Mold Assessment Technician Practice Exam

What might cause symptoms of illness if no mold growth is found in a building?

1. Excessive light

2. Volatile organic compounds (VOCs)

3. High humidity

4. Low temperature

The correct answer is: Volatile organic compounds (VOCs)

The presence of volatile organic compounds (VOCs) in a building can contribute to illness symptoms even in the absence of mold growth. VOCs are organic chemicals that can easily evaporate into the air and are commonly found in many household items, including paints, cleaning supplies, and furniture materials. When inhaled, they can cause a range of health issues, including respiratory problems, headaches, dizziness, and other symptoms. This makes VOCs a significant factor in indoor air quality concerns. Other choices may lead to discomfort or other issues, but they do not directly cause the same spectrum of health symptoms as VOCs. For instance, excessive light can cause eye strain or fatigue, high humidity may lead to discomfort or exacerbate respiratory conditions, and low temperatures can contribute to feelings of being cold or uncomfortable. However, the specific and acute health effects associated with VOCs make this the most relevant option regarding symptoms of illness without mold present.
