Plastic is everywhere—in the air, soil, and oceans. It's no surprise that humans ingest it too. Microplastics, tiny plastic particles, can be found in the food we eat, the water we drink, and even in our lungs. While ingesting small amounts of plastic is usually harmless, with the plastic passing through the digestive system, larger pieces of plastic or sharp objects can cause choking, internal bleeding, or gastrointestinal issues. Additionally, certain plastics may release harmful chemicals, and microplastics can damage human cells, decrease reproductive health, and disrupt the endocrine system. Ingesting plastic is often accidental, but it highlights the need to reduce plastic consumption and limit plastic waste to protect human health and the environment.

Ingesting plastic is not toxic, but large quantities may cause harm
Ingesting plastic is not toxic, and a small piece of plastic will usually pass harmlessly through the digestive tract. However, larger quantities of plastic or sharp objects can cause harm. If you swallow a large piece of plastic, you may experience symptoms such as nausea, vomiting, stomach pain, or constipation as your body tries to expel the foreign object. If the plastic is sharp, it could cut your digestive tract and cause internal bleeding.
Microplastics, or plastic particles smaller than 5mm, are commonly found in the environment and can enter the human body through food, water, and even the air we breathe. These tiny particles can pass through cell membranes and potentially cause damage at a cellular level. They can also act as a vessel for harmful chemicals to enter the body, such as styrene and phthalates, which are suspected carcinogens and endocrine disruptors.
To reduce your risk of ingesting plastic, it is recommended to avoid processed foods and opt for fresh fruits and vegetables. Cut back on canned goods, as these often have linings containing BPA. Pay attention to recycling codes and avoid plastic with known risks, such as PVC and polystyrene.
If you accidentally ingest plastic, do not induce vomiting as it can cause choking and throat pain. Instead, seek medical advice if you experience any discomfort or other symptoms, such as vomiting, abdominal pain, blood in the stool, difficulty breathing, wheezing, or chest pain.

Microplastics can enter the body through food, drink, and air
Ingesting plastic is not uncommon, and it is generally accepted that small pieces of plastic will pass harmlessly through the digestive tract. However, larger pieces of plastic can cause choking, abdominal pain, vomiting, bleeding, and even poisoning.
Microplastics, on the other hand, are extremely small pieces of plastic debris, often measuring less than 1 millimetre in length and are commonly found in the environment. These tiny particles can enter the human body through various pathways, including food, drink, and air.
Microplastics can contaminate food, especially when food is packaged in plastic. Processed foods and canned goods are more likely to be exposed to plastic packaging, increasing the risk of microplastic contamination. Plastic food packaging can also release chemicals, such as styrene and phthalates, which can contaminate food. These chemicals have been linked to potential health risks, including hormonal disruptions and increased chances of certain cancers.
Water is another source of microplastic ingestion. These particles can be found in drinking water and are also present in the air, eventually settling into the soil and water systems. They can also enter water systems through the use of toiletries that contain liquid plastics, such as lotions, hair conditioners, and toothpastes.
The air we breathe also contains microplastics, which can be inhaled. These particles can be as small as nanoscale, and they are often derived from larger plastic items that have broken down due to environmental factors. The air in homes and indoor spaces may have lower concentrations of microplastics, which likely come from textiles such as clothes, carpets, and curtains.
While the immediate health effects of ingesting microplastics are not fully understood, there are concerns about their long-term impact. Microplastics can pass through cell membranes and potentially cause damage at a cellular level. They can also be absorbed by the intestines and travel to other body parts through blood circulation, potentially affecting multiple organs. Research has shown that microplastics can impact macrophages, altering their function and causing them to release inflammatory molecules.

Microplastics can cause damage at a cellular level and disrupt the endocrine system
Ingesting plastic is not uncommon, and while it is not toxic, it can cause harm. Microplastics, in particular, can enter the human body through inhalation or ingestion. They are found in our drinking water, whether from the tap or bottled, and in our food. Studies have found microplastics in everyday fruits and vegetables, and wheat and lettuce plants have been observed to take up microplastic particles from the soil.
Once inside the body, microplastics can pass through the intestinal barrier and travel to other body parts via blood circulation. They can also pass through cell membranes, potentially causing damage at a cellular level. Research has shown that microplastics can cause oxidative stress and DNA damage, with high variability between cell lines. They can also disrupt the gut microbiome, leading to inflammation, and negatively impact learning and memory.
Furthermore, microplastics can disrupt the endocrine system, which is responsible for making the hormones that govern processes such as growth and development, metabolism, appetite, mood, and certain aspects of reproduction. Chemicals like bisphenol A (BPA), phthalates, and per- and polyfluoroalkyl substances (PFAS) are known to imitate hormones and disrupt the endocrine system. This can have a profound impact, especially during fetal development. Studies in mice have shown that exposure to microplastics can lead to lower sperm quality and testosterone levels, affecting male fertility.
While the full extent of the damage caused by microplastics is not yet clear, researchers are concerned about their potential impact on human health. Further studies are needed to understand how microplastics are processed by the human body and the long-term effects of exposure.

Polystyrene and PVC plastics may release harmful chemicals
Ingesting plastic is generally not toxic. Small pieces of plastic will usually pass through the digestive system without causing harm. However, polystyrene and PVC plastics are exceptions to this rule. They are considered among the most toxic plastics and the hardest to recycle.
Polystyrene is a type of thermoplastic made from styrene, a suspected carcinogen. It is commonly used in disposable cups and takeout containers and can release styrene, which contaminates the air, water, and communities that work and live near these facilities. Over fifty chemical byproducts are released during the manufacturing of polystyrene. The US Department of Health and Human Services has identified styrene as "reasonably anticipated to be a human carcinogen," and reports that styrene exposure is linked to "increased risks for leukemia, lymphoma, or all lymphohematopoietic cancer." One of the greatest sources of exposure to styrene is from eating food contaminated by styrene. Polystyrene also contains harmful additives such as phthalates and flame retardants, which can migrate or leach out, exposing consumers when they come into contact with products or when they contaminate indoor air, dust, drinking water, and food.
PVC, or polyvinyl chloride, is often used as cling wrap for food storage and may leach phthalates that can disrupt hormones. It has been evidenced to be a carcinogen, causing rare liver cancer, disrupting male endocrine systems, causing short-term lung irritation and dizziness, inducing reproductive and birth defects, impairing child development, and suppressing the immune system.
To reduce exposure to these harmful chemicals, it is recommended to avoid processed foods and opt for fresh produce, cut back on canned goods, and pay attention to recycling codes on plastic packaging, avoiding those with known risks such as #3 (PVC) and #6 (polystyrene).

If ingested plastic is sharp, it may cut the digestive tract
Ingesting plastic is a common occurrence, and while plastic is not inherently toxic, it does pose certain risks. If a person swallows a small piece of plastic, it usually passes harmlessly through their digestive tract. However, if the ingested plastic is sharp, it poses a severe risk of cutting the digestive tract, leading to internal bleeding.
The potential dangers of ingesting plastic depend on various factors, including the size, shape, and type of plastic, as well as individual factors like metabolism and overall health. Sharp plastic objects, such as broken utensils or damaged containers, can cause physical damage to the digestive tract. This can result in internal bleeding and require immediate medical attention.
In the event of swallowing a sharp piece of plastic, it is crucial to seek expert guidance from healthcare professionals. Symptoms such as abdominal pain, vomiting, cramping, blood in the stool, difficulty breathing, wheezing, or chest pain warrant immediate medical attention. It is also important to be vigilant about seeking help if there is any discomfort or concern after ingesting plastic, even without apparent symptoms.
To reduce the risk of ingesting sharp plastic, it is advisable to discard broken utensils, avoid using damaged or cracked plastic items, and opt for alternative products like paper straws or wooden forks. Additionally, it is essential to keep small plastic objects out of the reach of children to prevent accidental ingestion.
While ingesting a small piece of plastic may not always cause immediate harm, it is important to be cautious and seek appropriate guidance when necessary. The potential risks associated with ingesting sharp plastic objects highlight the importance of being vigilant about our exposure to plastic and taking preventive measures to ensure our safety.
