T2  - Journal of Hazardous Materials
N2  - We present a new method for investigating the oxidation and emission behavior of air-permeable materials.
Employing this method, a differentiated statement can be made about the extent to which critical volatile organic
compounds (VOCs) such as formaldehyde, acetaldehyde, and acrolein are contained in the material as impurities or
formed by thermo-oxidative degradation of the polymer matrix in the use phase. The parameters affecting methods
of VOC analysis are reviewed and considered for the developed method. The molecular mechanisms of VOC formation
are discussed. Toxicological implications of the reaction kinetics are put into context with international
guidelines and threshold levels. This new method enables manufacturers of cellular materials not only to determine
the oxidative stability of their products but also to optimize them specifically for higher durability.
Environmental Implication: Cellular materials are ubiquitous in the technosphere. They play a crucial role in
various microenvironments such as automotive interiors, building insulation, and cushioning. These materials
are susceptible to oxidative breakdown, leading to the release of formaldehyde, acetaldehyde, and acrolein. The
ecotoxicological profiles of these compounds necessitate monitoring and regulation. The absence of reproducible
and reliable analytical methods restricts research and development aimed at risk assessment and mitigation. This
work significantly enhances the toolbox for optimizing the oxidative stability of any open-cell cellular material
and evaluating these materials in terms of their temperature-dependent oxidation and emission behavior.
