Study of Atmospheric Particulate Matter (PM) by SEM-EDS

Particulate matter (PM) with a diameter of ≤ 2.5 µm (PM2.5) from a pollution monitoring station is under investigation to characterize its structure and composition. Atmospheric PM is a significant global environmental concern due to its adverse effects on visibility and public health. Atmospheric PM exacerbates cardiovascular incidents and asthma episodes, posing a severe risk to vulnerable populations. This proposal outlines an international collaboration of Dr. Guzman aimed at collecting PM2.5 samples and identifying their mineral components using Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM-EDS). The project not only advances the scientific understanding of PM2.5 but also provides unique training to a Ph.D. graduate student in advanced analytical techniques. This training spans the interdisciplinary fields of materials science and environmental science, equipping the student with a robust skill set. Additionally, the project aims to gather preliminary data essential for a National Science Foundation (NSF) proposal. This data will support future research endeavors of researchers at the University of Kentucky and contribute to the broader scientific community’s efforts to mitigate the impacts of atmospheric particulate matter. Through this collaborative effort, the project seeks to enhance our understanding of PM2.5 and develop strategies to address its detrimental effects on both the environment and human health.
