Plastic is a critical component of the pollution problem, and its presence in the air is a growing concern. Microplastics, tiny plastic particles, are now recognised to be in the air we breathe, with potential impacts on human health and the environment. These particles can be found indoors and outdoors, travelling thousands of miles and affecting cloud formation, with potential implications for temperature, rainfall, and climate change. While the exact health effects are still being studied, the presence of microplastics in human lungs, placenta, liver, and breast milk is a cause for concern. The sources of these airborne microplastics are varied, including roads, agricultural dust, oceans, cosmetics, clothing, and packaging materials. The issue of plastic in the air highlights the need for collective efforts to reduce plastic consumption and improve waste management, with a particular focus on regulation and sustainable alternatives.

What You'll Learn
Plastic is found in human lungs
Plastic is so lightweight that even chunks as small as tens of micrometres across—the width of a human hair—can be lifted and blown great distances. These particles can stay in the air for hours, days, or even weeks, and can travel thousands of miles from their source. Because of this, microplastics have been found in the air, drinking water, rainfall, snowfall, oceans, and even in the lungs of humans.
In 2022, for the first time, microplastics were found in the lungs of living people. The research, which was accepted into the peer-reviewed journal "Science of the Total Environment", underlines the "mounting concern" around the reach of microplastics worldwide and their growing health consequences. The study found microplastics in 11 out of 13 cases, with the most abundant particles being polypropylene and polyethylene terephthalate (PET), often used in plastic packaging and bottles, respectively.
The long-term health consequences of microplastic pollution are still unknown. However, Dr. Onugha, a thoracic surgeon and assistant professor of thoracic surgery, commented that "the body does not like things that cause inflammation [...] and things that are foreign [like plastics]. So, if it leads to chronic inflammation, that’s where you can have things that develop years down the road."
Microplastics enter the atmosphere through various means, including disposable bags, cosmetics, clothing, industrial processes, and packaging materials. The cosmetics industry, in particular, is a large contributor to microplastics in the atmosphere, as they can be added to the formula of certain products such as scrubs and facial products.

Plastic is burned, releasing toxins
Plastic is a significant contributor to air pollution. It has been found that plastic particles can be transported by wind currents to the most remote parts of the Earth in a matter of days. Studies have shown that airborne microplastic concentrations range from 0.01 particles per cubic meter over the western Pacific Ocean to several thousand particles per cubic meter in cities like London and Beijing.
Burning plastic can have detrimental effects on the environment and human health. Plastic is often burned as a method of waste disposal, especially in regions lacking solid waste collection services and landfills. However, this practice releases various toxic chemicals and gases into the atmosphere, contributing to air pollution and posing risks to human health.
The burning of plastic releases toxic chemicals such as nitrogen oxides, sulfur dioxide, volatile organic compounds (VOCs), and polycyclic organic matter (POMs). It also emits heavy metals and other toxic chemicals, including dioxins, mercury, polychlorinated biphenyls, benzo(a)pyrene, and polyaromatic hydrocarbons (PAHs). Many of these substances are potent carcinogens, contributing to long-term health issues and an increased risk of cancer.
Additionally, the incomplete combustion of plastic produces smoke, which contains fine particulate matter and toxic gases. These particles are small enough to be inhaled, leading to respiratory issues and other health complications. The smoke released from burning plastic can cause immediate dangers, such as burns to the throat and lungs, and even result in cardiac arrest due to excessive smoke inhalation.
The toxins released from burning plastic can also impact the environment. Dioxins, for example, can adhere to the waxy surface of leaves and enter the food chain. Animals can ingest plastic debris, causing harm to their health, and larger pieces of plastic can become breeding grounds for diseases by trapping water and providing habitats for mosquitoes.

Plastic affects cloud formation
Plastic is so lightweight that even chunks as small as tens of micrometers across (the width of a human hair) can be lifted and blown great distances. These particles can travel thousands of miles and stay in the air for hours, days, or even weeks.
Scientists have found microplastics in some of the most pristine environments on Earth, from the Mariana Trench to Mount Everest, and in human lungs.
In the lab, preliminary tests show that battered plastic pieces can be potent cloud-makers. Microplastics act as ice nucleating particles, microscopic aerosols that facilitate the formation of ice crystals in clouds. This means that microplastics could impact precipitation patterns, weather forecasting, climate modelling, and even aviation safety.
The average temperature at which the droplets froze in the presence of microplastics was 5-10 degrees warmer than droplets without microplastics. Skies heavily polluted with plastic will probably make both more high-altitude ice clouds, which tend to warm the Earth's surface, and more low-altitude water clouds, which tend to cool the Earth.

Plastic is in drinking water, rainfall, and snowfall
Plastic is ubiquitous in our environment, and its presence in the air we breathe is a growing concern. Recent studies have confirmed that microscopic pieces of plastic, known as microplastics, are being transported through the air and can be inhaled, potentially impacting our health. This plastic pollution in the air has far-reaching consequences, as it can travel thousands of miles and affect the formation of clouds, influencing temperature, rainfall, and even contributing to climate change.
One of the alarming findings related to plastic pollution in the air is its presence in drinking water. Researchers from the National Institutes of Health (NIH) have developed an advanced imaging technique that detected a significant number of nanoplastics in single-use bottled water. These nanoplastics, smaller than 1 μm in size, are invisible to the naked eye and can easily enter the body's cells and tissues. The detection of such minute plastic particles in bottled water raises concerns about the potential impact on human health, especially considering the widespread consumption of bottled water globally.
The issue of plastic in drinking water is not limited to bottled water. While the presence of microplastics in bottled water highlights the pervasiveness of plastic pollution, it is essential to recognize that tap water is also at risk. Indoor air samples have shown the presence of microplastics, and these particles can find their way into our drinking water supplies. The potential health effects of ingesting these tiny plastic particles are not yet fully understood, but ongoing research aims to address this knowledge gap.
In addition to drinking water, plastic pollution has been detected in rainfall and snowfall. In 2019, researchers found microplastics in the Pyrenees that were attributed to rain or snowfall. This discovery was followed by Janice Brahney's high-profile study, which revealed substantial amounts of plastic in federally protected areas of the United States. The colorful bits of gunk in her ground-based filters indicated the presence of plastic in the atmosphere. Furthermore, snow samples from the Arctic Circle have yielded concerning results, with up to 14,400 pieces of microplastic per liter detected, showcasing the far-reaching extent of plastic pollution.

Plastic is in cosmetics and clothing
Plastic is everywhere, even in the air we breathe. Recent studies have confirmed that microscopic pieces of plastic can seed clouds and travel thousands of miles from their source. While the exact amount of plastic in the air is difficult to determine, studies have shown that concentrations of airborne microplastics can range from 0.01 particles per cubic meter over the western Pacific Ocean to several thousand particles per cubic meter in cities like London and Beijing.
One of the sources of plastic in the air is the cosmetics industry, which is a large contributor to microplastics in the atmosphere. Microplastics can be found in the ingredients of up to 87% of products from leading cosmetics brands. These microplastics are added to cosmetics as exfoliators, stabilizers, or to improve texture. They are commonly found in facial scrub solutions, body wash gels, skin care products, eyeshadow, blush, bronzer, lipstick, and lip gloss. The packaging of cosmetic products is also a significant source of plastic pollution, with the personal care and beauty industry producing more than 120 billion units of packaging globally every year, most of which are not truly recyclable.
The clothing industry also contributes to the presence of plastic in the air. Microplastics, in the form of microfibers, are used in textiles and can be released into the atmosphere through wear and tear or washing of the clothing.
The presence of plastic in the air has significant environmental and health implications. Plastic particles can go through the evaporation and precipitation process, ending up in drinking water, rainfall, snowfall, and oceans. They can also be carried by wind currents to remote parts of the Earth, affecting cloud formation and potentially impacting temperature, rainfall, and climate change.
