What's Happening?
Researchers from Guangzhou Medical University in China have discovered a straightforward method to remove nanoplastics and microplastics (NMPs) from drinking water. The process involves boiling water and then filtering it, which can remove up to 90% of
NMPs, depending on the water's mineral content. This method is particularly effective with hard tap water, which contains more minerals like calcium carbonate. The boiling process causes these minerals to precipitate, trapping plastic particles in a crust that can be filtered out. This technique offers a practical solution for reducing human intake of NMPs, which are a growing concern due to their potential health risks.
Why It's Important?
The presence of microplastics in drinking water is a significant environmental and health concern, as these particles are pervasive and can enter the human body through consumption. The new method provides a cost-effective and accessible way for individuals to reduce their exposure to these particles, potentially mitigating health risks associated with microplastics. As wastewater treatment plants are not fully effective in removing these particles, this household method could serve as an interim solution while more comprehensive measures are developed. The widespread adoption of this practice could lead to a significant reduction in global microplastic exposure.
What's Next?
The researchers hope that the practice of boiling and filtering water will become more widespread, especially in regions where it is not already a common practice. Further research is needed to explore the long-term health impacts of microplastic exposure and to develop more effective large-scale solutions. Additionally, there may be increased advocacy for regulatory measures to address microplastic pollution at its source, including stricter controls on plastic production and waste management.
