Indoor Air sciences CSMI Practice Exam

Which age group is most susceptible to indoor air quality issues?

1. 13-19 years old

2. All age groups are equally susceptible

3. 20-39 years old

4. 0-1 years old

The correct answer is: 0-1 years old

The age group that is most susceptible to indoor air quality issues is infants, specifically those aged 0-1 years old. This vulnerability stems from several factors. Infants have developing respiratory systems, and their lungs are more sensitive to pollutants. They breathe at a higher rate relative to their body size, which means they intake more air (and potential contaminants) compared to older children or adults. Additionally, infants spend a significant amount of time indoors, often in confined spaces where pollutants can accumulate. Their immune systems are also still developing, making them less capable of defending against harmful substances found in indoor air quality issues such as mold, dust mites, volatile organic compounds (VOCs), and other irritants. By understanding these characteristics, it becomes clear why infants are particularly at risk regarding indoor air quality, leading to potential respiratory problems or other health concerns. The other age groups either do not have the same level of sensitivity or exposure characteristics that place them at such a high risk as infants. For instance, older children and adults have more developed respiratory systems and can often tolerate lower levels of pollutants more effectively.
