Like nitrogen oxides, SO 2 is a major contributor to smog and acid rain. SO 2 is closely related to sulfuric acid, a strong acid. It can harm vegetation and metals and can cause lung problems, including breathing problems and permanent damage to lungs. All organic compounds contain carbon, and organic chemicals are the basic chemicals found in all living things and in all products derived from living things. Many organic compounds we use do not occur in nature, but were synthesized by chemists in laboratories.
Volatile chemicals produce vapors easily.
At room temperature vapors readily escape from volatile liquid chemicals. VOCs are released from burning fuel, such as gasoline, wood, coal, natural gas and from solvents, paints, glues, and other products used at home or work. Vehicle emissions are an important source of VOCs. There are many ways to reduce air pollution. NO x , ozone, VOCs, HAPs, CFCs, and particulate matter, each driver who makes personal changes in driving habits contributes to the reduction of air pollution.
