Sampling and Sample Preparation Techniques for Micro- and Nanoplastics
Summary
Scientists don't have a standard way to find and measure tiny plastic particles (microplastics) in our environment, making it hard to compare research results. This review paper examines different methods researchers use to detect these plastic particles in air, water, soil, food, and living things. Having better, consistent testing methods is important because microplastics are found throughout our environment and food chain, but we can't properly track their health effects without reliable measurement techniques.
Despite constant concern about micro- and nanoplastics, the absence of a standard extraction and quantifying protocol results in a lack of data harmonization, making a comparison of the available information limited and impractical. Consequently, it is essential to delve into the essential techniques for sampling and extracting micro- and nanoplastics from different environmental matrices such as air, water, ice, soil, sediment, food articles, and plant and animal tissues. In this sense, the present chapter will examine collaborative efforts and research gaps that continue to shape the methodology used to isolate and extract micro- and nanoplastics.
