What are examples of semi-volatile organic compounds?
Examples of semivolatiles compounds include hydrocarbons, aldehydes, ethers, esters, phenols, organic acids, ketones, amines, amides, nitroaromatics, PCBs (also known as Aroclors), PAHs, phthalate esters, nitrosamines, haloethers and trihalomethanes.
Are PAHs and SVOCs the same?
Polycyclic Aromatic Hydrocarbons (PAHs) are a group of semi-volatile organic compounds (SVOCs) that are present in crude oil that has spent time in the ocean and eventually reaches shore and can be formed when oil is burned.
What are semi-volatile compounds?
Semi-volatile compounds are a broad term used to describe a number of classes of compounds that have relatively lower volatility. Semi-volatile organic compounds can also remain in water supplies for long periods of time, meaning they can accumulate in eventually harmful quantities.
Is Naphthalene a Semivolatile?
Semivolatile organic compounds (SVOCs) are a subgroup of VOCs that tend to have a higher molecular weight and higher boiling point temperature….The following analytes are commonly reported:
| N-nitrosodimethylamine | 2,4-dinitrotoluene |
|---|---|
| naphthalene* | benzidine |
| benzoic acid | pyrene* |
What are SVOCs used for?
Used as a general solvent for inks, waxes, shellacs, paints and lacquers, this SVOC is one of the most common. It is also used in the construction of nanowires, and it has been approved (when diluted to a 5 percent solution) as a treatment for head lice.
Is alcohol a VOC?
VOC is most often stated as a percentage, so the percentage of the full mixture that is not VOC exempt. For example, isopropyl alcohol (IPA) is not exempt by EPA (and most if not all other) standards, so 99% pure IPA has a VOC of 99%. 70% pure IPA, with 30% purified water, is 70% VOC, because water is exempt.
Is Naphthalene a VOC or Svoc?
volatile organic compound
Naphthalene is both a volatile organic compound (VOC) and a polycyclic aromatic hydrocarbon (PAH) that is ubiquitous in indoor and outdoor air.
What is non volatile organic compounds?
A nonvolatile compound is defined here as a compound that evaporates less than 5% by weight in 6 months under ambient evaporation testing conditions. Alkyl alkanolamine, methyl palmitate, soy oil, and glycerol all fall under this category. Several compounds had minor weight gain during the study.
