This webinar will immerse the audience into the fascinating areas of the quantitative risk assessment.

Exposure to asbestos fibers and nanoparticles will be used to demonstrate how advanced modeling can help in the evaluation of various exposure levels.

Learn how benchmark dose modeling based on toxicological studies and epidemiological evidence can improve our knowledge about dose-response relationship and their applicability to workplace risk analysis.

Upon completion, you will be able to:

  • Compare potential health issues related to various fiber types of asbestos and carbon nanotubes
  • See what lessons can be learned from the history of asbestos studies and policies to benefit workers’ protection from emerging hazards
  • Identify dose-response relationships for complex and emerging toxicants 

Learning Objectives:    

  • Identify differences and similarities in asbestos and nanoparticles toxicity
  • Compare various models for quantitative risk assessment of respiratory hazards
  • Discuss the role of benchmark dose modeling as an important tool for human risk assessment
  • Interpret the outcome of quantitative risk assessment in terms of comparative risk acceptability
