Synthetic Antioxidants in Air and Dust - Predictive Relationships

Ernest N. Morial New Orleans Convention Center 

Synthetic antioxidants (SAs), such as synthetic phenolic antioxidants (SPAs), amine antioxidants (AAs), and organophosphate antioxidants (OPAs), are widely used in consumer products like plastics, textiles, and personal care items to prevent oxidative damage. However, these substances and their products, including BHT-quinone (BHT-Q) and 6-PPD-quinone (6-PPD-Q), have been associated with health issues like endocrine disruption, liver toxicity, and DNA damage. Employees in retail and office environments may be exposed to SAs by breathing indoor air and coming into contact with dust, where these chemicals tend to accumulate. Since people spend many hours at work and activities such as cleaning can disturb dust, it is important to understand how SAs in air and dust relate to each other to better assess exposure risks and enhance indoor environmental quality (IEQ) in workplaces.
