We explain what microplastics are, and once you know that, the next question hot on everyone's lips is; “How much microplastic do we consume? So, we will we'll try to answer that as well. Plus; “Is that good for my health?” Shockingly nobody seems to know.
Microplastics do not biodegrade once they enter the environment. They build up in animals, especially fish and shellfish, and are thus eaten as food by humans. Microplastics have been discovered in freshwater, marine and terrestrial environments, as well as in food, tap water. They have been recorded in bottled water, and even blow in the wind for us to breathe in.
Microplastic pollution is a peril that has arisen under the radar of the world's scientists, who never noticed it happening until recently. Probably this was due to the plastic manufacturers who have never told anyone what they use. They have been claiming their additive information to be “commercial property” and secret. So, they don't publish what they add to their plastic to; make it resist cracking and colour it. Nor, do they ever explain what cheap “bulking materials” they add to keep the cost of their products down.
So, now it's urgent that everyone applies pressure to governments to make them require plastic manufacturers to explain exactly what added chemicals they use.

How do microplastics affect our health?
Because scientific study on the consequences of microplastics is in its early stages, no one knows how they may affect human health. Nor do we know how much microplastics we consume. But it's reasonable to assume that no amount of plastic in our stomachs is ever a healthy idea. It doesn't belong there, and that can't be argued. At this moment, further research is needed to determine exactly how consuming microplastics may damage human health.
Toxic chemicals and hormone-altering compounds found in microplastics can harm human health in areas ranging from reproduction to immune function,” Crowley has stated.
People may ask why we use plastic in so many things if it might be poisonous or detrimental to human health. Although it is not harmful when used for food packaging, plastic is utilised in a wide range of other items, and the plasticizers and additives used are not disclosed.
Many plastics are brittle without the addition of plasticizers, and the industry also incorporates inexpensive “bulkers” into the plastic. Then there are the colourants that are applied.
More research is needed to acquire a complete knowledge of the effects microplastics have on human health and the health of our seas. Many plastics, as can see, are created with ingredients that are not intended to be consumed.
Microplastics disrupt the ocean's capacity to sequester carbon through plankton, harming the air we breathe. While also endangering every ocean's crucial food chain.
Many microplastics that wind up in the water are devoured by a variety of marine species, the majority of which are fish, shellfish, and crustaceans. And because so many people consume these animals, they end up impacting human health as well.
Evidence Suggests Microplastics Damage Living Cells
Ordinary people may ask why we use so much plastic if it is harmful or detrimental to human health. That's an excellent question when we don't know how much microplastic we do consume.
While the health effects of digesting microplastics on live creatures are controversial, we have discovered a physical mechanism of mechanical stretching of model cell lipid membranes caused by adsorbed micrometre-sized microplastic particles widely present in oceans.
As a result, the membrane lifespan is drastically reduced. The impact of mechanical stretching of microplastics on live cell membranes was observed on red blood cells using the aspiration micropipette method. The mechanical stretching process discovered on lipid bilayers may help researchers better comprehend the influence of microplastic particles on biological systems.
Definition of Microplastics
Microplastics are described as bits of plastic trash that are smaller than 5mm in length. According to the Guardian, they are mainly formed by the decomposition of plastic waste and have been discovered in rivers, lakes, drinking water sources, and bottled water.
Health Effects of Microplastics
Important further study is needed to better understand the possible damages that microplastics might cause not only to the environment but also to human health.
The first experts to investigate the impacts of microplastics have already discovered a significant new source of microplastic. They discovered it right in front of our eyes! It is emitted from synthetic fabrics during laundering, then flows directly through sewage treatment plants and into all rivers and oceans.
Furthermore, once microplastics are present, there is no way to remove them from any living thing, man or animal. There is no supplier of wild seafood that can guarantee that their goods are free of microplastics.
Furthermore, experts must conclude that the effects of ingesting plastic-contaminated seafood on human health are not entirely understood.
Only recently has it been discovered that individuals are exposed to microplastics not only via the food we consume but also through the air we breathe.
According to a 2017 study on human health and microplastics, “we've just lately acknowledged human exposure to microplastics through the air.” So, we still need to identify the sources before answering the question of how much microplastic do we consume.
Lifetime Accumulation of Microplastic (MP) in Adults and Children
To that goal, a probabilistic lifetime MP exposure model for children and adults that accounts for the complete variability of mp across multiple known intake medium and global intake rates is constructed. The quantity of mp accumulated in human tissue and the amount ingested in the faeces are likewise assessed and quantified in terms of particle number and mass distributions.
Few states have enacted new health and safety rules, necessitating an urgent adoption of a definition of microplastics in drinking water by the state water board.
A consistent approach for testing drinking water for microplastics must be developed and implemented, as well as criteria for four years of testing. All nations should promptly establish legislation requiring, at the very least, the reporting of microplastics in drinking water, as well as public publication of the data.
The level of a lifelong accumulation of microplastics in children and adults can only be estimated once scientists agree on a method to test for microplastics. How much microplastic do we consume is a question unanswerable until scientists can agree on a reliable test method.
Microplastics aren't just from drinking water
The presence of plastic in drinking water is far from the sole cause for concern. Plastic disposed of in landfills will all degrade into microplastic over geological time and end up in the oceans. MEPs passed a plastics strategy in September 2018, with the goal of increasing the recycling rate of plastic waste in the EU. Furthermore, they urged the European Commission to implement an EU-wide ban on purposely added microplastics in items such as cosmetics and detergents by 2020, as well as to take steps to reduce microplastic release from textiles, tyres, paint, and cigarette butts.
Microplastics were researched by experts from the University of Basel in the isolated Antarctic Weddell Sea. The crew collected a total of 113 water samples from the surface and beneath the surface. They removed 770 microplastic particles, 45.5% of which were from marine paint. This was mostly ascribed to their own vessel.
Nowadays, the global society has succeeded to reduce main microplastics, particularly those that are unnecessary, such as microbeads. Microplastics, on the other hand, are still utilised in biomedical research and in air blasting technology to remove paint and corrosion from metal.
What Further Research Is Needed To Assess The Spread And Impact Of Microplastics?
What is being done about microplastics is a valid issue. We've previously said that there haven't been enough studies on microplastics. On August 22, 2019, the World Health Organization recommended a more thorough examination of microplastics in the environment and their possible effects on human health.
More study is needed on all types of microplastic pollution and the health effects of each one. There is a lot of work to be done before we can expect to know how much microplastic do we consume.
Exposure Linked to Infertility Inflammation and Cancer
The abrasion of plastic fragments discharged in the environment results in microplastic bits ranging in size from the diameter of a hair to noticeable shards.
Exposure to small plastics has been related to infertility, inflammation, and cancer in wildlife and laboratory animals. It may also be a contributing factor to obesity. The researchers are currently examining tissues for microplastics that accumulated over the donors' lives.
Plastic Model Simulations and Validation
Model simulations for continuous microplastic loading from several main sewage (wastewater) outfalls have revealed incremental microplastic buildup over time in Puget Sound's central and southern areas. This might jeopardise the health of oyster beds spanning the central and southern sounds.
Chemicals Leaching from Plastic in Gut
Chemicals seeping from plastic in the guts of animals and people are causing anxiety among scientists. This might happen as a result of:
- Desorption of persistent, bioaccumulating, and poisonous (PBT) substances from plastics,
- Leaching of plasticising compounds derived from plastics.
- Physical damage.
The following are the essential questions:
- How much of a direct physical impact do microplastics have, and
- To what degree do they serve as an extra vector for chemical pollutants, increasing or lowering PBT exposure in sensitive organisms?
- Once in the marine environment, microplastics are subjected to a variety of physical and chemical reactions, including:
- Biofouling and leaching, as well as secondary pollutant incorporation.
According to a recent assessment by the United Nations Food and Agriculture Organization, individuals do absorb trace levels of microplastics from aquatic life.
Fortunately, we don't consume nearly as much as other animals since humans primarily eat animal muscle tissue, leaving out the guts of fish, where the majority of microplastics and toxins gather.
Microplastics: How you can reduce them
Microplastics are becoming an increasing environmental hazard. It will take several years for research to determine just how hazardous microplastics are.
Given what we know about the health risks of plastics in general, it is probable that further detrimental impacts may emerge as study progresses.
Are you aware, for example, that they are tiny enough to find their way into tap water and may even pass past household water filters?
Microplastics are also used in a number of perfume encapsulating techniques. These scent oils are encapsulated and utilised in fabric softeners and detergents to provide long-lasting smells with less perfume.
But what exactly are microplastics, how did they come to be, and what can be done to mitigate the harm they pose?
Microplastics have appeared in news headlines with the same insidious ubiquity with which they pervade our daily lives and the natural environment in recent years. Apart from avoiding intentionally purchasing items containing them, such as toothpaste, we may all help to minimise them by:
- not buying plastic products. Choose alternative goods made from wood and only natural materials
- avoiding plastic packaged products. Choose paper and cardboard wrapped goods only
- buying nothing but natural clothing (cotton, wool etc).
Where do microplastics come from?
Microplastics are often invisible to the naked eye, and as previously stated, they run directly into the sewage system from the washing machine, sink, and bathroom drain.
They are not filtered out by wastewater treatment systems.
Tyre abrasion is responsible for up to 68,000 tonnes of microplastic contamination each year, 7,000 to 19,000 of which end up in UK waterways.
In a word, this is how most microplastics enter the seas and contribute to the whirling ‘plastic soup.'
Microplastics are absorbed or eaten by sea creatures, and these particles are subsequently transferred down the marine food chain. Because humans are at the top of the food chain, we swallow microplastics as well.
Microplastics are not biodegradable and are nearly hard to remove once they reach the (marine) environment. Using microplastic-containing body washes or cosmetics puts the ocean, ourselves, and our children in danger!
Microplastics are defined as plastic particles smaller than 5mm and bigger than 1 micron (1/1000th of a millimetre) in length, and their impact as one of the most ubiquitous and persistent contaminants on the planet is just now being thoroughly investigated. Microplastics are commonly found in things such as glitter, microbeads, and fragments from bigger pieces of plastic trash, as well as clothes.
How do washing machines contribute to microplastic pollution?
Most people are aware that synthetic materials (polymers, microplastics, or plastics) are a major source of worldwide environmental degradation and contribute to species extinction. However, did you know that when we wash synthetic garments, our washing machines contribute to microplastic pollution?
Experimenters who collected wastewater from residential washing machines discovered that a single garment can yield more than 1900 fibres every wash.
When we wash our clothes, these small synthetic fibres from our synthetic polymer garments are discharged into the waste drainage systems of washing machines.
This is estimated to produce between 2,300 and 5,900 tonnes of microplastic pollution in the UK each year.
More Ways to Reduce Microplastics
Reduce our consumption of single-use plastics (refill water bottles, buy in bulk, and buy items packaged in other materials like glass or paper). Encourage the establishment of a standardised method for analysing microplastics. Because there is no standard method for determining the quantity of microplastic in water or tissue, results from one laboratory cannot be compared to results from another.
We still don't know what effect these microplastics have on human health. However, having hard flooring, utilising more natural fibres in clothes, furniture, and homewares, and vacuuming at least weekly can all help to decrease your exposure.
Organizations throughout the globe, including those responsible for the aforementioned papers or studies, are urging efforts to eliminate microplastic marine trash and more scientific study to help us comprehend microplastics. These objectives are actively supported by the plastics industry.
Plastic particles can affect our immune system
In one study, researchers discovered a link between microplastics and brain damage in fish. Their studies show that plastic nanoparticles go up the food chain, penetrate the brain of the top consumer, and influence its behaviour, significantly altering the operation of natural ecosystems.
Another chemical present in plastic and certain food packaging, styrene, has been linked to a variety of health concerns, including nervous system difficulties, hearing loss, and cancer. According to Flaws, microplastic particles can also collect polychlorinated biphenyls (PCBs), which are connected to a variety of health concerns, including cancer, a weaker immune system, reproductive issues, and more.
In summary, those little fragments of plastic enter our systems and circulate throughout our bodies, potentially affecting our health in a variety of ways. They can have an effect on our immune system, digestive system, endocrine system, and other systems.
Media coverage of Microplastics articles: How Much Microplastic do we Consume
The mainstream media has recently picked up on stories of microscopic particles of wind-blown plastic. This significantly enhances the mobility and spread of microplastics. Utah State University scientists conducted studies and discovered that approximately 1,000 tonnes of microplastic particles fall on America's National Parks and other wilderness regions each year.
The media helps people realise the scope of the problem by citing the annual release of 41 million tonnes of plastic into the oceans. Most readers will find this meaningless, but knowing that it correlates to 100,000 garbage truckloads will help them comprehend. Floating plastic continents in multiple oceans, plastic bag-eating turtles, and dead whales with plastic garbage stomachs are just a few of the recent findings that have attracted a lot of media attention.
“When we take a bite of an apple, we are almost definitely eating microplastics along with it,” explains Sion Chen, a Greenpeace media campaigner.
Are litter, plastic and microplastic quantities increasing in the ocean?
Yes. The amount of litter, plastic, microplastic, and even nanoplastics in the water is growing.
Only biological materials decay and vanish; the rest do not rot and degrade slowly over hundreds of years. However much microplastic do we consume now will continue to rise in the future.
Tiny Robots Could Clean Up Microplastic Pollution
Microplastics are extremely small and very hard to clean up. The main cause of ocean pollution, they are extremely small pieces of plastic created by the breakdown of larger plastic waste. The minute pieces are often hard to see with the naked eye. In theory, at some time in the future tiny robots could be programmed to find them and collect them and that might even be financed by the value of the plastic which could then be processed and recycled.
This might occur, but not for a long time. No current technology could do this.
Microplastics as contaminants in the marine environment
Microplastic pollution of the marine environment has been an increasing concern since the 1940s, when industrial manufacture of plastics started. The mechanisms by which microplastics enter the marine environment can only be measured with any precision if procedures for evaluating methods for detecting microplastics in the marine environment have been agreed upon.
Only then would it be feasible to analyse geographical and temporal patterns in microplastic abundance and, as a result, debate the environmental effect of microplastic and provide potential remedies.
The Problem of Single-Use Plastics
Plastic pollution cannot be solved just via study. The usage of plastic is not the source of the problem. The underlying issue, though, is the single-use lifestyle we've gotten accustomed to.
The problem would be solved if all plastic was reused, recycled if not appropriate for reuse, and eventually burnt within a healthy circular economy. As a result, everyone who wants to help minimise the plastic problem should avoid using single-use plastic goods. Choose things that come in reusable containers and either return them or repurpose them in your house.
Microplastic Pollution: How You Can Help Solve The Problem
You can help solve the problem by voting through your buying habits. Don't buy plastic goods, and synthetic textiles, unless there is no alternative. If no alternative exists, buy the product with the least plastic.
Finally, don't drop litter. That final point about not littering might seem obvious but plenty of people who consider themselves environmentally aware have been known to leave their litter lying around.
How can I avoid eating microplastics?
Given the prevalence of microplastics in our environment, water, and food supplies, it is simply impossible to avoid consuming them. They are impossible to detect in food. You cannot determine whether or not to consume a certain dish based on what you see or taste. Making knowing how much microplastic do we consume is unanswerable.
The crucial point is that we all substantially minimise our usage of plastics in order to lessen the flow of it.
Researchers do not know how much microplastics a person can withstand or how much harm it may inflict. All we know is that ingesting microplastics can cause organ damage and leach dangerous substances like pesticides into our systems.
Current high-end estimates of microplastic particle ingestion vary from 52,000 to billions of particles per year. However, the food categories studied by most researchers account for a very minor portion of the normal adult's diet. There are numerous food kinds that we consume that have not yet been researched, such as cereals, making it difficult to gain a good picture of how much microplastics we are ingesting.
Conclusion to: What are Microplastics? How Much Microplastic do we Consume?
Microplastics are making their way into our waterways and soil. They get rubbed off vehicle tyres and blow around in the wind. Eventually, they end up in the oceans and hence are being consumed by all living things, including humans.

This has resulted in piles of plastic garbage in many places, particularly in urban areas, producing massive environmental challenges for terrestrial and marine ecosystems. While some plastics have stayed in big fragments in maritime settings, others have broken down into tiny bits owing to a variety of causes.
Many people are aware that plastic pollution in the ocean is a major issue. They may build up in regions of the world's oceans twice the size of Texas, and microplastics in particular (plastics that break down into bits smaller than 5 mm) can, according to many scientists, kill marine species if consumed.
However, microplastic contamination of the human food chain is caused via absorption by marine creatures including fish. Plasticizers can also absorb other organic contaminants, although the long-term consequences are unknown. So, we are still begging the question of how much microplastic do we consume and will have to wait a while longer for the answer.
