Microplastics Everywhere: A Hidden Threat to Our Health and Environment

Published on Quantum Server Networks – September 2025

Microplastics under the microscope

Plastic pollution is no longer confined to landfills, oceans, and visible litter on our streets. According to a recent report on Phys.org, microplastics are now infiltrating nearly every corner of our environment – and alarmingly, even our own bodies. These tiny fragments of plastic are being discovered in organs, blood, and even the human brain. The findings highlight an urgent challenge for scientists, policymakers, and society as a whole.

What Are Microplastics?

Microplastics are fragments of plastic smaller than 5 millimeters. When they become even smaller than one micrometer, they are classified as nanoplastics. Sources include household trash, industrial waste, food packaging, textiles, and even the breakdown of car tires. Every year, an estimated 3 million metric tons of microplastics enter the global environment – that’s more than 8,000 tons every single day.

How Do They Enter Our Bodies?

Researchers have shown that microplastics can enter the human body through multiple pathways:

  • Food and Drink: Studies have found microplastics in seafood, poultry, rice, fruit, vegetables, and even bottled water. On average, one liter of bottled water may contain up to 240,000 particles.
  • Everyday Use: Heating food in plastic containers or brewing tea in plastic tea bags releases thousands – and in some cases billions – of plastic particles.
  • Airborne Exposure: Plastic fibers from clothing, carpets, and furniture contribute to microplastics in the air we breathe daily.
  • Personal Care Products: Some shower gels, lotions, and toothpastes contain plastic microbeads and chemical additives that can be absorbed through the skin.

The Perth Trial: Investigating Human Health Impacts

One pioneering initiative, the PERTH Trial, led by immunologist Professor Michaela Lucas at Sir Charles Gairdner Hospital and the University of Western Australia, is examining how much plastic is entering our bodies and whether it poses measurable health risks. The trial is analyzing plastic intake from food, packaging, and household dust to better understand exposure routes.

Health Concerns: What Science Knows So Far

Microplastics are more than inert debris. They contain over 16,000 chemicals, including known carcinogens and hormone disruptors. In laboratory studies, microplastics have been shown to damage the intestines, lungs, liver, reproductive systems, and even nervous tissue in animals. Human research remains limited, but growing evidence raises red flags:

  • Cardiovascular Risks: A study found that patients with carotid artery plaque containing microplastics were four times more likely to suffer heart attacks.
  • Digestive Disorders: Patients with inflammatory bowel disease (IBD) were found to have significantly higher levels of microplastics in their stool than healthy individuals.
  • Neurological Links: Microplastics discovered in the brain were correlated with higher rates of dementia diagnoses, though causation has not been proven.
  • Reproductive Health: Plastic particles have been detected in semen, breastmilk, and even in newborn meconium, suggesting exposure starts before birth.

A Toxic Trojan Horse

As Dr. Sarah Dunlop of the Minderoo Foundation explains, “Plastic is toxic, whether virgin or recycled. It breaks up into micro and nanoplastics, acting like mini-Trojan horses that deliver toxic chemicals into our bodies.” Chemicals such as BPA and phthalates, common in plastics, are linked to developmental problems, hormonal disruption, and cancer.

What Can We Do?

While eliminating exposure entirely may be impossible, individuals can take steps to reduce risk:

  • Use glass, stainless steel, or ceramic containers instead of plastic.
  • Filter tap water with high-quality filtration systems.
  • Avoid heating food in plastic containers.
  • Reduce single-use plastics such as plastic bags, cutlery, and bottles.
  • Choose personal care products labeled “microbead-free.”

At a broader level, the fight against microplastic pollution requires systemic changes in manufacturing, waste management, and regulation. Just as with climate change, scientific research must drive policy shifts to reduce plastic dependency.

Conclusion

Microplastics are no longer an invisible menace. They are part of the air we breathe, the food we eat, and the water we drink. The scientific community is only beginning to understand their full impact on human health. What is clear, however, is that action is needed now – from individuals, industries, and governments – to mitigate the risks of living in a world increasingly saturated with plastic particles.

Quantum Chemistry Meets AI: A New Era for Molecular Machine Learning

Image
In a powerful leap forward for computational chemistry and materials design, researchers from Carnegie Mellon University have developed a new kind of molecular machine learning model—one that goes beyond simplistic molecular graphs and integrates fundamental principles of quantum chemistry. Their work, published in Nature Machine Intelligence , could radically enhance our ability to predict chemical behavior, optimize catalysts, and discover new drugs, all while using less data and gaining more scientific insight. The Problem: Traditional Molecular Representations Fall Short Molecular machine learning (ML) models underpin key processes in drug discovery, materials science, and catalysis. However, most existing models use simplified representations such as SMILES strings, 2D graphs, or coordinate matrices. These techniques often lack the quantum-chemical information that governs how molecules truly behave—particularly electron interactions that define reactivity, stability, and...

Water Simulations Under Scrutiny: Researchers Confirm Methodological Errors

Image
Accurate water simulations are vital for research in biomolecular structures, drug discovery, and materials science. But a recent study from Oak Ridge National Laboratory (ORNL) has revealed a potential pitfall in long-standing computational methods, raising concerns about the reliability of countless molecular dynamics studies. The Time Step Problem in Simulations At the heart of the issue is the “time step” used in simulations—the small intervals at which calculations are performed. Since the 1970s, scientists have used time steps of 2 femtoseconds (quadrillionths of a second) to simulate molecular motion efficiently. However, the ORNL team has shown that using this standard can introduce significant errors when modeling liquid water, potentially leading to inaccurate predictions of properties such as density, pressure, and hydration energies. “Using longer time steps is tempting because it reduces computational cost,” explained senior scientist Dilip Asthagiri. “But a...

CrystalGPT: Redefining Crystal Design with AI-Driven Predictions

Image
July 18, 2025 In a major leap for materials chemistry, researchers in the UK have developed Molecular Crystal Representation from Transformers (MCRT) —an AI model likened to ChatGPT for its transformative impact. Dubbed "CrystalGPT" , this foundation model rapidly predicts the physical properties of molecular crystals, revolutionizing how chemists design materials in silico . The AI Revolution in Crystal Design Understanding and predicting the properties of molecular crystals is critical for designing new materials for applications ranging from pharmaceuticals to energy storage. Traditional computational approaches, though powerful, are often resource-intensive and slow. Machine learning methods such as Smooth Overlap of Atomic Positions (SOAP) and atom-centred symmetry functions (ACSFs) have offered improvements, but they struggle with large datasets and subtle structural nuances. CrystalGPT, developed by a team led by Andy Cooper at the University of Liverpool, o...
