Introduction to microplastic research: How we measure micro- and nano-plastics

It is easy to understand how microplastics are small when compared to Daphnia and Bacteria! How microplastics are generated, how much of them exist in the world, and how to measure them... Researchers will explain the frontiers of plastics research in an easy-to-understand manner, including the latest research results on nanoplastics, which are even finer than microplastics. 【Contents】 00:00 Introduction 00:39 What are microplastics? 02:28 How much microplastic is present? 03:07 Determine the number and size of microplastics 04:41 Analyze the material of microplastics 06:22 Much smaller!
