We know that plastic is an environmental hazard. And the use of plastic among various products like bottles, bags and other articles across the globe.
Plastic is not biodegradable. It is a hazardous waste on the earth. Over the period of time, this material disintegrates into smaller pieces and these smaller particles are dangerous for marine life.
Still, it is not clear that microplastics are harmful to human health.
What are microplastics?
Over time, plastic disintegrates into smaller or tiny pieces which are called microplastics.
Size of the tiny piece of the microplastics generally ranges from 5 millimeters down to 100 nanometers in diameter.
According to their size, they are subcategorized in primary microplastics and secondary microplastics.
Primary microplastics are microbeads, which are generally used in face wash, cosmetics, and scrubs as polyethylene. The US has banned these microbeads under Microbead-Free Water Act of 2015.
Secondary microplastics are larger pieces of the plastic which breaks down into tiny pieces over time.
Microplastics in the food
Microplastics are so small that they easily escape from water filtration and make their way to rivers and oceans. These microplastic remains in the ocean forever.
In rivers and oceans, fish and other marine animals eat them and microplastics are so bad that these species die due to the toxic effect of the microplastics.
One studies also show us that, many brands sea salt contain these microplastics in more or less proportion into them.
And most important thing is that human eats both fish and salt, so finally microplastics ends up in the human body.
Are microplastics harmful to human?
All the major studies have shown that microplastics are found in the marine foods. However, it is still not clear that whether it has any harmful effect on the human body. (1)
Some researches show that microplastics are found in human lungs and it is due to its presence in the air. (2)
One of the chemicals found in the microplastics is Bisphenol A. This chemical has an adverse effect on reproductive hormones, specifically in women. (3)
Still, various researches are going on its impact on the human body.
