The paper investigates the presence and potential effects of microplastics in drinking water. The paper focuses on the ways in which microplastics enter drinking water sources, including the purification and distribution processes, and how this contaminant can affect human health. The first part points out that microplastics are becoming ubiquitous in the environment and can be found in a variety of waters, including drinking tap water and bottled water. Potential risks for human health are indicated with regard to the intake of microplastics through drinking water. Methods for removing microplastics from drinking water are then considered, and strategies for controlling the source of pollution are proposed. The paper emphasizes the need for further research in order to better understand the effects of microplastics on human health and to develop effective methods for purifying drinking water from this pollutant. The conclusion of the paper emphasizes the importance of understanding the presence of microplastics in drinking water and the need to take measures to reduce the contamination of drinking water with this material and ensure the safety of water for human consumption.
