Plastic pollution is an increasingly pressing issue, with plastic waste entering water sources through littering, poor waste management, stormwater runoff, and more. Microplastics, a general term for plastic particles 5mm and smaller, have been detected in tap water worldwide, with 83% of samples from more than a dozen nations found to be contaminated. The US had the highest contamination rate at 94%. While the health implications of consuming microplastics are still being studied, there are concerns about the potential toxicity and related metabolic diseases, cancer, and reproductive problems. The presence of microplastics in tap water highlights the need for further research and urgent action to address plastic pollution and its potential impact on human health and the environment.

What You'll Learn
Microplastics are found in tap water worldwide
Microplastics are indeed found in tap water worldwide. A study by Orb Media, which analysed tap water samples from more than a dozen nations, found that 83% of the samples were contaminated with plastic fibres. The United States had the highest contamination rate at 94%, with plastic fibres found in tap water sampled at sites including Congress buildings, the US Environmental Protection Agency's headquarters, and Trump Tower in New York.
The presence of microplastics in drinking water has raised concerns for public health due to the possible toxicity associated with their polymeric composition, additives, and other compounds or microorganisms adsorbed on their surfaces. These plastic particles can attract bacteria found in sewage and have been shown to contain and absorb toxic chemicals, which are then released in the body. Research on wild animals has shown that microplastics are present in a third of fish caught in the UK, and studies in Germany have found plastic fibres and fragments in all of the 24 beer brands they tested, as well as in honey and sugar.
The scale of global microplastic contamination is vast, with microplastics found in the air, water, soil, food, and consumer products. They enter water sources through littering, poor waste management, stormwater runoff, fishing vessels, cargo and cruise ships, and more. Single-use plastics are a significant contributor to this pollution, as they do not fully decompose but break down into smaller and smaller particles, forming microplastics. Microfibers from clothing made of plastic, such as nylon and polyester, also shed microfibers with every wash, which then enter sewer systems.
While wastewater treatment plants aim to remove microplastics, they are not designed to remove all particles, and current standard water treatment systems do not filter out all microplastics. As a result, microplastics can be discharged into waterways through wastewater effluent and may also remain in the sewage sludge that is applied as fertiliser on agricultural fields. The World Health Organization has acknowledged the presence of microplastics in drinking water, noting the diversity of sizes and chemical makeup, and scientists are actively studying the health effects of microplastics on humans and animals.

Microplastics can attract harmful bacteria
Plastic fibres have been found in tap water across the world. Tests show that billions of people globally are drinking water contaminated by plastic particles, with 83% of samples found to be polluted. The US had the highest contamination rate, at 94%.
Microplastics are known to contain and absorb toxic chemicals, and research on wild animals shows that these chemicals are released in the body. Studies have shown that microplastics can attract harmful bacteria found in sewage. Prof Richard Thompson, at Plymouth University, UK, told Orb:
> It became clear very early on that the plastic would release those chemicals and that actually, the conditions in the gut would facilitate really quite rapid release.
His research has shown that microplastics are found in a third of fish caught in the UK. Furthermore, studies in Germany found fibres and fragments in all of the 24 beer brands they tested, as well as in honey and sugar.
The ubiquity of microplastics in the environment, combined with preliminary findings from human cell and animal studies over the past decade, have led to urgent calls for more research and regulation. Scientists are studying the impacts on both animal and human health.

Plastic pollution is rampant in bottled water
Plastic pollution is an urgent global crisis. While the public has become more aware of the issue in recent years, plastic pollution continues to be rampant in bottled water.
A study by Sherri Mason, a Penn State researcher, found an average of 325 plastic particles per litre of bottled water, compared to 5.5 plastic particles per litre of tap water. Another study by researchers from Columbia University and Rutgers University found at least 240,000 plastic particles in a litre of bottled water, with 90% of these particles being nanoplastics. These tiny plastic particles are smaller than a sesame seed and cannot be seen with the naked eye.
The high levels of plastic particles in bottled water can be attributed to the use of plastic pipes, water storage, and treatment equipment, as well as environmental pollution. Plastic water bottles themselves are also a significant source of plastic pollution. Single-use plastic bottles contain PFAS, a class of chemicals that are harmful to human and environmental health. Additionally, plastic bottles can leach toxic chemicals when exposed to warm environments, sunlight, or reuse.
The potential health effects of consuming these tiny plastic particles are still unknown, but they have been found in human blood, lungs, gut, feces, and reproductive tissues. Plastic pollution in bottled water is not just a health concern but also contributes to the growing environmental crisis caused by plastic waste.
To address this issue, it is essential to reduce plastic use and transition to plastic-free alternatives, such as ceramic, glass, or stainless steel reusable water bottles. Banning plastic bottles from schools and other institutions can also help protect children's health and educate the next generation about the importance of reducing plastic pollution.

Microplastics are released from textiles and clothing
Microplastics are indeed present in tap water, with 83% of samples from more than a dozen nations found to be contaminated with plastic fibres. The US had the highest contamination rate, at 94%.
Textiles made from natural fibres also shed microfibres, although these are not considered microplastics. The release of microfibres is especially high during the first few washes of new clothes, so the fast fashion industry, with its rapid turnover of garments, contributes significantly to microplastic pollution. In addition, the various materials and accessories used in clothing and textile products, such as prints, coatings, buttons, and glitter, can be sources of microplastics.
The textile industry's role in microplastic pollution is a growing concern. Studies have shown that microplastics are present in the air, soil, and water, and can be ingested by humans and animals, potentially leading to serious health problems. To reduce microplastic pollution, it is recommended that consumers prioritise the purchase of natural fibres, which require less washing and do not release microplastics into the environment. Policies supporting reductions in synthetic textile production and consumption, as well as taxes on virgin plastic manufacturing, are also encouraged.

Microplastics can cause adverse health effects
Microplastics are a serious environmental concern, and their potential health hazards have been a growing worry. While the exact impact of microplastics on human health is still unclear, research has indicated several adverse health effects.
Firstly, microplastics can cause endocrine disruption by interfering with the production, release, transport, metabolism, and elimination of hormones. This can lead to various endocrine disorders, including metabolic disorders, developmental disorders, and reproductive issues such as infertility, miscarriage, and congenital malformations. The presence of endocrine disruptors in plastic polymers further exacerbates this problem, with potential links to cancers and reproductive system disorders.
Secondly, microplastics have been found to impact neural development. Studies have shown that exposure to microplastics can inhibit acetylcholinesterase (AchE) activity, increase lipid oxidation in the brain, and cause neurotoxicity. This can lead to abnormal behaviour in various organisms and potentially impact human neurological function.
Additionally, microplastics can carry and release toxic chemicals and pathogens. They have been found to absorb harmful substances such as bisphenol A and heavy metals, which can then be released into the body upon ingestion. This is particularly concerning as microplastics have been detected in seafood, tap water, and even bottled water, leading to human exposure through multiple routes.
Furthermore, the impact of microplastics on the immune system warrants attention. Animal studies have indicated that chronic exposure to microplastics can induce inflammation and homeostasis changes. While the specific effects on humans require further research, initial studies on human lung cells suggest that microplastics can activate the innate immune response.
The complex nature of microplastics, with varying sizes, shapes, and chemical compositions, makes assessing their health risks challenging. However, the available evidence suggests that microplastics have the potential to cause adverse health effects, and further comprehensive research is necessary to fully understand their impact on human health.
