In today’s modern world, the pervasive use of plastics has brought about an alarming consequence: microplastics. These tiny particles, measuring less than 5mm in diameter, are infiltrating every nook and cranny of our environment, including our bodies.

While the detrimental impact of plastics on marine life is well-known, in fact it is being predicted that by 2050 there will be more plastic in the ocean than fish. The potential dangers of microplastics on human health are still emerging. Recent studies have revealed that microplastics can accumulate in our organs, penetrate our bloodstream, and even cross the placental barrier.

The consequences of this exposure are cause for concern. Microplastics have been linked to a range of health problems, including inflammation, respiratory issues, and hormonal disruption. Furthermore, scientists have raised the alarm about their potential to carry harmful chemicals and pathogens into our bodies. The other problem these small particles of plastic aren’t biodegradable decomposition can take hundreds or thousands of years.

As we uncover the hidden dangers of microplastics on human health, it is crucial to take action. From reducing plastic consumption and encouraging recycling to supporting research efforts, we can make a difference. Together, we can strive towards a future where our health isn’t compromised by the remnants of our disposable culture.

Sources of microplastic pollution

Microplastics have become ubiquitous in our environment, originating from a variety of sources. One of the primary sources of microplastics is the breakdown of larger plastic items, such as plastic bags, bottles, and packaging. As these plastics degrade due to weathering, UV exposure, and mechanical forces, they fragment into smaller and smaller pieces, ultimately becoming microplastics.

Another significant source of microplastics is the shedding of synthetic textiles. When we wash our clothes made of synthetic fabrics like polyester, nylon, or acrylic, tiny fibers are released into the wastewater, which can then make their way into the environment. Studies have shown that a single wash load can release hundreds of thousands of these microplastic fibers.

Microbeads, which are small, intentionally manufactured plastic particles found in personal care products like exfoliating scrubs, toothpaste, and cosmetics, are yet another source of microplastics. These microbeads are designed to be washed down the drain and can ultimately end up in waterways and the ocean.

Tire wear is another significant contributor to microplastic pollution. As vehicles travel on roads, the friction between the tires and the pavement causes tiny rubber particles to be released, which can then be carried by wind and water into the environment. Studies have estimated that tire wear accounts for a significant portion of the microplastics found in urban environments.

Finally, the breakdown of larger plastic items in the ocean, such as fishing nets, ropes, and other marine debris, can also contribute to the accumulation of microplastics in the aquatic environment. These microplastics can then be ingested by marine life and ultimately make their way into the human food chain.

How microplastics enter the human body

Microplastics have been found in a wide range of food and beverage sources, including seafood, table salt, bottled water, and even beer. As these tiny particles make their way into the human food chain, they can be inadvertently consumed by people.

One of the primary routes of microplastic exposure is through the consumption of seafood. Many marine organisms, such as fish, shellfish, and crustaceans, can ingest microplastics, either directly or through the consumption of smaller organisms that have already ingested them. When we eat these seafood items, we are also consuming the microplastics they have accumulated.

Another route of exposure is through the consumption of other food and beverage items that have been contaminated with microplastics. For example, studies have found microplastics in table salt, honey, and even beer, suggesting that these particles can be present in a wide range of food and drink products.

Inhalation is another potential pathway for microplastics to enter the human body. Microplastics can become airborne and be inhaled, particularly in urban areas with high levels of air pollution. These particles can then become lodged in the respiratory system, potentially causing respiratory issues or other health problems.

Finally, microplastics have also been found in drinking water, both from tap and bottled sources. When people consume this water, they are inadvertently ingesting these tiny plastic particles, which can then be absorbed into the bloodstream and distributed throughout the body.

Health risks associated with microplastic exposure

The potential health risks associated with microplastic exposure are still emerging, but the available evidence suggests that these tiny particles can have a range of adverse effects on human health.

One of the primary concerns is the ability of microplastics to accumulate in the human body and potentially cause inflammation. Studies have shown that microplastics can penetrate the gut lining and enter the bloodstream, where they can be transported to various organs, including the liver, kidneys, and even the brain.

Microplastics have also been linked to respiratory issues, as they can become lodged in the lungs and potentially cause irritation and inflammation. This can lead to breathing difficulties, coughing, and other respiratory symptoms.

Another concern is the potential for microplastics to disrupt the endocrine system, which is responsible for regulating hormones in the body. Some studies have suggested that certain types of microplastics may mimic the structure of natural hormones, leading to hormonal imbalances and potentially contributing to the development of conditions like infertility, breast cancer, and thyroid disorders.

Microplastics may also have the ability to carry harmful chemicals and pathogens into the human body. These particles can adsorb and transport a variety of pollutants, including heavy metals, persistent organic pollutants, and even bacteria and viruses. When these microplastics are ingested or inhaled, they can then release these harmful substances into the body, potentially leading to a range of health problems.

Additionally, there are concerns about the potential for microplastics to cross the placental barrier and reach the developing fetus. This could have implications for fetal development and potentially lead to long-term health consequences for the child.

Studies and research on the impact of microplastics on human health

As the issue of microplastics and their impact on human health has gained more attention, there has been a growing body of research exploring the potential risks and consequences.

One of the most comprehensive studies on the topic was published in the journal Environment International in 2019. The study, which reviewed over 50 existing studies, found that microplastics can be detected in a wide range of human tissues, including the gut, liver, and even the placenta. The researchers also highlighted the potential for microplastics to carry and transport harmful chemicals and pathogens into the human body.

Another study, published in the journal Environmental Science & Technology in 2021, focused on the potential impact of microplastics on the human immune system. The researchers found that exposure to microplastics can trigger an inflammatory response, leading to the activation of immune cells and the release of inflammatory cytokines. This could potentially contribute to the development of various health conditions, such as allergies, autoimmune disorders, and even cancer.

A study published in the journal Chemosphere in 2020 explored the potential for microplastics to disrupt the endocrine system. The researchers found that certain types of microplastics, such as those containing bisphenol A (BPA) or phthalates, can mimic the structure of natural hormones and interfere with their normal function. This could lead to hormonal imbalances and potentially contribute to the development of conditions like infertility, breast cancer, and thyroid disorders.

In addition to these studies, there is ongoing research exploring the potential for microplastics to cross the placental barrier and reach the developing fetus. A study published in the journal Environment International in 2020 found that microplastics can indeed be detected in the placenta, raising concerns about the potential impact on fetal development and long-term health outcomes.

Bottled water mostly comes in a plastic or what is called (PET) polyethylene terephthalate which interfere with the bodies hormones and are endocrine disruptors. So it should be no surprise that when they start to concentrate in the body that they will cause problems with hormones and now are being seen building up in the arteries, and causing bowel issues.

 

As the research continues to evolve, scientists are working to better understand the full extent of the health risks associated with microplastic exposure and to develop strategies for mitigating these risks.

Steps to reduce microplastic pollution

Given the growing concerns about the impact of microplastics on human health and the environment, it is crucial that we take action to reduce the amount of microplastics entering our ecosystems.

One of the most effective ways to address the issue is to reduce the overall consumption of plastic. This can be achieved through a variety of measures, such as encouraging the use of reusable bags, bottles, and containers, as well as promoting the use of alternative materials like paper, glass, or biodegradable options.

Additionally, improving waste management and recycling infrastructure can play a significant role in reducing microplastic pollution. Ensuring that plastic waste is properly collected, sorted, and recycled can help prevent it from breaking down into smaller microplastic particles and entering the environment.

Another important step is to support research and development efforts focused on finding alternative materials to replace plastic in various applications. This could include the development of biodegradable or compostable alternatives, as well as the exploration of new technologies that can effectively remove microplastics from the environment.

Educating the public about the issue of microplastics and their potential health risks is also crucial. By raising awareness and encouraging individuals to make more informed choices about their plastic consumption and waste management, we can collectively work towards reducing the amount of microplastics in our environment.

Lastly, it is important for governments and policymakers to take a more active role in addressing the issue of microplastic pollution. This could include the implementation of regulations, such as bans on certain types of single-use plastics or the introduction of extended producer responsibility schemes, which hold manufacturers accountable for the waste they generate.

Can You Filter Microplastics Out of Drinking Water?

The answer to that question is yes they can be removed from your drinking water. However you have to employ the right filter or you won’t take all of the plastic out of the water. There are two filter systems that are being used for this purpose and we will go through these option to find the best solution:

Carbon Filtration

The first kind of carbon filter is called a (GAC) granular activated carbon which can remove particles from 0.8 to 1.0 mm.

The second carbon filter is called a carbon block filter and can remove particles down to .18 mm.

Both these carbon filters are good but don’t take all of the micoplastics out of the drinking water which is our objective.

Reverse Osmosis

 This filter by far exceeds any of the carbon filters. The reverse osmosis drinking water system can take out particles down to 0.0001 microns which eliminates all microplastics from the water.

The role of government and organizations in addressing the issue

Governments and organizations have a critical role to play in addressing the issue of microplastic pollution and its impact on human health.

At the governmental level, policymakers can implement a range of measures to tackle the problem. This could include the introduction of bans or restrictions on the use of certain types of plastics, such as microbeads in personal care products, as well as the implementation of extended producer responsibility schemes that hold manufacturers accountable for the waste they generate.

Governments can also invest in research and development efforts to find alternative materials and technologies that can effectively remove microplastics from the environment. Additionally, they can provide funding and support for educational campaigns and public awareness initiatives to help citizens understand the importance of reducing plastic consumption and properly disposing of waste.

International organizations, such as the United Nations Environment Programme (UNEP) and the World Health Organization (WHO), have also been actively involved in addressing the issue of microplastics. These organizations have played a crucial role in raising global awareness, coordinating research efforts, and providing guidance to member states on effective strategies for addressing microplastic pollution.

Non-governmental organizations (NGOs) and environmental advocacy groups have also been instrumental in driving change. These organizations have been instrumental in lobbying for stricter regulations, supporting research initiatives, and engaging with the public to promote more sustainable practices.

Furthermore, industry associations and private sector entities can also play a significant role in addressing the issue of microplastics. By developing and implementing voluntary standards, promoting the use of alternative materials, and investing in research and innovation, these stakeholders can help drive the transition towards a more sustainable and plastic-free future.

Consumer choices to minimize microplastic exposure

As individuals, we can also play a crucial role in reducing our exposure to microplastics and minimizing our contribution to the problem.

One of the most effective ways to reduce microplastic exposure is to limit our consumption of single-use plastics. This includes items such as plastic bags, bottles, straws, and disposable food containers. Instead, we can opt for reusable alternatives, such as cloth bags, metal or glass water bottles, and sustainable food storage solutions.

When it comes to personal care products, it’s important to read the labels and avoid those that contain microbeads or other plastic-based ingredients. Look for products that use natural exfoliants, such as ground-up walnut shells or jojoba beads, instead of synthetic microbeads.

Choosing natural, unprocessed foods can also help reduce our exposure to microplastics. Opt for fresh, whole foods rather than heavily packaged or processed items, as these are more likely to contain microplastics from the packaging materials.

When purchasing seafood, it’s important to be mindful of the source and consider choosing options that are less likely to be contaminated with microplastics, such as farmed fish or shellfish from clean water sources.

Finally, proper waste management and recycling practices can also play a role in reducing microplastic pollution. Ensure that plastic waste is properly disposed of and recycled, rather than ending up in landfills or the environment, where it can break down into smaller microplastic particles.

By making conscious choices as consumers, we can collectively contribute to the reduction of microplastic pollution and minimize our exposure to these potentially harmful particles.

Alternative materials to plastic

As the concerns around microplastic pollution and its impact on human health continue to grow, there is an increasing focus on finding alternative materials to replace plastic in various applications.

One promising alternative is the use of biodegradable and compostable materials, such as those derived from plant-based sources. These include materials like bamboo, corn starch, and PLA (polylactic acid) derived from renewable resources. These alternatives can break down more easily in the environment, reducing the risk of microplastic accumulation.

Another option is the use of recycled materials, such as recycled paper, cardboard, or glass. These materials can be reused and repurposed, reducing the overall demand for new plastic production and the associated environmental impact.

Natural fibers, such as cotton, linen, or wool, can also serve as alternatives to synthetic textiles that shed microplastic fibers during washing. These natural materials are less likely to contribute to microplastic pollution and are generally more biodegradable.

Innovative materials, such as seaweed-based bioplastics or mushroom-derived materials, are also being explored as potential replacements for traditional plastic. These materials can be designed to have similar properties to plastic while being more environmentally friendly and biodegradable.

In addition to these alternatives, there is also a growing focus on the development of new technologies and processes that can effectively remove microplastics from the environment. This includes the use of filtration systems, adsorption techniques, and even biological methods that leverage the natural abilities of certain organisms to break down and remove microplastics.

As the search for sustainable alternatives continues, it is crucial that governments, industries, and consumers work together to support the development and adoption of these innovative materials and technologies. By transitioning away from traditional plastic, we can take meaningful steps towards reducing the impact of microplastics on human health and the environment.
