Outdoor air pollution includes harmful chemicals and particulates mostly from vehicles, industries, and power plants. Indoor air pollution comes from carbon monoxide, VOCs, and biological contaminants like mold, mites, and pet dander, with higher potential concentrations due to lack of ventilation.

Explanation:

Air pollution is categorized into outdoor air pollution and indoor air pollution. Outdoor pollutants typically include fine particles from coal burning, sulfur dioxide, nitrogen oxides, carbon monoxide, ground-level ozone, and tobacco smoke. Significant sources are vehicles, industrial facilities, and power plants. On the other hand, indoor air pollution involves pollutants that may be more concentrated indoors due to less ventilation and can include carbon monoxide, radon, volatile organic compounds (VOCs), allergens such as mites, smoke, mold, bacteria, and pet dander. Household products, building materials, environmental tobacco smoke, and central heating and cooling systems also contribute to indoor air pollution.
