Investigating Heavy Metal Interactions with Aged and Pristine Microplastics in Pool Water
Summary
Researchers designed an experiment to examine whether UV aging, chemical weathering, and other degradation processes alter how microplastics from pool water bind to heavy metals like lead and cadmium, using Raman spectroscopy, SEM, and UV spectroscopy to characterize the interaction products.
Microplastic (MP) accumulation has become a worldwide problem. However, it is unknown if and how they affect human health. In aquatic media, MPs serve as a vehicle for heavy metal (HM) transport. Therefore, there is a need to understand if and how these interactions are of importance to human health This research project focuses on investigating the question of whether different MP aging will result in different and/or more interactions with common HMs in a complex environment such as pool water. The experiments will be conducted with control and experimental groups of different combinations of aging methods, MPs, and HM types. The analytical tools chosen for this study are Raman Spectroscopy, Scanning Electron Microscopy (SEM), and UV Spectroscopy to identify specific MP-HM interactions according to their aging process. This project will be conducted in a controlled environment which will assist in further understanding of how MP-HM interactions affect human health.
