Can Reducing Microplastics in Our Lives Be Achieved? Expert Opinions Explored

In the never-ending tug-of-war with toxic gunk, microplastics take center stage as this pesky pollutant finds its way into our lives in the most unexpected places, one of the latest being your humble cup of tea. A recent study reveals that brewing tea with polymer-based teabags triggers significant microplastic release [1]. Is it any wonder we're all becoming increasingly alarmed about what these teensy particles could be doing to our health?

But fear not, for the answer to "what can I do?" isn't quite as drastic as tossing your entire household onto the curb for a plastic-free redo...that might actually be impossible and rather expensive. At least, that's what our experts insist. Here are some tips to help you cut back on your microplastic exposure without ending up in the poorhouse:

Beast Mode on Microplastics: A Primer

Microplastics, says Dr. Christy Tyler, PhD, a professor of environmental science at the Rochester Institute of Technology, refer to "any kind of plastic that's less than five millimeters" - smaller than a grain of rice [1]. Everything from clothing to consumer goods is at risk of containing these foes, including synthetic materials like spandex. Don't forget those pesky chemicals added to plastics to make them flame-retardant and more flexible! Any material starting with "poly-" is usually plastic-based and a potential microplastic culprit.

We find microplastics everywhere - in our environment, our stuff, our water sources, even in the Arctic, for crying out loud. These pesky particles can enter our bodies through ingestion, inhalation, or direct contact with the skin [2]. Yet, we're still scratching our heads about the exact amount that makes its way inside our bodies and the potential long-term effects it may have on our health [2]. Basically, we're clueless about what these microplastics are doing to our bodies. But there is a growing body of evidence suggesting nothing good.

Scientists believe that microplastics and their associated chemicals may provoke inflammation and oxidative stress - processes that can overstress and damage tissues, potentially leading to a host of diseases, such as heart disease, cancer, and diabetes [2]. A 2024 study co-authored by Dr. Tracey J. Woodruff, PhD, MPH of UCSF focuses on the possible impact of microplastics on reproductive, respiratory, and gastrointestinal health[2]. Researchers found evidence supporting negative effects on sperm quality, suppression of the immune system, and potential links to colon cancer [2]. While it's still early days in the world of microplastics research, these findings deserve our attention.

Microplastic Whack-a-Mole: What Experts Want You to Know

Before diving headfirst into zeroing out your microplastics exposure, experts offer the following sage advice:

1. Microplastics Aren't Entirely Avoidable: Remember the impossible zero-waste lifestyle for eliminating pollution at home? Well, microplastics are no exception. You can definitely cut back on your exposure, but absolute elimination is not in the cards.
2. Still a Lot to Learn: Experts themselves acknowledge the gaps in our knowledge. For example, we currently lack standardized methods for measuring microplastics [3]. This makes comparing studies challenging.
3. Let Your Lifestyle Habits Guide You: Identify where your exposure to microplastics is highest and focus your efforts there. For most people, this would likely be their kitchen. After all, food is a major source of microplastic contamination.
4. Make Changes Gradually: Don't feel overwhelmed by all the information on microplastics. Tackle one change at a time and implement it gradually. You'll be reducing your exposure while ensuring your sanity remains intact.

Microplastic Hotspots: Common Sources of Microplastics and Ways to Avoid Them

If you're curious about the primary offenders when it comes to microplastic exposure, focus your efforts on these problem areas:

The Kitchen

In a battle royale of microplastic sources, the kitchen emerges as the frontline. "I think food is the top tier," agrees Dr. Woodruff [1]. Here's why:

• Processed and fast food often contain harmful chemicals common in plastic like phthalates [2]. Cooking with plastic ware like pans, spatulas, and microwave meals ups your risk for exposure due to heat softening plastics and releasing chemicals [1].
• Wear-and-tear on kitchenware makes it more prone to shedding microplastic particles [1]. Consider replacing old plastic containers with glass, stainless steel, or silicone, as well as updating nonstick pans to stainless steel, cast iron, or ceramic options.
• Toss old plastic cutting boards and replace them with wooden options when possible.
• Finally, opt for wooden, silicone, or metal spoons and spatulas for cooking.

Other Household Items

• Limit your use of ultra-processed foods, focusing on whole, natural foods instead [1].
• Invest in a filter that has been tested by the National Sanitation Foundation for its ability to reduce microplastics, if you're concerned about tap water [1].
• Limit your use of single-use bottled water [1]. Use a refillable water bottle instead, preferably metal or glass.
• Order in less and use your own silverware instead of disposable options [1].
• Bring your own coffee cup or thermos when ordering coffee [1]. Many places will let you use your own mug or thermos.

Fabrics

The relationship between microplastics and fabrics, particularly fabrics that come into repeated contact with the skin, hasn't been extensively studied. However, research suggests that some chemicals in microplastics can cross the skin barrier [4]. If you're concerned about this route of exposure, consider favoring natural fabrics, such as cotton, linen, wool, and silk, when buying new items.

Personal Care Products

While not extensively studied, scientists do know that some of the chemicals in microplastics can cross the skin barrier [4]. Commonplace habits like washing hands, taking off shoes indoors, and using wet mops or microfiber cloths can help reduce microplastic accumulation in your home [4].

By tackling these areas, you'll be well on your way to minimizing your microplastic exposure. So grab your tea without worrying about the potential brewing disaster, and sip away, knowing you're doing your best to keep those pesky microplastics at bay!
