Quizplus · Accepted Answer

VOCs (volatile organic compounds) are organic chemicals that easily vaporize at room temperature. They are released from many different sources, including incomplete burning of hydrocarbons such as gasoline, natural gas, and wood. Other sources of VOCs include solvents, paints, cleaning agents, and consumer products. Combustion of sulfur-containing fuel (B) can release sulfur dioxide (SO2) and sulfur trioxide (SO3), which are not classified as VOCs. Photochemical oxidation (C) is a chemical reaction that can occur between VOCs and nitrogen oxides (NOx) in the presence of sunlight, leading to the formation of ground-level ozone, a harmful air pollutant. CO (carbon monoxide) in the atmosphere (D) is not a VOC, as it is not an organic compound. Similarly, COS (carbonyl sulfide) in the atmosphere (E) is not a VOC, as it is not a volatile organic compound.
