Development and use of a sampling and analytical method for azodicarbonamide

Area of Science:

• Occupational Health and Safety
• Polymer Chemistry
• Analytical Chemistry

Background:

• Azodicarbonamide is a widely used blowing agent in polymer foaming.
• Concerns exist regarding potential adverse health effects on workers exposed to azodicarbonamide.
• Previous assessments necessitated detailed health hazard evaluations.

Purpose of the Study:

• To assess the health hazards associated with azodicarbonamide use in industrial settings.
• To develop and validate a sampling and analytical method for airborne azodicarbonamide.
• To evaluate workplace environments for potential respiratory health risks.

Main Methods:

• Conducted two health hazard evaluations focusing on worker exposure.
• Collected environmental samples on Teflon filters for total dust and azodicarbonamide.
• Utilized high-performance liquid chromatography (HPLC) with UV detection for analysis.

Main Results:

• The developed HPLC method demonstrated sensitivity and specificity for airborne azodicarbonamide.
• Quantification of airborne azodicarbonamide concentrations was achieved.
• The study provided data to evaluate the workplace environment for respiratory hazards.

Conclusions:

• The analytical method is suitable for monitoring airborne azodicarbonamide.
• Evaluation of workplace environments can identify potential respiratory health hazards.
• Findings support the need for continued monitoring and control of occupational exposures.
