Volatile organic compound

(VOC)
Any organic compound that evaporates at room temperature and is hazardous to human health, causing poor indoor air quality. Many VOCs found in homes, such as paint strippers and wood preservatives, contribute to sick building syndrome because of their high vapor pressure. VOCs are often used in paint, carpet backing, plastics, and cosmetics. The U.S. Environmental Protection Agency (EPA) has found concentrations of VOCs in indoor air to be, on average, two to five times greater than that in outdoor air. During certain activities, indoor levels of VOCs may reach 1,000 times that of the outside air.

VOC (volatile organic compounds) emissions from pellets produced from pine and spruce were evaluated at the early stages of the product lifecycle--from wood shredding through transport and storage of the freshly produced pellets.
This rulemaking is significant since the district is considering drastic changes, including lowering the VOC limits for Flats, Nonflats, and Primers, Sealers, Undercoaters; restructuring the Rule 314 fee structure on the sale of coatings in the district; eliminating the small container exemption for certain major coatings categories; proposing a spray equipment training program and "best practices guidelines" for contractors; and incorporating a new VOC test method in Rule 1113.
Powder coatings are inherently low-VOC because they are solvent-free and, while most e-coats contain some small amount of co-solvent, modern use of this technology produces few, if any, VOC emissions," said PPG's spokesperson.
When implemented at a facility that chooses to recover and re-route emitted VOCs or reuse the vaporized nitrogen, cryocondensation can be a low-cost solution that increases production safety.

Following a few simple guidelines can help to minimize exposure to VOCs in paint and elsewhere.
According to the EPA, about a dozen common VOCs are consistently found at two to five times higher levels inside homes than out, even in rural settings.
Correlations between the internal diffusion and equilibrium partition coefficients of volatile organic compound (VOCs) in building materials and the VOC properties.
Their understanding of the need for a better way to treat VOC emissions demonstrates their commitment to energy and environmental issues," said Karl Mundorff, President/CEO of Bio-Reaction Industries.
A user requiring true "VOC-free" material should inquire as to the additive used on a candidate water-based flux, as organic co-solvents may themselves be VOCs.
With vegetable oil content ranging from 38 to 51 percent, Earth series inks produce only 2 percent VOCs (volatile organic compounds--EPA Method 24), which makes this ink technology 80 percent lower in average VOCs than other standard sheetfed process inks now available.
