The pervasive issue of microplastics infiltrating our bodies through food and drink is a concerning reality that needs to be addressed. Recent research has unveiled a simple and effective method of eliminating these tiny plastic particles from water, offering a potential solution to this growing problem.
A team of researchers from Guangzhou Medical University and Jinan University in China conducted experiments using both soft water and hard tap water, which contains higher mineral content. By introducing nanoplastics and microplastics (NMPs) into the water and then boiling and filtering it, the scientists were able to remove up to 90 percent of the NMPs in certain cases. The efficacy of this method varied depending on the type of water used. The key advantage of this approach is its simplicity, as it can be easily performed in any kitchen.
Impact on Different Water Types
Hard tap water, which tends to accumulate limescale due to its mineral composition, showed a higher rate of NMP removal compared to soft water. The calcium carbonate present in hard water forms a crust on plastic surfaces when heated, capturing the plastic fragments within it. Even in soft water, where calcium carbonate levels are lower, approximately a quarter of NMPs were successfully filtered out. The researchers suggest using a basic filter, such as a stainless steel mesh tea strainer, to remove any remaining plastic particles.
Previous studies have identified various types of plastic fragments, including polystyrene, polyethylene, polypropylene, and polyethylene terephthalate, in drinking water. These particles pose a risk to human health, as they are consumed daily in varying quantities. By increasing the concentration of nanoplastic particles in their experiments, the researchers demonstrated a significant reduction in their presence through boiling and filtering. This suggests that adopting the practice of drinking boiled water could potentially decrease global NMP exposure.
While boiling water may be considered a localized tradition in some regions, the research team advocates for its widespread adoption as a preventive measure against microplastic ingestion. As the harmful effects of plastic on the human body become more evident, further investigations into the benefits of boiled water are necessary. By continuing to explore this strategy, researchers aim to limit human exposure to NMPs and mitigate the potential health risks associated with microplastic consumption.
The findings of this study offer a viable solution to reducing microplastic contamination in drinking water. By leveraging the simple yet effective method of boiling and filtering water, individuals can minimize their intake of harmful plastic particles. As this research gains traction, it is essential for policymakers and the public to recognize the significance of this approach in safeguarding human health from the adverse effects of microplastics.
