Which condition can elevate the release of VOCs significantly?

High air temperatures can significantly elevate the release of volatile organic compounds (VOCs) from various sources, including paints, cleaning products, and building materials. When temperatures rise, the kinetic energy of molecules increases, leading to a higher rate of evaporation and off-gassing from these materials. This can be particularly noticeable in indoor environments where heating systems or sunshine can cause temperature spikes.

Understanding the relationship between temperature and VOC emissions is crucial for managing indoor air quality, especially in spaces where VOC sources are present. By recognizing that high temperatures can exacerbate the presence of VOCs, steps can be taken to mitigate their impact, such as controlling indoor temperatures or increasing ventilation to dilute the concentration of these compounds.
