Boiling drinking water has long been recognized as an effective method to combat water-borne diseases, but recent research has revealed that it may also play a crucial role in reducing exposure to microplastics. Microplastics, which are tiny pieces of plastic less than 5mm in size, have been a growing concern due to their potential harm to wildlife and possible health risks to humans. Nanoplastics, even smaller in size, are also a cause for concern.
A study published in Environmental Science & Technology Letters has shed light on the effectiveness of boiling and filtering water in reducing the amount of certain microplastics by more than 80%. The research focused on treating nano or microplastics (NMPs) found in tap water that have escaped from centralized water treatment systems.
The researchers noted that boiling water, a traditional practice in some Asian countries, has been believed to have health benefits as it can remove certain chemicals and biological substances. However, its effectiveness in removing NMPs was previously unclear. The study found that boiling water samples for five minutes and allowing them to cool resulted in an 80% reduction in microplastics such as polystyrene, polyethylene, and polypropylene in harder water.
The findings suggest that this simple boiling-water strategy could help reduce human intake of NMPs through water consumption. With microplastics being found in various sources such as meats, fish, and even in remote locations like Antarctica, the need to address this issue is becoming increasingly urgent.
A report by the World Health Organization in 2022 highlighted the global distribution of NMPs and emphasized the need for further research to understand the extent of human exposure. While the exact impact of NMPs on human health is still being studied, there is a consensus that measures should be taken to mitigate exposure to plastics in the environment.
Recent studies have also linked microplastics to potential health risks, including cardiovascular diseases. Microplastics have been found in human breast milk, blood, and various environmental samples, indicating the widespread contamination of these particles in our surroundings.
In the UK, researchers have found microplastics in every lake and river, raising concerns about the impact on wildlife. Even remote bodies of water like Loch Lomond have been found to contain plastic particles. The prevalence of microplastics in the environment underscores the importance of finding effective solutions to reduce their presence and protect human health.
In conclusion, the research on boiling water as a method to reduce exposure to microplastics highlights the need for innovative approaches to address this pressing issue. By taking simple steps like boiling and filtering water, individuals can potentially lower their intake of harmful microplastics and contribute to a healthier environment for all.
