Microplastics: Common Sources and Practical Ways to Reduce Exposure

Microplastics have been detected in water, food, air, dust and the wider environment. Researchers have also reported plastic particles in human samples, although important questions remain about exposure levels, measurement methods and possible long-term health effects.

It is therefore more accurate to focus on practical ways to reduce unnecessary exposure rather than promise that microplastics can be completely avoided or that reducing exposure will produce a specific health benefit.

What Are Microplastics?

Microplastics are plastic particles generally smaller than 5 mm. They can originate from the breakdown of larger plastic items, industrial processes, tyre wear, packaging and synthetic textiles.

1. Drinking Water

Microplastics have been detected in both bottled and tap water. Concentrations vary considerably between studies and locations.

Practical choices include using reusable glass or stainless-steel bottles and avoiding unnecessary heating or prolonged storage of drinks in plastic containers. Water filtration can reduce some particles, but performance depends on the filtration technology and particle size.

2. Food and Food Contact Materials

Plastic particles have been reported in various foods and beverages. Packaging and food preparation can also create opportunities for contact with plastics.

Simple precautions include avoiding heating food in unsuitable plastic containers, following manufacturer instructions and using glass, ceramic or stainless steel where practical.

3. Synthetic Textiles

Polyester, nylon, acrylic and other synthetic textiles can shed plastic microfibres during manufacturing, wear and washing. These fibres can enter wastewater, indoor dust and the wider environment.

Choosing natural fibres can reduce reliance on plastic-based textile fibres. When synthetic garments are necessary, washing them less frequently when appropriate, using gentler cycles and considering effective microfibre-capture solutions may help reduce shedding.

4. Indoor Dust and Air

Indoor environments contain fibres and particles from textiles, furnishings and many other sources. Regular cleaning and ventilation can reduce overall dust accumulation, although they cannot eliminate microplastic exposure.

5. A Practical, Proportionate Approach

Microplastics are widespread, so complete avoidance is unrealistic. Reasonable steps include reducing unnecessary single-use plastics, avoiding inappropriate heating of plastics, choosing durable products and favouring non-plastic materials when they meet the same need.

What Science Still Does Not Know

The presence of microplastics in the environment and in human samples is an active field of research. Detection does not by itself establish the size of a health risk. Researchers continue to investigate exposure pathways, particle characteristics and potential biological effects.

Conclusion

Reducing unnecessary contact with plastics can be a sensible precaution, but it should not be presented as a medical treatment or guarantee of better health. At ERVERTE Paris, our interest in natural fibres is primarily connected to material choice, durability and reducing reliance on plastic-based textiles.
