Indoor Air Quality and Volatile Organic Compounds - 2

Summary People spend 90% of their time indoors where concentrations of gaseous pollutants are significantly higher than outdoors. The widespread use of new products and building materials, as well as improved insulation for energy efficiency, has resulted in increased concentrations of volatile organic compounds (VOCs). These VOCs originate mainly from paints and solvents, carpets and furniture, and cleaning agents, and are also emitted by humans. Elevated VOC levels can have a negative impact on well being, comfort, and cognitive abilities. Exposure to high levels of VOCs can be avoided or...

Potential Health Effects of High VOC Concentrations SENSORY IRRITATION COGNITIVE ABILITIES SICK BUILDING SYNDROME A number of systematic human exposure studies have shown various adverse health effects caused by exposure to elevated VOC levels3. Among the effects reported by participants are dryness and irritation of the eye, the nose and the throat, headaches, and dizziness. Poor indoor air quality can lead to decreased cognitive function resulting in significant impacts on productivity, learning, and safety. Recent studies have demonstrated clear negative effects of elevated VOC levels on...
