Which of the following contaminants is commonly associated with indoor air quality issues?

  1. Carbon dioxide

  2. Ozone

  3. Formaldehyde

  4. Radon

The correct answer is: Formaldehyde

Formaldehyde is a volatile organic compound (VOC) that is commonly associated with indoor air quality issues due to its widespread use and potential health effects. It is found in a variety of household products, including pressed wood products, furniture, textiles, and building materials. When these items off-gas, they release formaldehyde into the indoor environment, leading to elevated concentrations that can cause various health problems. Exposure to formaldehyde has been linked to respiratory issues, eye irritation, skin irritation, and even long-term effects such as cancer. This connection between formaldehyde and adverse health impacts substantiates why it is considered a significant indoor air contaminant that warrants attention and mitigation measures in indoor environments. While other contaminants listed can also impact indoor air quality, formaldehyde's prevalence in household products and its specific health risks underline its significance in discussions about indoor air quality.
