic Ocean off the US coast.
These days, due to the world’s increasing use of plastic. There is much more plastic in rivers and oceans. An estimated 8.8 million tons (8 million metric tonnes) of plastic waste enter the ocean every year.
A whopping 276,000 tons (250,000 metric tonnes) of this plastic is currently floating at sea. While the rest has likely sunk or washed ashore.
Summary
Microplastics are small pieces of plastic less than 0.2 inches (5 mm) in diameter. They are found all over the world in rivers, oceans, soil and other environments.
Evidence from test-tube and animal studies suggests that microplastics may be bad for health. However, very few studies examining the effects of microplastics in humans currently exist.
