Perspectives from the Field: Results from a U.S. Exposure Assessment and Epidemilogical Study on Carbon Nanotube and Nanofiber Workers
August 25, 2020
2:00–2:30 PM Eastern Daylight Time



Carbon nanotubes and nanofibers (CNT/F) have offered the potential for technological breakthroughs in biomedicine, electronics, as well as high-performance intermediates such as coatings and composites. Since the production and commercialization of CNT/F over the past 10-15 years, concerns have been raised about possible human health effects due to their pulmonary and cardiovascular toxicity in animal models and through analogy with other fibrous structures. Animal studies have indicated that inhlation of certain types of CNT/F may induce localized inflammation, cytotoxicity, interstitial fibrosis, mutagenesis, and may have the potential to promote lung tumorigenesis. Howerver, there has been limited evidence of human health effects due to exposure. This presentation will discuss the exposure assessment and epidemiologic results from the first cross-sectional study on workers exposed to CNT/F with the U.S. and compare them to other international cross-sectional exposure and epidemiologic studies.   

Learning Objectives

After participating in this webinar, attendees will:

  • Learn what carbon nanotubes and nanofibers are and their uses in industry.
  • Learn what are the human health concerns with CNT/F and relevant occupational exposure limits.
  • Learn what levels of exposure are currently occruing in the US.
  • Learn what potential health effects may be occurring at the US levels of exposure.
  • Learn how the US levels of exposure and epidemiologic results compare to other international studies.

This webinar may also qualify for CSP recertification points. See the BCSP website (bcsp.org) for details. Participants seeking confirmation of attendance for the webinar from ACGIH® must attend the live webinar or view the archive and submit a final exam and evaluation. Certificates of Completion will be issued in a timely manner after receipt and completion of these items.

What is an ACGIH® Webinar?

ACGIH® is dedicated to providing quality, scientific, educational events. One method of doing this is to offer distance-learning webinars. A webinar, short for Web-based seminar, is a presentation, lecture, or seminar that is transmitted over the Internet. A key feature of a webinar is its interactive elements — the ability to give, receive and discuss information. Webinars are as effective as on-site presentations without the travel expense. This ACGIH® webinar is .5 hours in duration and consists of a live presentation given via the Internet with no option for call in audio.
