Every day, we come into contact with microscopic plastic particles that are invisible to the naked eye. They are becoming ever-present in the air we breathe, the water we drink, and the food we eat. These microplastics have become one of the most pervasive and invasive environmental health challenges of our time. Found everywhere from the deepest oceans to Arctic ice, microplastics are now even detected in human blood and lungs.

Understanding where they come from and how to reduce exposure is key to protecting both the health of humanity and the planet.

1. What Are Microplastics?

Microplastics are tiny plastic fragments less than 5 millimetres in size. They can be divided into two main categories:

  • Primary microplastics – intentionally manufactured small plastics such as microbeads used in exfoliating scrubs, toothpaste, or cosmetics.
  • Secondary microplastics – fragments created when larger plastic products (like bottles, synthetic clothing, or packaging) break down over time due to sunlight, friction, or water.

These particles can contain toxic additives — such as phthalates, bisphenols (like BPA), and flame retardants — that disrupt the endocrine system, cause skin irritation, and harm aquatic and soil ecosystems.

2. The Growing Problem of Microplastic Exposure

Microplastics are now ubiquitous in our environment. Studies have found them in tap water, bottled water, in indoor air and household dust (especially from synthetic fabrics and carpets), and even in aquatic animals and table salt. They have also been detected in the human bloodstream, lungs, and placenta.

Long-term exposure may contribute to respiratory irritation, inflammation, oxidative stress, and other chronic health effects. For people with Multiple Chemical Sensitivities (MCS), these exposures can exacerbate symptoms due to the presence of chemical residues and additives. As these chemicals are extremely difficult to detect, vulnerable individuals may be exposed to microplastics with no recognition.

3. Do’s and Don’ts to Reduce Microplastic Exposure

Do:

  • Choose natural fabrics such as cotton, hemp, linen, or wool instead of synthetic fibers like polyester, nylon, or acrylic. By doing so, you will be making conscious consumer choices, and not contributing to the growing microplastic epidemic.
  • Wash clothes in cold water and use a microfiber filter bag (e.g., Guppyfriend) or a washing machine filter to capture microfibers.
  • Drink filtered tap water using carbon block or reverse osmosis filters such as Aquaovo or TAPP Water.
  • Use glass, stainless steel, or ceramic containers instead of plastic food packaging.
  • Vacuum regularly with a HEPA filter vacuum to reduce airborne microplastics and dust particles.
  • Support policies and companies that ban or phase out microbeads and reduce single-use plastics.


Don’t:

  • Buy synthetic clothing and fleece fabrics that shed microfibers during washing.
  • Heat or microwave food in plastic containers.
  • Encourage the use of single-use plastics, including straws, utensils, and take-out packaging.
  • Use personal care products containing “polyethylene” or “polypropylene” — these are microplastics.
  • Buy glitter, as it is often made of plastic and contributes to microplastic pollution.

4. Avoiding Microplastics in the Home

Microplastics accumulate indoors through synthetic fabrics, cleaning products, and dust. To reduce them:

  • Replace synthetic sponges with natural cellulose or loofah alternatives.
  • Choose wood, bamboo, or metal brushes and utensils instead of plastic ones.
  • Use natural cleaning cloths (cotton, hemp, linen) instead of microfiber cloths.
  • Replace synthetic carpets and rugs with natural fiber options such as wool or jute.
  • Avoid household paints or coatings containing plastic polymers; opt for natural, water-based paints free from acrylics and vinyl.

5. Microplastics on the Shore and in Waterways

Beaches and coastal areas are hotspots for microplastic pollution, as waves and UV light break down waste into microscopic fragments. These particles harm marine life — often ingested by fish and birds — and eventually enter the human food chain.

How to help:

  • Participate in local beach clean-ups organized by groups such as Ocean Wise or Surfrider Foundation Europe.
  • Avoid releasing synthetic microfibers into the water by washing synthetics less often and using filters.
  • Use reef-safe, microplastic-free sunscreens such as Green Beaver or Laboratoires de Biarritz.
  • Choose biodegradable outdoor gear free from synthetic coatings.

6. Microplastics in Clothing and Laundry

Synthetic clothing is one of the largest sources of microplastic pollution. Each wash can release thousands of fibers into wastewater systems.

Better choices include:

  • Natural fabrics such as organic cotton, hemp, and merino wool.
  • PFAS- and plastic-free waterproof clothing from brands such as Vaude, Tentree, and Fjällräven.
  • Install washing machine filters such as PlanetCare to capture fibers before they reach waterways.

7. Microplastics in Food and Packaging

Microplastics enter the food chain through contaminated packaging and cooking materials.
To minimize exposure:

  • Store and cook food in glass, ceramic, or stainless steel containers.
  • Avoid tea bags made of nylon or plastic — choose loose-leaf tea with a stainless steel infuser.
  • Buy fresh or bulk food instead of pre-packaged options wrapped in plastic.
  • Use beeswax wraps instead of cling film — such as Abeego.
