Tutoring Subject: Environmental and health impacts of nanoparticles

Abstract:

Environmental Nanoscience is an interdisciplinary course designed to explore the fundamental principles and applications of nanoscience in addressing critical environmental challenges. The course covers the unique properties and behaviors of nanoparticles (NPs) in natural and engineered environments, emphasizing their roles in water purification, waste management, and environmental remediation. Key topics include the formation, abundance, and significance of natural NPs, the environmental implications of anthropogenic NPs, and advanced techniques for detecting and characterizing NPs in complex media such as soils, sediments, water, and air. Students will also delve into the geochemical classification and interactions of NPs, exploring how they affect geological and environmental processes, including pollution and contaminant transport.

This course further examines the health implications of NP exposure, focusing on air quality and the toxicity of particulate matter. Students will be introduced to advanced lab and synchrotron techniques, such as scattering, spectroscopy, and electron microscopy, for studyingNPs. Through a combination of lectures, projects, and interactive assignments, students will gain a theoretical understanding and practical knowledge in NPs analysis and environmental and health impact assessment. By the end of the course, students will be equipped to evaluate the impacts of NPs on soil, water, and air quality, as well as their potential health risks, making them well-prepared to contribute to the field of environmental nanoscience.
