Do you like eating microplastics? We bet you don't! Well, your adored polyester hoodie is likely contributing to the global plastic pollution crisis.

Considering the fabric reeks of tacky mundanity, it's no wonder camp filmmaker John Waters (Pink Flamingos) named his 1981 satire flick about an in-over-her-head suburban housewife Polyester. And though it's associated with cheapness, most of us — from all points on the financial spectrum — own at least three items of clothing possessing polyester shells, blends, or linings. So, what is the common textile, really?
According to textile supplier Apex Mills, polyethylene terephthalate is a synthetic fiber made by mixing ethylene glycol with terephthalic acid. It's so popular because its' durable, moisture and wrinkle resistant, and moldable.
Polyester is an oil-based plastic and isn't considered biodegradable, so it's hard on the environment. But how does that discounted polyester dress affect your health; is it bad for you? Could budget-friendly fashion be ... deadly? Without fearmongering, let's talk facts.
Here at Green Matters, we typically associate plastic with, well, evil. To put things in perspective, environmental charity Surfers Against Sewage relayed that 12 million tons of plastic is discarded into the ocean annually, 2.5 tons of carbon dioxide is generated when producing 1 ton of plastic, and about 1 in 3 fish captured for human consumption currently contains plastic. Plastic pollution is a major contributor to the climate crisis.
When it comes to clothing, many brands offer recycled polyester pieces, which is a kinder alternative to using virgin plastics.
Still, when polyester clothing is produced, worn, and washed, it sheds microfibers — aka microplastics — which end up in our waterways and oceans. According to the Council of Fashion Designers of America, the washing and disposal of polyester also pollutes the water via the release of heavy metals and toxic chemicals.
Organic clothing company Opok wrote that "a single synthetic garment can release up to 1.7 grams of microfibers per wash." Shockingly, an estimated 5.25 trillion macro and microplastics currently float in the ocean. Big yikes.
And while we can't help but giggle at satirical Gen Z bumper stickers that say "I eat microplastics," there's a sad truth to this. According to The BBC, "microplastics have infiltrated every part of the planet," including the land, water (yes, drinking water), and air. Therefore, microplastics are a sneaky ingredient in the food we eat.
The nonprofit Environmental Working Group (EWG) discovered "sewage sludge has contaminated almost 20 million acres of U.S. cropland with [PFAS], often called 'forever chemicals,'" as reported by the publication. Synthetic fabrics like polyester and nylon may contain PFAS, which don't typically break down.
From there, sewage sludge (a wastewater byproduct) is routinely used as an organic fertilizer in the U.S. and Europe. Why? It's both expensive to eliminate and rich in nutrients.
In short, sludge contaminates farmland and microplastics end up in food.

Willie Peijnenburg, an environmental toxicology and biodiversity professor at Leiden University in the Netherlands, found that crops absorb nanoplastic particles (which are even smaller than microplastics) via cracks in their roots. While leafy veggies like cabbage and lettuce likely contain small amounts of plastic particles, Peijnenburg warned that root vegetables contain higher levels of plastic particles.
Evidence has shown that chemicals added during the production of plastics can mess with the endocrine system, affecting hormones in the process. As detailed by The BBC, these nasty chemicals have also been linked to cancer, heart disease, and fetal growth restriction.
The fetal development disruption research was specifically connected to BPA (bisphenol A) exposure, as mentioned in a 2022 scholarly article. However, it's important to note that the Center for Environmental Health's study only found BPA in "polyester-based clothing with spandex." Because of this, the CEH recommends removing synthetic activewear and socks directly after exercising.

As for microplastics, researchers at the University of Hull in the U.K. found that ingesting high amounts of microplastics can cause cell damage and, in turn, inflammation and allergic reactions. The Caco-2 cell line was the most susceptible to damage.
