Studium mikroplastů v pitných vodách

Abstract

Increasing global production of plastic materials, along with inadequate plastic waste management and external factors, leads to the formation of microplastics. These microplastics subsequently appear in various components of the environment. Due to the lack of scientific information on this issue, it is essential to address this problem thoroughly. This dissertation focuses on the determination of microplastics in drinking water collected from the water supply network at various locations in Moravia and Silesia. During two sampling campaigns, a total of 58 drinking water samples were analyzed, representing a complete analysis of 580 selected particles. Fourier-transform infrared microspectroscopy was used to identify the material. The study also employed procedures to prevent sample contamination, which proved effective. Analysis confirmed the presence of 196 microplastics in total. In the first campaign, fibers and transparent-colored microplastics were dominant, while in the second campaign, fragments and blue-colored microplastics prevailed. All results were statistically evaluated, and the average daily intake of microplastics through drinking water was determined. This work provides valuable information for the analysis of microplastics in drinking water, as the number of studies on this topic is significantly lower compared to other types of water.
