IAQ Investigation: Conduct The Walk-Through Step Of An IAQ I
IAQ Investigation Conduct the walk-through step of an IAQ investigation on your own home
IAQ Investigation Conduct the walk-through step of an IAQ investigation on your own home. Write a 450 word summary of your findings. Address each of the indoor air pollutants mentioned in the Unit VI Lesson (radon, mold, asbestos, CO, and airborne bacterial contaminants), and explain the potential sources and health effects of each. Conclude your investigation with what you think should be done to mitigate any problems you find. Your IAQ summary should be at least 450 words, written in essay format, follow APA style, and include at least two sources.

The quality of indoor air significantly impacts the health and well-being of residents. Conducting a thorough inspection of my home has provided valuable insights into various indoor air pollutants, namely radon, mold, asbestos, carbon monoxide (CO), and airborne bacterial contaminants. Understanding the sources and health effects of each pollutant is essential for implementing effective mitigation strategies.
Radon is a radioactive gas that originates from the natural decay of uranium in soil and rocks beneath buildings. It seeps into homes primarily through foundation cracks, construction joints, or gaps around service pipes. Radon exposure is a leading cause of lung cancer among non-smokers, making its presence in indoor environments a significant health concern (EPA, 2022). During the walk-through, I inspected the basement and foundation-entry points for potential radon entry points and observed that some cracks could permit gas infiltration. To mitigate radon levels, installing a radon mitigation system that vents radon outdoors is recommended.
Mold growth typically results from excess moisture and poor ventilation. In my home, elevated humidity levels in the bathroom and evident mold patches on bathroom walls and window sills were observed. Mold spores release airborne allergens and mycotoxins, which can cause respiratory issues, allergies, and asthma exacerbations (Shelton et al., 2021). To address mold problems, it is essential to improve ventilation, especially in moisture-prone areas, and promptly repair any leaks or water intrusion sources.
Asbestos, once widely used in insulation and building materials, poses a risk when its fibers become airborne due to deterioration or disturbance. In older parts of my home, I identified aged insulation that could contain asbestos. Inhalation of asbestos fibers is linked to serious health problems such as asbestosis, lung cancer, and mesothelioma (Hammad et al., 2020). Since disturbing asbestos materials can release fibers, professional removal or encapsulation by certified contractors is advisable if the material deteriorates.
Carbon monoxide is a colorless, odorless gas produced by incomplete combustion of fuel sources such as gas furnaces, stoves, or heaters. During the walk-through, I checked the functioning of fuel-powered appliances and ensured proper ventilation. CO poisoning can cause headaches, dizziness, cardiovascular issues, and in severe cases, death (WHO, 2021). Installing CO detectors on each floor and maintaining appliances regularly can prevent harmful exposure.
Airborne bacterial contaminants can originate from indoor sources like pets, human activity, or inadequate ventilation. I noticed pet dander and bacteria levels could be elevated in areas with limited airflow. Exposure to airborne bacteria can lead to respiratory infections or allergic reactions, especially in vulnerable populations (Chen et al., 2019). Improving ventilation and maintaining cleanliness are practical steps to reduce bacterial load.
In conclusion, my walk-through assessment identified several potential indoor air quality issues. To mitigate radon, installing a venting system is essential; addressing mold through moisture control and ventilation improvements can significantly reduce allergen exposure; professional asbestos removal ensures safety; installing CO detectors and maintaining appliances ensure safety from gas buildup; and enhancing ventilation reduces bacterial contaminants. Overall, continuous monitoring and maintenance of indoor environments are crucial for ensuring healthy living conditions.
