Boiling water and filtering reduces plastic particles by 90%: Study

Plastic particles are commonly found in drinking water. According to research, plastic particles can be greatly reduced by boiling the water and filtering it. (Schematic diagram, pixabay)

Plastic particles (also known as microplastics) are ubiquitous. People cannot live without plastic products in their daily lives. They often eat plastic particles through drinking water, and plastic particles are in the ocean, atmosphere, drinking water and food. The existence of environmental pollutants is becoming more and more common, and people are often exposed to such environmental pollutants. However, the latest experiments have found that just boiling the water and filtering it with filter paper can effectively reduce microplastics by 90%.

According to the “Medical News Daily” (MNT) report, the National Oceanic and Atmospheric Administration (NOAA), the United Nations Environment Program (UNEP) and the European Chemicals Agency define plastic particles as less than 5 millimeters (mm) in length and Particles that are insoluble in water.

A study published in the journal Nature in 2020 showed that plastic particles have a negative impact on human intestinal flora. In daily life, although the number of plastic particles in tap water can be reduced through filtration systems, researchers have recently discovered that there is a simple action that can significantly reduce plastic particles.

A new study in the journal Environmental Science and Technology Letters shows that by boiling water and filtering it with coffee filters, plastic particles can be reduced by up to 90%. Researchers sampled hard water in Guangzhou and added different proportions in the experiment After boiling the nanoplastics and microplastics for 5 minutes, it was found that because hard water contains minerals, a crystal structure of calcium carbonate is formed after boiling, and the particles of nanoplastics and microplastics are coated in it. These coated particles Coated plastic particles may accumulate over time. Filtering water through a coffee filter can remove the coated plastic particles.
