What is the difference between voc and svoc

These long term health effects include cancer, lung disease, damage to your immune system, and heart disease. However, you can avoid these long-term health effects by using preventative methods for reducing harmful VOCs.

Sometimes VOCs are classified by how easily they are emitted into the air. In other words, the more volatile they are having lower boiling points , the easier they are emitted into the air. Compounds that are extremely volatile are hard to measure because they are almost entirely in the air as a gas, or they are found as tiny dust particles on top of surfaces. The majority of VOCs will be found in solids or liquids that have evaporated into gases.

These types of volatile compounds are broken into different classifications:. VOCs are released into the air when harmful chemicals vaporize. The boiling point of a particular compound can be used to gauge how easily it vaporizes, and therefore how volatile it is. The lower the boiling point, the higher the volatility.

The EPA monitors the amount of VOCs released into the air by manufacturing plants and sets restrictions on their annual emissions. By understanding which type of VOC is being released throughout the production cycle, manufacturers can choose the right emission control system for their particular plant.

While the compounds in each category are still considered harmful, their varying boiling points affect how easily they can be absorbed into the air. However, VOC emission limits do not only apply to outdoor vapors. The quality of indoor environments must also be carefully monitored by manufacturers. It is also used as a fragrance in perfumes and in flavoring, and is an ingredient in ointments and cosmetics.

Also used in inks, as a photographic developer, and in dyeing nylon filament, textiles and sheet plastics. A significant source of SVOCs are flame retardant chemicals such as those found in fire extinguishers.

VOCs are ubiquitous in indoor air, the questions are: what concentration levels are in the air you breathe? Using sensors to sample indoor air quality and measure VOC concentrations is the only way to know for sure. Butane Used in an almost identical fashion to propane, butane is contained in items including camping stoves, lighters, torches, fridges and freezers. Methyl Chloride Also known as Chloromethane, this is colorless, flammable, toxic gas that is widely used as a refrigerant but has many other industrial applications.

Formaldehyde This VOC is a known carcinogen. Vinyl Chloride Used to make PVC plastics, piping, floor coverings and consumer goods, Vinyl Chloride is also known as chloroethene, chloroethylene and ethylene monochloride. Toluene An important chemical used as a gasoline additive and to make nylon, plastics, solvents, dyes, inks and paints.

Isopropyl alcohol Used in making cosmetics, skin and hair preparations, pharmaceuticals, perfumes, lacquer formulations, dye solutions, antifreezes, and soaps. Hexanal Hexaldehyde is used as a flavoring in food production and as a fragrance in perfumes. Carbon Disulfide Also called Carbon Bisulfide, this highly volatile compound is used in the manufacture of viscose rayon and cellophane.

Pesticides Organochlorine pesticides, one more widely known as DDT was used extensively from the s to the s in agriculture and mosquito control. Benzyl Alcohol Benzyl alcohol is used as a solvent, a preservative, and to make other chemicals. Fire retardants A significant source of SVOCs are flame retardant chemicals such as those found in fire extinguishers. Events News. Contact Us. Tests we perform Ready to request a quote? Contact us.
