Plastic is everywhere. It is in the air we breathe, in the oceans, in freshwater, in the soil, and in thousands of species, including humans. Plastic is polluting the air we breathe, and it is a problem that requires collective efforts from governments, communities, and civil society to address it. Plastic waste is often burned, releasing toxins into the air and contributing to poor air quality and poor health outcomes. It has been linked to an increased risk of cardiovascular disease, respiratory ailments, and nervous system damage. In addition, the production of plastic releases greenhouse gases and other pollutants, worsening air quality and driving climate change. While the presence of plastics in landfills, oceans, and freshwater environments is well known, research into airborne particles is more recent. Scientists have found plastic in remote parts of the United States, Europe, China, the Arctic, and the French Pyrenees, transported there by wind currents and atmospheric currents. The cosmetics industry is also a large contributor to microplastics in the air, as they are added to the formulas of certain products. The impact of airborne plastic pollution on human health and the environment is a critical issue that needs to be addressed.

What You'll Learn
Plastic is found in remote areas
Plastic is found in the air we breathe, and in Earth's atmosphere, where it affects the climate. Research into airborne microplastics is a new field, but studies have found plastic in remote parts of the United States, Europe, China, the Arctic, the French Pyrenees, and the Fram Strait between Greenland and Svalbard.
In 2017, biogeochemist Janice Brahney from Utah State University collected dust samples from remote wilderness areas in the western US, including the High Uintas Wilderness in Utah and Rocky Mountain National Park, which do not receive a lot of human traffic. Under the microscope, she found "enormous amounts of plastic," in the form of fibres, spheres, and chunks, in a variety of colours.
Another study analysed ombrotrophic peat, a plant that is "cloud fed," receiving nutrients and water from the air. As these plants are extremely isolated, any pollution found in them would have to come from the atmosphere. The team found microplastic pollution in the peat dating back to the 1960s.
Wind currents can carry microplastics to remote parts of the Earth in a matter of days. These particles can also act as ice-nucleating particles (INPs) and cloud condensation nuclei (CCN). The presence of plastic in remote areas highlights the need for collective efforts from governments, communities, and civil society to reduce plastic consumption and improve waste management, as well as stricter regulations on plastic production and disposal.

Plastic is in the air we breathe
Microplastics are small pieces of plastic less than 5mm long. They can be formed when larger pieces of plastic age and fragment into smaller pieces, or when mechanical, chemical, and physical processes break down plastic into smaller sizes. They can also be formed when plastic trash is burned, releasing toxins into the air. Almost 40% of plastic waste is burned globally, which can lead to an increased risk of cardiovascular disease, respiratory ailments, and nervous system damage.
Microplastics can be found in the air in a variety of shapes and colors, and they can travel long distances through the air. They are transported via the atmosphere to remote areas, and can be carried by wind currents to the most remote parts of the Earth in a matter of days. They can also be carried by ocean air, sea spray, and fog.
The presence of microplastics in the air has potential health and environmental implications. Humans are exposed to microplastics through the air, water, food, and other pathways, often alongside other toxic pollutants and hazardous chemical compounds. While the influence of microplastics on the global climate is currently considered small, it is expected to increase in the future.
To address the issue of plastic in the air, regulators need to reduce plastic production and phase out hazardous chemicals. Individuals can also play a role by reducing plastic consumption and finding sustainable alternatives to plastic products.

Plastic is transported via wind
The presence of plastics in the air we breathe is a recent discovery. While the presence of plastics in landfills, oceans, and freshwater environments is well known, research into airborne particles is a new area of study. Scientists have found microplastics in 98% of the 339 samples they collected from national parks and wilderness areas in the United States. These samples included remote parts of the High Uintas Wilderness in Utah and Rocky Mountain National Park, areas that do not receive a lot of human traffic.
The plastic particles in the air come from a variety of sources. Some are formed when larger pieces of plastic trash age and fragment into smaller pieces. Other sources include cosmetics, clothing, industrial processes, and packaging materials. For example, microplastics can be added to the formula of certain cosmetic products such as scrubs and facial products.
The consequences of airborne microplastics on human and environmental health and the climate can be grave. Burning plastic waste is common, with almost 40% of plastic waste burned globally, releasing toxins into the air. This increases the risk of cardiovascular disease, respiratory ailments, and nervous system damage.
Regulators need to dramatically reduce plastic production and phase out hazardous chemicals to mitigate the health and environmental risks posed by airborne microplastics.

Plastic is in drinking water
Plastic is in the air we breathe and has been found in drinking water, rainfall, snowfall, rivers, lakes, and oceans. It is transported via the atmosphere to remote areas and can travel long distances through the air.
Microplastics, defined as small pieces of plastic less than 5 millimeters long, are created when larger pieces of plastic trash fragment into smaller pieces. These microplastics can then be transported through wind currents and deposited in remote wilderness areas. Scientists have found microplastics in 98% of the 339 samples they collected from national parks and wilderness areas in the United States, with plastics accounting for 4% of the dust particles tested.
The cosmetics industry is a large contributor to microplastics, as they can be added to the formula of certain products such as scrubs and facial products. Other sources of microplastics include clothing, industrial processes, and packaging materials. These microplastics are then released into the environment through exhaust vents and other means, contributing to plastic pollution in the air and water.
The presence of plastic in drinking water is a concern as it can absorb toxins and infiltrate our Earth's systems. While the full extent of the impact of microplastics in drinking water is not yet known, it is clear that plastic pollution is a critical issue that requires systemic efforts to address the full life cycle of plastics, from production to disposal. Reducing plastic consumption and improving waste management practices can help create pathways to cleaner air and water, ultimately benefiting human health and the environment.

Plastic is a health hazard
One of the primary concerns with plastic is the release of hazardous chemicals at various stages of its lifecycle, from production to disposal. Around a quarter of the over 10,000 unique chemicals used in plastics are of high or medium concern to human health and safety. These chemicals can act as endocrine disruptors, interfering with hormones responsible for healthy development. Exposure to these chemicals has been linked to reduced IQ and respiratory diseases in children, and obesity, cancer, and decreased fertility in adults. Studies have also found that women exposed to these chemicals may be more likely to develop reproductive disorders such as endometriosis.
In addition to the health hazards associated with chemical exposure from everyday plastics, there are also risks associated with air and water pollution resulting from plastic manufacturing. The extraction of oil and gas, particularly hydraulic fracturing for natural gas, releases toxic substances into the air and water. Workers in the plastic production industry and communities living near plastic production and waste disposal sites are at increased risk of exposure to hazardous air pollution. These individuals face higher risks of developing leukemia, lymphoma, brain cancer, and breast cancer. Children in these communities have also been found to have higher incidences of leukemia.
Furthermore, plastic production contributes to particulate matter air pollution, which has been linked to increased risks of cardiovascular disease, stroke, lung cancer, and diabetes in adults. In infants and children, exposure to this type of air pollution is associated with premature birth, low birth weight, impaired lung development, and asthma.
Recent studies have detected the presence of microplastics in human blood, lungs, and placenta, indicating that plastic pollutants are not only present in our environment but also in our bodies. As plastic production continues to increase, human exposure to plastic and its associated health risks will likely grow.
To minimize the health hazards associated with plastic, it is important to reduce the use of plastic products, dispose of plastic waste properly, and support efforts to regulate and reduce plastic production and pollution.
