Volatile organic compounds, or VOCs, are emitted by a wide array of products that we use every day, including paints, cleaning supplies, pesticides, building materials, and office equipment. VOCs are organic compounds that have a high vapour pressure at room temperature and are emitted as gases from certain solids or liquids. They are a common pollutant at chemical spill sites and can contaminate soil and leach into groundwater. VOCs can also react with nitrogen oxides to produce ozone pollution, which is a widespread outdoor air pollutant. Exposure to VOCs can cause a variety of adverse health effects, including eye, nose, and throat irritation, headaches, nausea, dizziness, and difficulty breathing.

Volatile organic compounds (VOCs) are emitted by thousands of products, including paints, cleaning supplies, and pesticides
Volatile organic compounds (VOCs) are organic compounds that have a high vapour pressure at room temperature. They are emitted as gases from certain solids or liquids. VOCs are emitted by thousands of products, including paints, cleaning supplies, and pesticides. They are also released by building materials, office equipment, glues, adhesives, and more. These products can release organic compounds while in use and, to a lesser extent, when stored.
Paints, varnishes, and wax contain organic solvents, which are a type of VOC. Many cleaning, disinfecting, cosmetic, degreasing, and hobby products also contain these solvents. Fuels are made up of organic chemicals, and petroleum fuels often contain VOCs. VOCs are also emitted by dry cleaning agents, auto-body shops, and painting and coating facilities.
The health effects of VOC exposure vary, but many VOCs are known to be harmful to humans and the environment. Some common symptoms of VOC exposure include eye, nose, and throat irritation, headaches, nausea, dizziness, and difficulty breathing. Some VOCs are suspected or known to cause cancer in humans.
To reduce exposure to VOCs, it is recommended to use products that are low in VOCs or to reduce the use of products that contain them. Proper ventilation is also important, as increasing the amount of fresh air in a space can help reduce VOC concentrations.
Some VOCs are regulated by law, especially indoors, where concentrations are the highest. The Occupational Safety and Health Administration (OSHA) in the US regulates VOC exposure in the workplace. Target exposure limits for human health have been established in England, Wales, Scotland, and Northern Ireland.

VOCs are organic compounds with a high vapour pressure at room temperature, which vaporises and releases into the air
Volatile organic compounds, or VOCs, are organic compounds with a high vapour pressure at room temperature. They are emitted by thousands of everyday products, including paints, lacquers, cleaning supplies, pesticides, building materials, and furnishings. VOCs are also released by dry cleaners, auto-body shops, painting and coating facilities, and gas engines.
VOCs vaporise and are released into the air during the use of products containing them, a process known as off-gassing. Concentrations of VOCs are consistently higher indoors, up to ten times higher than outdoors. This is due to the widespread use of organic chemicals in household products such as paints, varnishes, wax, cleaning products, cosmetics, and fuels.
The health effects of VOC exposure depend on factors such as the level of exposure and length of time exposed. Immediate symptoms experienced after exposure to some organics include eye, nose, and throat irritation, headaches, nausea, dizziness, and difficulty breathing. Some VOCs are suspected or known to cause cancer in humans, and they can also contribute to the formation of ground-level ozone and smog when they react with nitrogen oxides in the air.
To reduce exposure to VOCs, it is recommended to use products that are low in VOCs, improve ventilation, and dispose of leftover or unused products safely. VOCs are regulated by organisations such as the US EPA, state agencies in the US, and the Occupational Safety and Health Administration (OSHA) in the workplace.

Exposure to VOCs can cause eye, nose, and throat irritation, headaches, nausea, dizziness, and difficulty breathing
Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors.
VOCs are emitted by a wide array of products, including paints and lacquers, paint strippers, cleaning supplies, pesticides, building materials and furnishings, office equipment, graphics and craft materials, permanent markers, and photographic solutions. Organic chemicals are widely used as ingredients in household products. Paints, varnishes, and wax all contain organic solvents, as do many cleaning, disinfecting, cosmetic, degreasing, and hobby products. Fuels are made up of organic chemicals. All of these products can release organic compounds while they are being used and, to some degree, when they are stored.
To reduce exposure to VOCs, increase ventilation when using products that emit them, meet or exceed label precautions, and do not store opened containers of unused paints and similar materials. Formaldehyde, one of the best-known VOCs, is one of the few indoor air pollutants that can be readily measured. If possible, identify and remove the source of VOCs. If removal is not possible, reduce exposure by using a sealant on all exposed surfaces of paneling and other furnishings.

VOCs are monitored as part of the air toxics network in Minnesota due to their role in forming ground-level ozone
Volatile organic compounds, or VOCs, are emitted from thousands of everyday products, including paints, varnishes, cleaning supplies, pesticides, building materials, and even office equipment like printers and copiers. These compounds have a high vapour pressure and low water solubility, and they can have adverse health effects. Some common VOCs include trichloroethylene, methyl tert-butyl ether (MTBE), and chloroform.
In Minnesota, VOCs are a particular concern due to their contribution to ground-level ozone formation. Ground-level ozone is a harmful pollutant that can cause serious health issues and is the nation's most widespread outdoor air pollutant. VOCs react with nitrogen oxides in the air to create ground-level ozone, and as such, VOCs are monitored as part of Minnesota's air toxics network.
The Minnesota Pollution Control Agency (MPCA) is responsible for studying, monitoring, and regulating air pollutants in the state. They collect data on emissions of air toxics from major sources every three years and report their findings in the Minnesota Air Toxics Emissions Inventory. This data is used to monitor and estimate the concentrations of air toxics across Minnesota.
As VOCs are a significant contributor to ground-level ozone, they are a key focus of these monitoring efforts. The MPCA tracks VOC emissions from various sources, including paint, solvents, adhesives, gasoline, cleaning products, and fuel combustion. This monitoring is essential to help reduce ozone concentrations in the air and protect public health.
Additionally, VOCs are a common contaminant in Minnesota when chemical spills or mishandling has contaminated soils. They can leach into groundwater and migrate into drinking water supplies, leading to toxic vapours that can enter buildings and degrade indoor air quality. This process, known as vapour intrusion, further underscores the importance of monitoring VOCs as part of Minnesota's air toxics network.

Some VOCs are known or suspected to be carcinogenic, and can cause damage to the liver, kidneys, and central nervous system
Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. They include a variety of chemicals, some of which have short- and long-term adverse health effects. VOCs are emitted by a wide array of products, including paints, lacquers, paint strippers, cleaning supplies, pesticides, building materials, office equipment, and cosmetics. These products can release organic compounds while being used and, to some degree, when stored.
Some VOCs are known or suspected to be carcinogenic. For example, vinyl chloride exposure has been associated with an excess of liver angiosarcoma. Benzene, carbon tetrachloride, 1,2-dichloroethane, trichloroethylene, chloroform, and other trihalomethanes are also known or suspected carcinogens. VOCs can also cause damage to the liver, kidneys, and central nervous system. Key signs or symptoms associated with VOC exposure include eye and nose irritation, headaches, nausea, dizziness, and fatigue.
The health effects of VOC exposure depend on factors such as the level of exposure and length of time exposed. Concentrations of VOCs are often significantly higher indoors than outdoors, with levels up to 10 times higher inside homes. To reduce exposure, it is recommended to increase ventilation when using products that emit VOCs, follow label precautions, and dispose of leftover products safely.
Additionally, VOCs in air pollution can react with nitrogen oxides to produce ozone pollution, which is a widespread outdoor air pollutant. They can also contaminate groundwater, generating toxic vapors that can enter buildings and degrade indoor air quality.
While VOCs are mostly associated with human-made chemicals, some VOCs, such as isoprene, can be produced through the metabolism of cancer cells or the body's immune system. These VOCs are considered novel cancer biomarkers for diagnostic purposes, aiding in the early detection of several types of cancers.
