Microplastics have become a pervasive contaminant, infiltrating our environment and bodies, leading to potential health risks, including neurological disorders. As research continues to uncover the dangers of microplastics, it is crucial to explore effective methods for their removal from the human body.
The Serious Health Risks of Microplastics
Microplastics can enter the human body through ingestion, inhalation, and even dermal exposure. Once inside, they can accumulate in various organs, potentially causing inflammation, oxidative stress, and neurotoxicity. The urgency to eliminate these particles is underscored by their association with serious health issues, including cognitive decline and other neurological disorders, including non-diabetic peripheral neuropathy.
After entering the human body through ingestion, inhalation, and dermal exposure, and subsequently penetrating the gut barrier and entering the bloodstream, they may accumulate in various tissues, including peripheral nerves. This accumulation triggers oxidative stress and inflammation, leading to the production of reactive oxygen species (ROS) that damage nerve fibers and disrupt normal nerve function. As a result, damage may manifest as symptoms of non-diabetic peripheral neuropathy (NDPN), including numbness or tingling in the toes.
The human liver processes various toxic substances, including those derived from PVC and PE. However, excessive exposure to these materials—especially in their microplastic form—can overwhelm the liver’s detoxification capabilities, leading to significant health risks.
It’s Raining Plastic
Researchers investigating nitrogen pollution in the Southern Rocky Mountains of Colorado collected rain, snow, and fog samples from eight diverse regions, only to discover alarming levels of microplastics present in over 90% of their samples. This finding, published by the US Geological Survey (USGS), revealed that microplastic contamination was not limited to urban areas but also affected remote locations, indicating a widespread issue of “plastic rain.” The study included over 35 microscopic images of the detected microplastics, showcasing multicolored fibers, beads, and shards. Although the researchers did not initially plan to evaluate microplastics, their findings suggest this is merely the beginning of a larger environmental concern, as evidence mounts that microplastics are infiltrating even the most pristine ecosystems worldwide[33].
Metabolism of PVC and PE
The human liver plays a crucial role in metabolizing and detoxifying various substances, including harmful compounds like polyvinyl chloride (PVC) and polyethylene (PE). Here’s how the liver interacts with these materials:
Vinyl Chloride and Its Metabolites
– PVC is produced from vinyl chloride, a toxic compound that can enter the body through inhalation or ingestion. The liver metabolizes vinyl chloride into several substances, some of which may be more harmful than the original compound. This process can lead to liver damage if the exposure exceeds the liver’s capacity to detoxify it[8][12].
– The liver converts vinyl chloride into metabolites that can then be excreted via urine. However, some metabolites linger longer in the body, potentially causing cellular damage[8].
Microplastics and Liver Damage
– Recent studies indicate that microplastics (MPs), which include fragments of PVC and PE, can accumulate in the liver. Exposure to MPs has been shown to cause morphological changes in liver cells, including hepatocyte hypertrophy and inflammation[9][11].
– The size of the microplastics influences their accumulation; smaller particles are more readily absorbed into the bloodstream and transported to the liver, where they can disrupt normal metabolic processes and lead to oxidative stress[9][11].
Mechanisms of Toxicity
– The liver is central to detoxifying xenobiotics (foreign substances) that enter the body. When MPs are present, they may alter gut microbiota composition, leading to dysbiosis, which in turn affects liver function[11]. This interaction highlights the importance of the gut-liver axis in mediating the effects of environmental toxins.
– Studies have documented that individuals with liver diseases, such as cirrhosis, show higher concentrations of microplastics in their liver tissues compared to healthy individuals, suggesting a potential link between chronic liver conditions and MP accumulation[10][11].
Effective Strategies for Removing Microplastics: A Fact-Checked Overview
Microplastics, including polyethylene (PE) and polyvinyl chloride (PVC), are pervasive environmental contaminants that have raised concerns regarding their accumulation in the human body. While various strategies have been proposed for their removal, it is crucial to evaluate their effectiveness based on scientific evidence.
1. Essential Oils
– Lemon Oil: Lemon essential oil contains limonene, which has solvent properties that can dissolve specific types of plastics, particularly low-density polyethylene (LDPE). However, limonene is less effective against high-density polyethylene (HDPE) and PVC, which are more chemically resistant[15]. While some anecdotal claims suggest that lemon oil may aid in detoxification, there is no substantial evidence to support its effectiveness in breaking down microplastics within the human body[14][15].
– Other Citrus Oils: Similar to lemon oil, other citrus oils like orange and grapefruit contain limonene. While they may promote liver function and metabolic pathways, their role in directly dissolving microplastics in the body remains unproven[14].
2. Phospholipid Supplements
Phospholipids are essential for cellular health and may assist in detoxifying fat-soluble substances. However, they do not encapsulate or remove microplastics directly. Instead, they may help mitigate the effects of toxins associated with microplastics, supporting the body’s natural detox processes[14].
3. Liver Support
Supporting liver function through hydration and a diet rich in antioxidants can enhance the body’s ability to process and eliminate toxins. Foods such as berries and leafy greens are beneficial, but there is no direct evidence that they specifically target microplastics[14].
4. Infrared Sauna Therapy
Infrared saunas may promote sweating and assist in general detoxification. While this method is known to enhance overall detox pathways, specific evidence regarding its effectiveness against microplastics is limited[14].
5. Dietary Choices
A diet rich in cruciferous vegetables, leafy greens, berries, and healthy fats supports detoxification processes. These foods contain compounds that promote liver function but do not specifically target microplastic removal from the body[14].
6. Hydration
Adequate hydration is essential for kidney function and helps flush out toxins from the bloodstream. While drinking plenty of water aids in general detoxification, it does not specifically remove microplastics[14].
7. Blood Filtering Techniques
Emerging blood filtration methods show promise for removing microplastics from the bloodstream. Techniques such as dialysis or specialized filters can physically remove contaminants from blood samples. Some studies indicate that plasma donation may reduce detectable levels of microplastics by allowing the body to regenerate new blood[17]. However, these methods are still under research for practical application in humans[14][17].
8. EDTA Suppositories
There is currently no substantial evidence that EDTA can effectively remove microplastics from the human body. Microplastics are complex polymers that do not readily bind with EDTA like heavy metals do[24]. Thus, while EDTA may aid in heavy metal detoxification, its role in microplastic removal remains unproven. NOTE: The use of EDTA can lead to depletion of essential minerals and vitamins in the body. If used improperly or without medical supervision, it could cause adverse effects[24][25]. Therefore, any use of EDTA should be approached with caution and ideally under medical guidance.
9. Zeolite
Zeolite has been suggested as a potential agent for removing microplastics, including polyethylene (PE) and polyvinyl chloride (PVC), from the human body. Nanosized zeolite particles can penetrate deep into body tissues, where microplastics may accumulate, and are capable of trapping various toxins, including plastic compounds. Research indicates that zeolite can effectively adsorb microplastics, with some studies reporting removal efficiencies exceeding 90% in controlled environments. However, specific evidence regarding zeolite’s effectiveness in eliminating PE and PVC from the human body is limited. While zeolite shows promise for detoxification, further research is needed to establish its safety and efficacy for this purpose in humans [27][29][30].
10. Chlorella
Chlorella vulgaris, a type of green microalgae, has gained attention for its potential to aid in the removal of microplastics from the human body. Research indicates that dietary chlorella can enter the bloodstream and bind with microplastics, facilitating their excretion. This microalga produces exopolysaccharides (EPS), which enhance the aggregation of microplastics, thereby increasing their removal efficiency. Some studies suggest that chlorella can effectively bind with small microplastics, making it beneficial for detoxification purposes. In addition to chlorella, a multi-faceted approach involving probiotics, activated charcoal, and antioxidants is recommended to support the body’s natural detoxification processes. Maintaining a healthy diet rich in cruciferous vegetables, leafy greens, citrus fruits, garlic, ginger, turmeric, and green tea can further enhance the body’s ability to eliminate toxins, including microplastics. While chlorella shows promise in addressing microplastic contamination within the body, more research is needed to fully understand its efficacy and mechanisms of action [43][47][48].
11. Surgical Removal
In cases where microplastics cause significant health issues or blockages, surgical intervention may be necessary. This method allows for the direct extraction of plastic materials from the body, particularly in instances where they accumulate in organs or tissues. Surgical techniques can be employed to remove larger fragments that may pose a risk to health, especially in the gastrointestinal tract or other affected areas. Studies have documented instances of microplastics found in human tissues during surgical procedures, highlighting the need for careful monitoring and potential removal strategies during such interventions [34][36].
12. Biodegradation via Microbial Action
Microbial biodegradation is a promising approach for breaking down plastics into smaller, less harmful components. Certain microorganisms can metabolize plastics, including PE and PVC, leading to their degradation into non-toxic byproducts[35].. Research has shown that microbial biofilms can form on plastic surfaces, facilitating the breakdown of these materials through enzymatic action [4][6]. This method is being explored not only for environmental cleanup but also for potential applications in human health to mitigate plastic accumulation.
13. Chemical Detoxification
Chemical detoxification involves using specific agents that can bind to or chemically alter microplastics within the body. This could lead to their transformation into smaller, less harmful molecules that can be more easily excreted. Research into pharmacokinetics suggests that understanding how microplastics interact with biological systems may enable the development of targeted chemical therapies that facilitate their removal [34][41]. Although still largely theoretical, this approach could open new avenues for treating plastic-related health issues.
14. Activated Charcoal Administration
Activated charcoal is known for its ability to adsorb various toxins in the gastrointestinal tract, potentially including microplastics. While its effectiveness specifically against plastics is not fully established, activated charcoal could help reduce overall toxin load and facilitate the excretion of contaminants through feces [35][40]. This method has been used in clinical settings for poisoning and overdose cases and might be adapted for addressing microplastic exposure.
15. Dietary Fiber Intake
Increasing dietary fiber intake can promote gastrointestinal health and may assist in the expulsion of small plastic particles through bowel movements. High-fiber foods can help bulk up stool and enhance regularity, potentially aiding in the elimination of microplastics that have been ingested [35][37]. While applesauce and other fiber-rich foods contribute positively to digestive health and overall well-being, they are not proven methods for removing nanoplastics from the human body.
16. Innovative Extraction Techniques
Recent research has focused on eco-friendly solvents capable of removing nanoplastics from water environments by binding to them for extraction. While these methods illustrate potential avenues for biological applications, they are primarily environmental solutions rather than direct treatments for human health[14][19].
Conclusion
While various strategies have been proposed to address microplastic contamination in the human body, only a few show promise based on current scientific understanding. Essential oils may offer some benefits for overall health but lack specific evidence for removing microplastics. Supporting liver function through diet and hydration is beneficial for general detoxification but does not directly target microplastic removal. Blood filtration techniques represent a more promising avenue but require further research before being considered viable options for human application.
