Summary
Microplastics, originating from various sources like plastic packaging and synthetic textiles, contaminate tap water and pose risks to human health and the environment.
- Sources include plastic packaging, synthetic textiles, personal care products, and tire wear.
- Impact on the environment includes marine ecosystem disruption and alteration of water quality.
- Human health risks include ingestion of toxic chemicals and potential health issues.
Microplastics are small plastic pieces that are now a widespread and increasing issue in our tap water. These particles can be from everything from personal care products to clothes to plastics. Microplastics aren’t just harmful to human health, they are toxic to the environment as well, poisoning water and even reaching the food supply. If we want to stay healthy and green, we should be doing all we can to eliminate microplastics in tap water, and learn how to clean those particles out of our water supply.
What are microplastics and how do they impact the environment and human health?
Microplastics are tiny plastic particles that are less than 5 millimeters in size. They can come in various forms, including fragments, fibers, and beads. Microplastics are a growing environmental concern due to their widespread presence and potential impacts on the environment and human health.
Sources of Microplastics:
- Plastic Packaging: Plastic packaging materials, such as water bottles and packaging films, can break down into microplastics over time.
- Synthetic Textiles: Synthetic textiles, such as polyester and nylon, can shed microfibers during washing, which can then enter the water supply.
- Personal Care Products: Personal care products, such as exfoliating scrubs and toothpaste, can contain microbeads that can enter the water supply.
- Tire and Roadwear: Microplastics can also result from the wear and tear of tires and roads, which can break down into small particles and enter the water supply.
Effects on the Environment and Human Health:
- Marine Ecosystems: Microplastics can have significant impacts on marine ecosystems, including the entanglement and ingestion of marine life, and the transfer of toxic chemicals up the food chain.
- Water Quality: Microplastics can degrade water quality by absorbing and releasing pollutants and by altering the balance of species in aquatic ecosystems.
- Human Health: The effects of microplastics on human health are not yet fully understood, but there are concerns about the potential for microplastics to transfer toxic chemicals and pathogens to humans through the food chain.
The Role of Tap Water in Microplastics Contamination
The water from taps is one of the most commonly contaminated with microplastics because microplastics can get into the water supply by any number of means including leaching from plastic pipes and runoff from plastic waste. When it gets into our water supply, microplastics end up in our tap water, in our bottled water, and in the food we eat: microplastics have been discovered in many seafood.
It is still unknown what the impacts of microplastics in tap water will be, but research has demonstrated that they release chemicals that can be lethal to people when they drink it. That can be caused by many health issues such as reproductive and developmental disorders, cancers and endocrine disruption. What’s more, microplastics can block water filters, rendering it harder to filter water and other waste.
Microplastics in Our Oceans
Microplastics are not just a problem in tap water, they’re a problem in the oceans, and they’re devastating marine life and ocean ecosystems. Fish and other marine animals will consume microplastics, causing digestive issues and more. Second, microplastics also draw toxic chemicals from the water (like DDT and PCBs) and, once in the bodies of marine animals, these toxic chemicals are transported into the food chain where they may harm humans.
It is not known exactly what microplastics do to ocean life but researchers have observed how they alter the food web, and the ecology of the marine environment. This could have ripple effects across the whole ecosystem, with some species extinction and biodiversity declines inevitable.
The Cycle of Microplastics
The environment continues to struggle with microplastics, which never biodegrade, but rather degrade into ever-smaller pieces. They can get into the water system in various ways, from leaching from plastic pipes and plastic waste run-off, and after they’re in the water, they can be swept in by ocean currents and stored at remote locations such as the deep sea and the polar regions.
The flow of microplastics from land to water and back again underscores how much our planet is interdependent, and that we need to solve the problem holistically. We should minimize plastics waste from land and have a better waste management to keep microplastics out of water and ocean.
The Importance of Filtering Tap Water
Filtering your tap water is one way to prevent yourself from microplastics and other pollutants. There are various techniques to purify drinking water of microplastics, such as activated carbon, reverse osmosis and ceramic filters. Remember to select a water filter that has been specifically created to get rid of microplastics as not all filters will remove these microscopic particles.
But other than tap water filtering, there are other ways to lower the number of microplastics in the water supply: for example, by using less single-use plastic products, recycling plastic materials and giving back to businesses who reduce plastic pollution.
What are the impacts of microplastics on the food chain?
The reason why you filter tap water is because we need to filter it out, and clean away contaminants such as microplastics, to make sure the water we drink is clean and free of contaminants. A few techniques to clean drinking water of microplastics are:
Point-of-Use Filters: Point-of-use filters (pitcher filters, faucet filters) will clean tap water of microplastics. These filters usually consist of activated carbon, ceramic, or mesh material that removes microplastics and contaminants.
Reverse Osmosis: reverse osmosis filters the water using semi-permeable membrane to remove contaminants. It’s a process that can effectively purify tap water of microplastics.
Distillation: Distillation evaporates water by heat and distills the vapour to make purified water. Microplastics and other contaminants in the tap water can be successfully removed by distillation.
Carbon Filters: Carbon filters like activated carbon filters are excellent to remove microplastics and other contaminants from tap water. These filters are activated carbon filters which absorb pollutants and clog the filter.
The Future of Microplastics
This will be the future of microplastics, and what governments, businesses and individuals do about it will determine the way forward. To stave off contamination, single-use plastics must be reduced, waste should be properly managed, and the plastic pollution must be tackled by companies. Further development and research of new materials (for example, biodegradable plastics) could help lessen the plastic waste generated.
Governments can take action against microplastics by enforcing laws and regulations for the production and disposal of plastic products, as well as funding research and development of alternative materials. Companies can do more too, by decreasing the amount of plastic waste generated by their business and funding research and development of alternatives.
Raising Awareness About Microplastics
Announcing awareness on the microplastics problem is one way to help tackle this growing issue and one such means is school water testing services. Everyone from governments to businesses to citizens can all help educate about the risks of microplastics and how to minimise exposure and avoid contamination by advertising for school water testing services. There is also more individuals can do their part, such as lessening their personal use of single-use plastic products (eg, water bottles, plastic bags) and disposing of plastic materials in the right manner. With just a small tweak, carrying a reusable water bottle and grocery bag can go a long way to helping curb plastics waste and reduce the introduction of microplastics into the environment, with school water testing services in place.
