An indoor air quality (IAQ) risk assessment evaluates a product's potential to produce adverse human health effects and sensory perception effects, such as irritation and odor. Emissions data obtained from an environmental chamber evaluation are used to predict indoor concentration levels of volatile organic compounds (VOCs), aldehydes, particles, ozone, and other potential pollutants. UL AQS has the expertise required to conduct a complete IAQ risk assessment for your product against a wide array of health-based exposure criteria.
