Comparison of chemical reactions between cyclone and filter for collection of PM2.5

The project focuses on studying the physicochemical characteristics of cyclone-collected PM2.5 in urban environments. Utilizing advanced techniques like Energy-dispersive X-ray fluorescence (EDXRF) and X-ray absorption fine structure spectroscopy (XAFS), the research aims to provide insights into the composition of fine particulate matter, including metals with varying toxicities such as chromium. The innovative methodology involves cyclonic separation for PM2.5 collection, eliminating traditional filters and minimizing contamination. The project includes a comprehensive multi-day sampling survey, offering an opportunity to collect original data specific to Canadian urban areas. Collaborating with international partners, particularly Dr. Okuda’s team, enriches the project with a global perspective. Through this initiative, the research team anticipates advancing air quality assessment, addressing health risks, and contributing to innovative methodologies in atmospheric science research. The hands-on experience and mentorship provided are expected to catalyze the intern’s growth into an independent researcher.
