Publications. Volatile organic compounds (VOCs) are chemicals that both vaporize into air and dissolve in water. VOCs are pervasive in daily life, because they're used in industry, agriculture, transportation, and day-to-day activities around the home. Once released into groundwater, many VOCs are persistent and can migrate to drinking-water

emissions varies with the manner in which the resin is mixed, applied, handled, and cured among the different fabrication processes. For example, the spray lay-up operation has highest potential for VOC emissions because the atomization of resin into spray creates an extremely large surface area from which volatile monomer can evaporate.

Thus, VOC emissions from biogenic and forest wildfire sources are larger than the VOC emissions from all anthropogenic sources combined. In nine of the EPA Regions, estimated anthropogenic VOC emissions decreased between 1990 and (Exhibit 3). Changes in VOC emissions ranged from a 70 percent reduction (Region 2) to a 68 percent increase

Volatile organic compounds (VOCs), except methane, are called nmVOCs. Such compounds evaporate from crude oil. Storage, loading and unloading of oil offshore, in storage ships (FSOs and FPSOs), in onshore storage tanks and terminals, and on shuttle tankers, contribute significant emissions of nmVOCs.

A VOC is any organic compound having an initial boiling point less than or equal to 250° C measured at a standard atmospheric pressure of 101.3 kPa. 5, 6, 7. VOCs are sometimes categorized by the ease they will be emitted. For example, the World Health Organization (WHO) categorizes indoor organic pollutants as: Very volatile organic compounds (VVOCs)

After all, simply put: It is the content of Volatile Organic Compounds in the product. It does appear simple, but there's more to it. Many products on the market that require VOC content testing have highly volatile compounds as the primary ingredient, and that ingredient under certain regulations can be exempt from the final VOC content results.

Examples of Potential VOC emissionsin a sentence. Potential VOC emissionsare less than 3 pounds per hour and potential HAP emissions are less than 1 ton per year. Potential VOC emissionswere determined based on the following equation from the permittee-supplied information in FEPTIO application 14-06026 as submitted on February 21, : VOC emissions = (6093 lbs of cooked product/hr)/(2000 lbs/ton) x (3.88 lbs of stack VOC/ton of cooked product) x (1 - 20% control efficiency for VOC).
