Story at-a-glance
- Researchers found 39 microplastics in surgical lung samples from 11 of 13 people. There were 12 types that would commonly be found in plastic bottles, twine, clothing and surgical masks
- A respirator specialist says surgical masks don’t meet the legal definition of a mask but rather are “breathing barriers.” He was emphatic they are shedding microplastics small enough to be inhaled
- A data analysis of cases, hospitalizations and deaths in Kansas revealed counties with mask mandates had higher mortality rates than those without mask mandates
- Once inhaled or consumed, microplastics can be found in your bloodstream in particles small enough to cross membrane barriers. It’s also found in an infant’s first stool, suggesting maternal exposure; an animal study found nanopolystryene particles in fetal brain, liver, kidney and lung tissue 24 hours after maternal exposure
The price that society will pay for the ubiquitous use and distribution of plastic particles has yet to be quantified. Evidence suggests that the long-term exposure to endocrine-disrupting chemicals like phthalates poses a significant danger to health and fertility.
Study Finds Microplastics in 11 Out of 13 Patient’s Lungs
Decades of research have shown that people breathe in microparticles of air pollution as well as consume them in food and water. A 2021 autopsy study10 showed microplastics in 13 of the 20 people analyzed and over 20 years ago a 1998 U.S. lung cancer study11 found plastic and fibers in 99 of the 114 lung samples that were examined.One team of scientists from Hull York Medical School sought to analyze the impact that inhaling microplastics has on human tissue. Past research has found synthetic fibers in lung tissue, but researchers wrote there were no robust studies confirming microplastics in lung tissue. The current study analyzed human lung tissue in 13 patients who had undergone lung surgery.
“Microplastics have previously been found in human cadaver autopsy samples — this is the first robust study to show microplastics in lungs from live people. It also shows that they are in the lower parts of the lung. Lung airways are very narrow so no one thought they could possibly get there, but they clearly have.
This data provides an important advance in the field of air pollution, microplastics and human health. The characterisation of types and levels of microplastics we have found can now inform realistic conditions for laboratory exposure experiments with the aim of determining health impacts.”Study authors found the subjects harbored 12 types of microplastics, “which have many uses and are commonly found in packaging, bottles, clothing, rope/twine, and many manufacturing processes. There were also considerably higher levels of microplastics in male patients compared to females.”16
Expert Says COVID Face Covers Are Not Masks
A study18 published in 2021 looked at the risks of wearing blue surgical face masks and inhaling microplastics. The researchers found that reusing masks could increase the risk of inhaling microplastic particles and that N95 respirators had the lowest number of microplastics released when compared to not wearing a mask.“A [proper] mask has engineered breathing openings in front of mouth and nose to ensure easy and effortless breathing. A breathing barrier is closed both over mouth and nose. And by doing that, it captures carbon dioxide that you exhale, forces you to re-inhale it, causing a reduction in your inhaled oxygen levels and causes excessive carbon dioxide. So, they’re not safe to wear.”He encourages people to cut one open and look at the loose fibers that are easily dislodged within the product.22
“The heat and moisture that it captures will cause the degradation of those fibres to break down smaller. Absolutely, people are inhaling [microplastic particles]. I’ve written very extensively on the hazards of these breathing barriers the last two years, I’ve spoken to scientists [and other] people for the last two years about people inhaling the fibres.
If you get the sensation that you’ve gotten a little bit of cat hair, or any type of irritation in the back of your throat after wearing them. That means you’re inhaling the fibres.”He went on to note that anyone exposed to these types of fibers in an occupational setting would be required to wear protection. Instead, people are using products that increase the risk of inhaling fibers that “break down very small and, well, what that’s going to do to people in the in the form of lung function — as well as toxicity overload in their body — I guess we’ll know in a few years.”23
Face Coverings Also Increase the Death Rate From COVID-19
German physician, Dr. Zacharias Fögen, published a study24 in the peer-reviewed journal Medicine, which analyzed data across counties in Kansas, comparing areas where there was a mask mandate against counties without a mandate.“The most important finding from this study is that contrary to the accepted thought that fewer people are dying because infection rates are reduced by masks, this was not the case. Results from this study strongly suggest that mask mandates actually caused about 1.5 times the number of deaths or ~50% more deaths compared to no mask mandates.
The mask mandates themselves have increased the CFR (case fatality rate) by 1.85 / 1.58 or by 85% / 58% in counties with mask mandates. It was also found that almost all of these additional deaths were attributed solely to COVID-19. This study revealed that wearing facemasks might impose a great risk on individuals, which would not be mitigated by a reduction in the infection rate.
The use of facemasks, therefore, might be unfit, if not contraindicated, as an epidemiologic intervention against COVID-19.”Fögen notes two other large studies that found similar results with case fatality rates. The first was published in the journal Cureus27 and found no association between case numbers and mask compliance in Europe but a positive association with death and mask compliance.
Plastics Trigger Cell Damage and Death
Past research has highlighted the impact microplastics have on the environment, wildlife and human health. However, many studies have not drawn an association between microplastic consumption or inhalation and disease. Instead, they identify research gaps and recommend further study.29The study was a meta-regression analysis of the toxicological impact on human cells across 17 studies that compared the level of microplastics that cause cell damage. The researchers found that it was the irregularly shaped microplastics that cause cell damage and not the spherical microplastics that are normally used in laboratory experiments.
Where Does Plastic Pollution Go in Your Body?
Researchers have found that tiny microplastics are not only deposited in your lungs and gut but can also be found floating in your blood. Researchers from The Netherlands analyzed samples32 from 22 healthy volunteers and found plastic particles in 77% of the samples. These particles were 700 nanometers or greater in dimension, which is a size that can be absorbed across membranes.It appears that inhaling or consuming microplastics allows micro particles access to your bloodstream and then to your vital organs. While researchers have demonstrated that the irregularly shaped microplastics found in the environment cause cell damage and death, the long-term effects on disease have not been identified. Yet, you may be sure that cell damage and death do not occur without consequences.
