First of all, don’t freak out. I am not trying to “scare monger” but when I read the science on this topic, I was quite concerned (for myself as well as for you). So I felt that I needed to research this some more, and share with you.
I do hope you find the information and the suggestions useful for your workplace, and at home.

Executive Summary
Microplastics are increasingly being recognised as a public health concern. While traditionally associated with environmental pollution, new evidence highlights their direct impact on human health—especially in everyday environments like the workplace and at home.
This whitepaper outlines key findings from recent scientific research, explains the sources and risks of microplastic exposure, and provides actionable strategies for businesses to mitigate this emerging threat.
Key Takeaways
- Microplastics are found in food, water, air, and common workplace materials.
- These particles can accumulate in organs, contributing to diseases including Alzheimer’s, cardiovascular disorders, and hormonal imbalances.
- New research links microplastics to antibiotic resistance—especially in high-density environments. (eeek!)
- Businesses should take steps to assess, reduce, and manage microplastic exposure for both compliance and employee wellbeing.
What Are Microplastics?
Microplastics are plastic fragments smaller than 5mm. They originate from the breakdown of larger plastic items or are manufactured for use in products like food & drink containers, clothing, cosmetics and cleaning agents. In workplaces, common sources include air-conditioning systems, plastic packaging, synthetic uniforms, food containers, bottled water, and even office furniture.
Health Implications
Recent studies reveal that microplastics:
- Embed in human tissues—including lungs, liver, kidneys, and brain.
- Disrupt hormones, affect fertility, and suppress immune function.
- Are linked to neurodegenerative diseases and cardiovascular problems.
A separate, alarming study from Boston University shows that microplastics strengthen bacterial resistance to antibiotics. When bacteria grow on microplastic surfaces, they form dense biofilms that are hard to penetrate—turning common infections into serious medical threats.
Why Businesses Should Act
From office settings to industrial sites and at home, microplastic exposure is becoming a long-term health hazard. Businesses are responsible for identifying and controlling such risks under general health and safety obligations. Ignoring this issue could affect employee wellbeing, increase liability, and damage your ESG standing.
Practical Strategies for Employers
1. Assess Environmental Exposure
- Audit indoor air quality and install HEPA filtration systems.
- Identify and replace high-risk materials (black plastics, thermal receipts)
Black plastics are often made from recycled electronics and are full of chemicals like flame-retardants, which are known to be cancer-causing, endocrine-disrupting, and terrible for neurological health. (Source: Dr. Rhonda Patrick, Found My Fitness Podcast)
2. Improve Procurement Practices
- Choose suppliers using BPA-free, plastic-free packaging.
- Avoid synthetic PPE and uniforms when possible.
3. Encourage Safe Habits
- Educate staff on risks of heating food in plastic (especially black plastic) or using plastic bottled water.
- Promote use of stainless steel or glass drinkware.
4. Enhance Workplace Nutrition
- Offer or subsidise fresh, whole food options (avoiding packaged foods).
- Minimise ultra-processed food in vending and catering services.
5. Promote Physical Activity
Regular exercise not only boosts overall health but also enhances detox pathways, reducing the impact of environmental toxins like microplastics (more on this, in another article).
Conclusion
Microplastics are no longer just an ocean pollution problem. They are a growing health risk that requires urgent attention from employers. By adopting targeted strategies to reduce exposure, businesses can improve employee health, reduce liability, and position themselves as leaders in health, safety, and sustainability.
