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

Dec. 5, 2022

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.
