Volatile Organic Compounds (VOCs) are chemicals that do which of the following?

Volatile Organic Compounds are chemicals that can evaporate at normal indoor temperatures and pressures. This is why they are important in LEED Indoor Environmental Quality. VOCs can off-gas from products such as paints, coatings, adhesives, sealants, flooring, composite wood, furniture, and other interior finishes. High VOC concentrations can create odors, irritation, headaches, discomfort, and other health concerns for occupants. Option B is incorrect because VOCs are specifically volatile under ordinary indoor conditions. Option C is incorrect because VOCs can come from many manufactured products and materials, not only soil. Option D is incorrect because VOCs can negatively affect indoor air quality and occupant well-being. LEED addresses this issue through low-emitting material requirements and indoor air quality strategies.
