VOCs are organic compounds that are composed primarily of carbon and hydrogen atoms.

Natural gas is not a common source of VOCs, unlike gasoline-powered vehicles, industrial solvents, and trees and plants.

VOCs are known to be carcinogenic, meaning they can cause cancer.

Driving less is not a direct way to reduce VOC emissions from vehicles, unlike using catalytic converters, reformulating gasoline, and using electric vehicles.

Photochemical smog is the term used to describe the process of VOCs reacting with sunlight to form smog.

Carbon monoxide is not a common VOC found in indoor air, unlike formaldehyde, benzene, and trichloroethylene.

VOCs in indoor air can come from a variety of sources, including building materials, cleaning products, and personal care products.

Heart disease is not a common health effect associated with indoor VOC exposure, unlike eye irritation, headaches, and asthma.

Air purification, dehumidification, and ventilation are all methods used to remove VOCs from the air.

Ultraviolet light is not a common air purifier technology used to remove VOCs, unlike activated carbon filters, HEPA filters, and ionizers.

VOC monitoring devices are used to measure VOC concentrations in the air, identify the sources of VOCs, and assess the health risks associated with VOC exposure.

Increasing production rates is not a common method for reducing VOC emissions from industrial sources, unlike using pollution control devices, reformulating products, and substituting less-toxic chemicals.

The Stockholm Convention is the primary international agreement aimed at reducing VOC emissions.

Chlorofluorocarbons are not common VOCs found in the atmosphere, unlike methane, ethane, and propane.

Condensation is the term used to describe the process of VOCs condensing into liquid droplets in the atmosphere.
