Plastic is everywhere. It's in our oceans, our food, our drinking water, and even in the air we breathe. It should come as no surprise, then, that microplastics—plastic fragments less than 5mm in diameter—have been found inside the human body. In fact, a recent study detected microplastics in human lung tissue, and another found a chemical used to make plastics in human organ tissue samples. While the health effects of microplastics on humans are still largely unknown, there are growing concerns about their potential impact on our health. With plastic production continuing to increase worldwide, it's crucial that we address plastic pollution and work towards understanding the full extent of its impact on our bodies and the environment.

What You'll Learn
Microplastics are in our bodies
Plastics have become a ubiquitous part of modern life, but they've only been around since the mid-1800s and were not produced on a large scale until the 1950s. Today, plastic is used in most containers and packaging materials, as well as in fabrics, buildings, vehicles, and healthcare settings. The production of plastics worldwide has doubled in the last two decades, and it could take up to 1,000 years for some of the plastic being produced today to biodegrade.
Microplastics are plastic fragments less than 5mm in diameter, and nanoplastics are even smaller, with diameters of less than 0.001mm. They are created as plastics break down and degrade, and they are now found everywhere in the environment. They have been detected in the air, water, soil, food, and even household products like cosmetics and cleaning supplies.
It is therefore perhaps unsurprising that microplastics have been found inside human bodies. Scientists have discovered microplastics in human blood and tissue samples, including in the spleen, liver, colon, lungs, placenta, breast milk, testicles, hearts, and kidneys. They have also been found in fecal samples from people all over the world, confirming that humans ingest microplastics and that they pass through the digestive system.
While the health effects of microplastics on humans are not yet fully understood, there are concerns that they could be harmful. Chemicals often found in plastics are known to cause a range of health problems, including cancers, metabolic disorders, attention deficit/hyperactivity disorder, and fertility issues. Some studies have suggested that microplastics may also have toxic effects, including oxidative stress, DNA damage, organ dysfunction, immune response, neurotoxicity, and reproductive and developmental toxicity. There is also evidence that microplastics can carry antibiotic-resistant bacteria and other pathogens, and that they may magnify the potency of other toxicant exposures.
With microplastics so pervasive in the environment and in our bodies, there are urgent calls for more research and regulation to understand the potential health risks.

Plastic pollution
The environmental, social, economic, and health risks of plastics must be assessed alongside other environmental stressors like climate change, ecosystem degradation, and resource use. Plastic pollution can alter habitats and natural processes, reducing ecosystems' ability to adapt to climate change and directly affecting millions of people's livelihoods, food production capabilities, and social well-being. Every year, 19 to 23 million tonnes of plastic waste leak into aquatic ecosystems, polluting lakes, rivers, and seas. Every day, the equivalent of 2,000 garbage trucks full of plastic is dumped into the world's oceans, rivers, and lakes.
The convenience of plastics has led to a throw-away culture, revealing a dark side to the material. Today, single-use plastics account for 40% of the plastic produced annually. Many of these products, such as plastic bags and food wrappers, are used for just minutes or hours but can persist in the environment for hundreds of years. In recognition of this, some governments have moved to limit or ban plastic bags, with California recently passing legislation to ban all plastic bags by 2026.
Half of all plastics ever manufactured have been made in the last 20 years. Production increased exponentially, from 2.3 million tons in 1950 to 448 million tons by 2015. While plastics have brought many benefits, such as life-saving medical devices and space travel, the exponential growth in plastic production and the throw-away culture it has enabled have contributed significantly to the global plastic pollution crisis.

Health effects of chemicals in plastics
Plastic is now everywhere in the environment and in human bodies. Humans ingest microplastics, and they pass through the digestive system, as evidenced by their presence in fecal samples from around the world. Microplastics have also been found in human blood, lungs, and placenta. They have been linked to issues with fertility, biomarkers of colon and gut cancer, and potential respiratory problems.
The health effects of chemicals in plastics are wide-ranging and serious. As plastics are made from complex mixtures of chemicals, it is difficult to quantify the exact impact of each one. However, scientific results to date indicate that plastic causes diseases, disabilities, and premature death at every stage of its life cycle. The toxic chemical additives and pollutants found in plastics threaten human health on a global scale.
Some of the health issues that could be triggered by chemicals in plastic include low birth weights and preterm births, impaired fertility, maternal breast cancer risk, and problems with brain development in young children. Exposure to endocrine disruptors has been linked to reproductive disorders, development dysfunction, behavioural disorders, thyroid problems, low birth weight, diabetes and obesity, asthma, and breast and prostate cancers.
Vulnerable groups, including children, pregnant people, women, workers in the waste sector, and marginalized communities, are particularly exposed to toxic chemicals in plastics, raising concerns about human rights and environmental injustice. The adverse effects of plastic are particularly acute for children in the womb and young children, with increased risks of prematurity, stillbirth, birth defects of the reproductive organs, neurodevelopmental impairment, impaired lung growth, and childhood cancer.
In addition to the health effects of the chemicals themselves, the production of plastics also has important monetary costs, recently estimated to be more than $250 billion in 2015 globally and over $920 billion in the US alone for diseases and disabilities caused by plastic-associated chemicals.

Plastic production and uses
Plastic is a synthetic or semisynthetic material that uses polymers as its main ingredient. Polymers are long chains of large, repeating molecules. The word 'plastic' comes from the Ancient Greek 'plastikos', meaning 'capable of being shaped or moulded'. This refers to the plasticity of plastic, which allows it to be moulded, extruded, or compressed into a variety of shapes, including films, fibres, plates, tubes, bottles, and boxes.
The first fully synthetic plastic was Bakelite, invented in 1907 by Leo Baekeland, who coined the term 'plastics'. Plastics are usually derived from natural gas, petroleum, and other fossil fuels, as well as a small fraction from renewable materials such as polylactic acid. The production of plastic involves extracting and refining these raw materials to obtain useful chemicals, including monomers, which are the basic building blocks of polymers. Polymerisation is a process in the petroleum industry where monomers are converted into higher molecular weight hydrocarbons (polymers).
Plastics are used in a wide range of applications due to their adaptability, durability, flexibility, lightweight, nontoxicity, and inexpensive production. In developed economies, about a third of plastic is used in packaging, and another third in buildings for piping, plumbing, or vinyl siding. Plastics are also used in automobiles (up to 20%), furniture, and toys. In the developing world, the applications may differ; for example, 42% of India's plastic consumption is used in packaging.
The versatility and durability of plastics have made them ubiquitous in modern life. However, plastic pollution is a significant concern, with an estimated 350 million tonnes of plastic waste produced annually, and between 1 and 2 million tonnes entering the oceans each year. Plastic's persistence in the environment and its breakdown into microplastics and nanoplastics have raised concerns about its impact on human health. Microplastics have been found in human organs, and studies suggest they may harm fertility and increase cancer risk.

Banning plastic products
Plastic is everywhere. It is in the clothes we wear, the food we eat, and even the air we breathe. It is in the oceans, in the fish we eat, and, as recent studies have shown, it is in our bodies. Humans are now consuming and absorbing plastic through various means, and this has serious implications for our health.
Plastic is made from fossil fuels, and its production is linked to climate change, biodiversity loss, and health issues like asthma and cancer. It is also a significant source of pollution, with plastic waste clogging drainage systems and oceans, and posing a threat to marine life. The problem has become so severe that, in 2022, 175 nations agreed to work towards a legally binding global treaty to end plastic pollution by 2024.
To address this crisis, there have been growing calls for bans on single-use plastics, such as bags, straws, cutlery, and packaging. Some countries and states have already implemented bans on specific single-use plastic items, with varying levels of success. For example, California's ban on single-use plastic bags led to a significant reduction in plastic bag consumption and associated litter, while a similar ban in California included loopholes that allowed thicker plastic bags, resulting in an increase in plastic waste.
While banning certain single-use plastic items is a step in the right direction, it is just a drop in the ocean when it comes to tackling the vast plastic pollution problem. Plastic has become so ubiquitous in modern life that finding alternatives to specific plastic items can be challenging and may have unintended consequences. For instance, switching to glass bottles for liquids instead of plastic ones makes the product heavier, potentially requiring more trips for transportation. Similarly, paper production has a larger carbon footprint than plastic production.
However, these challenges do not mean that we should do nothing about the plastic crisis. Instead, we should view them as opportunities to innovate and find sustainable solutions. For example, at the University of Colorado Boulder, the Sustainability Council is working to eliminate all single-use plastics from vending machines, replacing plastic water bottles with aluminum cans, glass bottles, or cardboard boxes.
To effectively address the plastic pollution crisis, a multi-pronged approach is needed, combining policy changes, innovations in product design, and changes in consumer behavior. By working together, we can reduce our reliance on single-use plastics and minimize the harmful impacts of plastic pollution on our health and the environment.
