Plastic pollution is a growing threat to human health and the environment. Microplastics, tiny plastic particles, have been detected in drinking water and food, with unknown potential health and ecosystem effects. These particles are formed when plastics break down into smaller bits and can be found in water sources, including bottled water, which may contain tens of thousands of plastic fragments per litre. The health risks associated with microplastics are influenced by their physicochemical properties and the contaminants adsorbed onto their surfaces. While the full ramifications of microplastic ingestion are not yet known, studies suggest that exposure may contribute to health issues such as altered metabolism, disrupted immunity, neurotoxicity, and an increased risk of cancer. Reducing exposure to microplastics involves minimising the use of single-use plastics and plastic packaging, as well as improving wastewater management and treatment processes.

What You'll Learn
Microplastics in drinking water
Plastic pollution is a pressing issue that has gained more awareness in recent years. Plastics degrade over time, breaking into smaller pieces known as microplastics, which are less than 5mm in size and often require a microscope to be seen. These microplastics have been found in various ecosystems, including our drinking water. A global study on tap water samples revealed that up to 83% contained microplastic fibres.
Microplastics enter our waterways through various means. Plastic bottles, food packaging, and plastic bags are commonly found in rivers and oceans, contributing to the presence of microplastics in freshwater sources. Additionally, microbeads from wash-off cosmetics, cleansers, and toothpaste, as well as microfibers from clothing made of synthetic materials, enter our sewer systems and eventually our water supply.
The presence of microplastics in drinking water has raised concerns about potential health risks. While the human health effects are still not fully understood, animal studies suggest that ingested or inhaled microplastics may accumulate and induce an immune response, leading to particle toxicity. There is also a risk of chemical toxicity due to the leaching of plastic-associated chemicals and adsorbed toxins. Microplastics can accumulate antimicrobial-resistant pathogens, potentially impacting human health if present in drinking water.
To address this issue, there is a growing focus on improving the quality of studies examining microplastic occurrence in drinking water. Standardized methods for sampling, extraction, and detection are necessary to enhance data reliability and enable comprehensive risk assessments. Additionally, reducing plastic use and minimizing plastic contact with food and water are recommended to lower exposure to microplastics.

Microplastics in bottled water
Microplastics are plastic fragments that are less than 5mm in size and usually require a microscope to be seen. They are formed when plastics break down over time and can be found in soil, rain, cosmetics, produce, and more. Microplastics have also been detected in drinking water, with studies finding that a liter of bottled water may contain about 240,000 tiny pieces of plastic, 90% of which are nanoplastics. These small plastic particles are able to enter the body's cells and tissues and have been found in human blood, lungs, gut, feces, and reproductive tissues.
The presence of microplastics in bottled water has raised concerns about potential health implications. While the health effects of ingesting microplastics are still unknown, studies suggest that they may accumulate in the body and cause particle toxicity by inducing an immune response. In addition, microplastics in water can provide a hospitable place for microbes to grow, including pathogens, which can become antimicrobial resistant.
The detection of microplastics in bottled water has been made possible through the development of new imaging techniques, such as a modified version of Raman spectroscopy, which uses lasers to analyze the chemical composition of cells. However, there is currently a lack of standardized methods for measuring and quantifying nanoplastics, and more research is needed to fully understand their potential health impacts.
Despite the concerns surrounding microplastics in bottled water, many people still rely on single-use plastic bottles for drinking water. According to a survey, 33% of US adults drink bottled water daily, and 23% drink it a few times a week. The convenience and accessibility of bottled water may contribute to its continued use, even as concerns about plastic pollution and microplastics grow.
To reduce exposure to microplastics in drinking water, individuals can consider installing water filters or using loose-leaf tea instead of tea bags, as synthetic materials in home water filters and tea bags may also be a source of microplastics.

Microplastics in tap water
Microplastics are present in tap water, with 95% of US tap water containing microplastics. A study by Sherri Mason, a Penn State researcher, found an average of 5.5 plastic particles per litre of tap water. Another study on tap water samples found that up to 83% of these contained microplastic fibres.
Microplastics are bits of plastic less than 5mm in size, smaller than a popcorn kernel, and usually require a microscope to be seen. They are found in every ecosystem on Earth and consist of microbeads, microfibres, and broken-down pieces of plastic. Microbeads are tiny abrasives, usually polyethylene, found in wash-off cosmetics, cleansers, and toothpaste. In 2015, the US banned the use of microbeads in cosmetics and toothpaste, but they continue to be used and found in waterways. Microfibres are tiny pieces of threads and fibres that break off clothing. Clothing made from plastic (nylon, polyester, rayon, acrylic, and spandex) sheds microfibres with every wash. These microfibres and microbeads go down the drain into sewer systems, and wastewater treatment plants are not designed to remove all particles.
Microplastics in the environment can leach chemicals and attract and concentrate heavy metals and organic pollutants dissolved in the water, such as polychlorinated biphenyls (PCBs). Plastic debris can accumulate pollutants up to 1,000,000 times the levels found in seawater, according to the National Oceanic and Atmospheric Administration (NOAA). This chemical adsorption and bioaccumulation is a significant concern. Microplastics are consumed by aquatic life and bioaccumulate in the food chain, travelling from filter feeders to apex predators.
The presence of microplastics in drinking water has triggered discussions on possible implications for human health. Studies suggest that microplastics may accumulate and cause particle toxicity by inducing an immune response if inhaled or ingested. Chemical toxicity could also occur due to the leaching of plastic-associated chemicals and adsorbed toxins. However, the human health effects are still unknown, and current exposure levels, including through drinking water, need to be assessed.

Microplastics in freshwater
Plastic materials have generated huge societal benefits, but the 'plastic age' has its downsides. One significant concern is the accumulation of plastics in the aquatic environment. Microplastics, fragments smaller than 5mm, are of particular concern because they can be ingested throughout the food web more readily than larger particles.
Microplastics have been detected in drinking water and drinking water sources, triggering discussions on the possible health implications for humans. A global study on tap water samples found that up to 83% contained microplastic fibres. Microplastics are also present in bottled water, entering from water distribution systems. Synthetic clothing, cosmetics, and plastic shopping bags are all sources of microplastics that can end up in our water systems.
Microplastics are frequently present in freshwaters, and their number concentrations can span ten orders of magnitude (1 × 10−2 to 108 #/m3) across individual samples and water types. The largest portion of microplastics in freshwater systems comes from wastewater treatment plants. They can enter freshwater through treated and untreated sewage effluent, surface runoff, air deposition, industrial effluent, and tainted plastic trash.
The continuous increase in synthetic plastic production and poor management of plastic waste have led to a tremendous increase in dumping into our aqueous environment. Microplastics can stay in freshwater environments and accumulate in isolated and static water bodies. They can also be stored in the tissue of organisms and cause physical damage. The health effects of microplastic exposure via ingestion or inhalation are still unknown, but animal studies suggest they may accumulate and cause particle toxicity.

Health effects of microplastics
Microplastics are plastic fragments and particles with a diameter of less than 5 mm. They are called nanoplastics when the diameter is less than 1 μm. Humans are exposed to microplastics through direct ingestion, direct contact, and inhalation. They are present in drinking water, bottled water, seafood, salt, sugar, tea bags, milk, and so on.
The health effects of microplastics are still being studied, and there are many unknowns. However, some studies have indicated potential adverse effects on human health. For example, studies in cell cultures, marine wildlife, and animal models have shown that microplastics can cause oxidative damage, DNA damage, and changes in gene activity, which are known risk factors for cancer development. Microplastics have also been linked to reproductive issues in animal studies, with effects such as reduced sperm count and quality, ovarian scarring, and metabolic disorders in offspring.
In addition, microplastics have been detected in almost every part of the human body, including breast milk, the placenta, testicles, hearts, livers, and kidneys. Some studies have associated microplastics with poor health outcomes, including cardiovascular disease and low male fertility. The chemicals often found in plastics are known to cause various health problems, including cancers, metabolic disorders, attention deficit/hyperactivity disorder, and fertility issues.
While the full extent of the health impacts of microplastics is not yet known, there is growing concern among scientists and clinicians about their potential effects on human health. More research is needed to thoroughly identify and analyze the potential impact of microplastics on human health and the environment.
