Executive Summary Plastic production has skyrocketed over the past five decades, generating millions of tons of waste annually. A large portion of this waste eventually fragments into microplastics — particles smaller than 5 mm — that now pervade air, soil, water, and even the human body. Mounting evidence indicates that microplastics contribute to chronic inflammation, endocrine disruption, and reproductive harm. While a complete detox methodology is not yet available, lifestyle interventions, dietary strategies, and systemic policy changes can reduce exposure and mitigate harm. This white paper provides: An overview of microplastics and their environmental impact Current understanding of human health risks Emerging strategies for minimizing exposure A roadmap for collective action and policy solutions 1. Introduction: Plastic Dependency and the Rise of Microplastics Modern society relies heavily on plastics for packaging, textiles, electronics, and consumer goods. Global plastic pro...

Scientists have found that tea bags contain millions of micro- and nanoplastics (MNPLs) that may be entering your body every time you drink tea. Research has shown that some plastics are more readily absorbed by cells in the digestive system and may cause DNA damage. Tea bags with an irregular surface may release more microplastic particles. Tea Bags Leach Plastic Particles A study published in the November 2024 issue of Chemosphere examined three types of commercial tea bags made from either nylon, polypropylene, or cellulose (a plant-based material). The researchers simulated typical tea use by immersing and stirring tea bags in water. They found that all three tea bag materials released microparticles during simulated tea preparation, with polypropylene (PP) releasing the most and nylon releasing the least. Tea is the second-most-consumed beverage globally, and each plastic tea bag steeped at brewing temperature releases around 11.6 billion microplastics and 3.1 billion nanoplast...

Most people enjoy eating seafood regularly or taking a relaxing, warm bath. While these seem harmless, research shows that they now come with an unseen invader — microplastics. These tiny plastic particles, often smaller than a grain of sand, are increasingly pervasive in our environment. In fact, they’re now in your brain and other organs. A 2025 study published in Science Advances explored a mechanism by which microplastics directly impact brain function. The study used advanced imaging techniques to observe, in real-time, the effects of microplastics on the brains of mice. Not only were microplastics present in the brain, but they actively disrupted normal brain function by physically blocking blood flow within the brain's delicate network of vessels. Plastic Is Everywhere, and It’s Also in Your Brain In a preprint study published in Research Square, researchers sought to find out the amount of micro- and nanoplastics (MNPs) currently embedded in the human body. For their ex...
