Scientists discover microplastics in aquatic life, human blood, breast milk

In recent years, scientists have discovered increasing amounts plastic particles in deep oceans, Arctic snow, drinking water, and even breast milk.

In recent years, scientists have discovered increasing amounts plastic particles in deep oceans, Arctic snow, drinking water, and even breast milk.

How’s that possible?

The answer lies in nearly 350 million tons of plastic being produced globally each year, and about 250,000 tons of plastic littering our oceans.

Precipitation cycles carry microplastics through the air, scattering them across the planet and situating them within natural food chains that comprise ecosystems. As a result, these durable particles have ended up just about everywhere, and scientists believe they’re not going away anytime soon.

Beyond deriving from plastic debris that has degraded into smaller pieces, microplastics have also been prominent in health and beauty products, such as certain cleansers and toothpastes. Microbeads, a type of microplastic, are a form of polyethylene plastic that easily passes through water filtration systems eventually posing a risk to aquatic life.

A recent study led by Stanford University researchers determined that blue whales consume up to 10 million pieces of microplastic daily, largely through the prey that they eat.

Environment International reported that traces of microplastics were discovered in 80 per cent of blood samples taken from 22 anonymized, healthy humans.
