Prior to accessing your first module in the Occupational and Nanotechnology Health and Safety series, we need you to complete a short survey. This information will satisfy our funding requirements and tell us who is interested in learning about occupational and nanotechnology health and safety. Once you have completed and submitted the survey, you have access to all the modules without repeating the survey. There are 19 modules in the series. You may take these modules in sequence or at your own discretion. Thank you for your interest in the METPHAST Modules.
Importance of Particle Size
(This module is one of 5 units comprising the first section of METPHAST: Introduction to Occupational Hygiene. There are 15 modules on Nanotechnology Health and Safety, as well. See the section "Additional Information" for more details about these modules.)
This module will address the importance of particle size and consider factors including relaxation time and implications, diffusion, lung deposition, filtration, coagulation, and evaporation/condensation.
By the end of this module, learners should be able to:
- Describe the forces that cause particles to move in air
- Predict the behavior of a particle given its size
- Connect the importance of particle size on development of adverse health effects
- Explain the rationale for measuring personal exposure with health-revelant size criteria
