Volatile organic compound Volatile organic compounds (VOCs) are organic chemicals that have a high vapor pressure at ordinary room temperature.ost scents or odours are of VOCs. VOCs play an important role in communication between plants, and messages from plants to animals. Some VOCs are dangerous to human health or cause harm to the environment.

Low & Zero VOC Paint Significant VOC sources are chemical plants, gasoline pumps, autobody shops, print shops, consumer products and paint and coatings. Apply a coat of cleaner air Even years after application, paints and finishes can release low level toxic emissions into the air. The source for these toxins is a variety of volatile organic compounds, or VOCs. Our interior paints are only low and zero VOC, and promote healthy indoor air quality.

Non-Toxic Paints Zero VOC - Any paint with VOC's in the range of 5 grams/litre or less can be called Zero VOC, according to the EPA Reference Test Method 24. Some manufacturers may claim Zero-VOC's, but these paints may still use colorants, biocides and fungicides with some VOC's.

Volatile Organic Compound (VOC) Control Regulations State VOC regulations have to at least meet a level of stringency we call RACT, or Reasonably Available Control Technology. RACT is defined as the lowest level of emissions that can be achieved taking into account technical and economic considerations.

- There are a variety of chemical contaminants found in a variety of sources. Volatile organic compounds (VOCs) are common chemical contaminants found in office and home environments and are a source of odors. VOCs are organic (containing carbon) chemicals that can easily evaporate into the air.Many products found in the office environment may have the potential to release VOCs.dors are organic or inorganic compounds and can be both pleasant and unpleasant. Some odors can be health hazards and some are not. While most chemical contaminants originate from within the building, chemicals can be drawn into a building from the outdoors as well.

What is the difference between VOCs and SVOCs? As the name implies a VOC is a Volitile organic compound. An SVOC is a Semi volitile organic compound.Therefore an SVOC is not as volitile as a VOC. This is an example from the EPA website.aking the world better, one answer at a time. As the name implies a VOC is a Volitile organic compound. An SVOC is a Semi volitile organic compound. Therefore an SVOC is not as volitile as a VOC.

Volatile Organic Compounds' Impact on Indoor Air Quality Common VOCs: Methylene Chloride. Products which contain methylene chloride include paint strippers, adhesive removers and aerosol spray paints. According to the EPA, methylene chloride is converted to carbon monoxide in the body and can cause symptoms associated with exposure to carbon monoxide, which can be fatal.

Volatile organic compound Volatile organic compound. Volatile organic compounds (VOCs) are organic chemicals that have a high vapor pressure at ordinary room temperature. Their high vapor pressure results from a low boiling point, which causes large numbers of molecules to evaporate or sublimate from the liquid or solid form of the compound and enter the surrounding air, a trait known as volatility.

Measuing Dissolved and Particulate Organic Carbon (DOC and POC) Dissolved organic carbon (DOC) is defined as the organic matter that is able to pass through a filter (filters generally range in size between 0.7 and 0.22 um).Conversely, particulate organic carbon (POC) is that carbon that is too large and is filtered out of a sample.If you have ever seen a body of water that appears straw, tea, or brownish in color, it likely has a high organic carbon load.onversely, particulate organic carbon (POC) is that carbon that is too large and is filtered out of a sample.

- Volatile organic compounds, or VOCs are organic chemical compounds whose composition makes it possible for them to evaporate under normal indoor atmospheric conditions of temperature and pressure. This is the general definition of VOCs that is used in the scientific literature, and is consistent with the definition used for indoor air quality.
