- In air pollution: Air toxics
Many are volatile organic compounds (VOCs), organic compounds that readily evaporate. VOCs include pure hydrocarbons, partially oxidized hydrocarbons, and organic compounds containing chlorine, sulfur, or nitrogen. They are widely used as fuels (e.g., propane and gasoline), as paint thinners and solvents, and in

- In air pollution control: Control of gases
…criteria pollutants, as well as volatile organic compounds (VOCs) and other gaseous air toxics, are controlled by means of three basic techniques: absorption, adsorption, and incineration (or combustion). These techniques can be employed singly or in combination. They are effective against the major greenhouse gases as well. In addition, a…

…of volatile organic content (VOC) that can be released into the air. (In oil-based surface coatings, VOC is represented by the solvents.) In addition, alkyd resins tend to have lower exterior durability than many of the newer polymer systems. They retain their use in low-performance industrial coatings and interior…

use in surface coatings
- In surface coating: Solvents and carrier liquids
…low-molecular-weight substances, known collectively as volatile organic compounds (VOC), are released into the atmosphere upon application and curing of the coating. At low elevations they contribute to the generation of ozone, which is a major component of air pollution in urban areas. Therefore, cities such as Los Angeles that have…
