Microplastics are increasingly infiltrating human tissues, including the brain. An international study found microplastics in the olfactory bulbs of 8 out of 15 deceased individuals, marking the first detection in brain tissue. Researchers identified polypropylene as the most common polymer, with particle sizes ranging from 5.5 to 26.4 micrometers. The study suggests microplastics may reach the brain via the olfactory pathway, similar to air pollution particles. Despite health risks, plastic production has doubled in the last 20 years, highlighting ongoing reliance on plastics.

Global scientists and campaigners urge immediate action on plastic’s impact on human health, following a report revealing indoor environments as major microplastic pollution sources. Research led by Professor Thais Mauad and Dr. Luis Fernando Amato-Lourenco found microplastics in the olfactory bulb, suggesting the olfactory pathway as an entry route to the brain. They identified plastic fibers in 8 out of 15 brain samples from deceased Sao Paulo residents, with polypropylene being the most common. The study highlights the potential for smaller nanoplastics to enter cells and alter bodily functions, posing significant health risks.

Microplastics have been discovered in brain tissue above the nose, indicating a potential pathway for these particles to enter the brain, according to a study in JAMA Network Open. The most common types found were polypropylene, polyamide, nylon, and polyethylene vinyl acetate, used in various consumer products. Microplastics, less than 5mm in size, originate from the breakdown of items like bottles and packaging. They have been detected in multiple human organs, including blood, lungs, and the placenta. Efforts to curb microplastic pollution include an EU ban on microplastics in new products.

Scientists in Brazil discovered microplastics in the brain tissue of cadavers, specifically in the olfactory bulb, according to a study in JAMA Network Open. This finding adds to growing evidence of microplastics in various human organs and the bloodstream. Researchers examined olfactory bulb tissue from 15 cadavers, finding microplastics in eight samples. The study suggests the olfactory pathway might be a route for microplastics to enter the brain. Lead author Dr. Thais Mauad highlighted that previous studies have shown air pollution particles in the olfactory bulb, supporting this hypothesis.
