Tiny particles of plastic, called microplastics, have now been detected in human blood. Yikes! We all know that plastic pollution is a serious problem in the environment, but recent research has been finding it in our food, in the air, in water, in rain, our organs (including our lungs and brain), human placentas, and now in our blood.

The most widely found microplastic particles in the blood were polyethylene terephthalate (PET) (commonly used in disposable water bottles), and polystyrene (PS), which is used for food packaging and polystyrene foam.

The big question is: What are microplastics doing to us, if anything?

The first studies are finding that microplastics are causing inflammation and damage to cells (not good), and are building up in us, but we don't really know much at all. Will it increase the risk of cancer? Scientists are also concerned over the chemicals in the microplastics. For example, if there are endocrine disrupting chemicals in the microplastics, then what effect (if any) are they having on us?

But... plastic production is increasing every year, so we can expect to be exposed to more plastic over time, which means more will get into us and the environment. And the particles will build up.

You may wonder why there are so many little plastic particles out there - it's because plastic breaks apart over time. Even when we do laundry - there are little plastic particles released into the drain water from synthetic fabrics. When we drink from plastic water bottles, little plastic particles released from the bottles are ingested by us. And yes, water bottles are a big source of microplastics ingested by us - up to an additional 90,000 microplastics per year!

Bottom line: try to cut back on your use of plastic, which means buying less of plastic goods - for example, in beverage containers (opt for glass bottles instead), in furniture and toys, in our homes (wood or tile instead of vinyl as much as possible). Avoid drinking from plastic water bottles.

From Smithsonian: Microplastics Detected in Human Blood in New Study

Microplastics, or tiny plastic particles, are ubiquitous pollutants found almost everywhere on earth. Scientists have detected microplastics near the peak of Mount Everest, in the Mariana Trench and even in baby poop. But researchers have now found a new vessel for microplastics: human blood. ...continue reading "Microplastics Are Found In Human Blood"
