Many herbicides can exist in the atmosphere as both a droplet and evaporated vapor. Therefore, methods to assess personal exposures to herbicides samplers must be developed to optimize capture of both droplet and vapor phases. This webinar will describe the qualities of two such samplers. Measurements taken in both the lab and field will be presented to demonstrate sampler qualities and to detail the considerations needed to properly assess herbicide exposures.
At the completion of this activity, the learner will be able to:
Describe the concept of an inhalable sampler
Distinguish between two herbicide samplers in terms of their droplet collection efficiency
Dr. Patrick O’Shaughnessy joined the faculty at the University of Iowa in 1997, where he holds the rank of Professor in the department of Occupational and Environmental Health. He is a member of the Industrial Hygiene faculty in that department and is the Director of the NIOSH ERC at the University of Iowa, the Heartland Center for Occupational Health and Safety. Dr. O’Shaughnessy is a recognized scholar in the field of aerosol physics, respirator performance, and human exposure assessment applied to occupational and environmental health concerns.
The Center for Occupational and Environmental Health designates this activity for a maximum of 1.0 Contact Hour. Participants should claim only the credit commensurate with the extent of their participation.
Certificates of Completion will be available to webinar participants who are present for the complete, live webinar, and logged in with their registered email address. Call-in attendees are not eligible for certificates at this time - Please download the Zoom app to log in via email on your smartphone whenever possible.
