2020. 8. 12. · Sources of VOC and NOx emissions include: large industry such as chemical manufacturers, and combustion sources such as power plants burning fossil fuels; small

Volatile organic compounds, or VOCs, are a group of hydrocarbons characterized by high vapor pressure. At normal indoor temperatures, VOCs evaporate, entering the air as potentially harmful air pollutants. VOCs are usually associated with chemical odors, but it is worth noting that some VOCs don't carry a smell, and some odors don't have

2022. 6. 25. · VOCs are a big source of both indoor and outdoor air pollution. However, most of the time when people talk about VOCs, they’re talking about this group of chemicals as it relates to household products and indoor air quality. It’s important to

Common sources of these organic compounds in the home are: Paint Furniture polish and other wood finishing products Cleaners, including soaps and laundry detergents Solvents and thinners, e.g. nail polish remover with acetone or paint thinner. Aerosols, such as air fresheners and other cleaners

Other sources of VOCs include the burning of fuels such as gas, wood and kerosene and tobacco products. VOCs can also come from personal care products such as perfume and hair spray, cleaning agents, dry cleaning fluid, paints, lacquers, varnishes, hobby supplies and from copying and printing machines.

Indoor volatile organic compounds, or VOCs, are carbon-containing organic chemicals present in indoor air. They come from a large number of indoor sources including building materials, furnishings, consumer products, tobacco smoking, people and their activities, and indoor chemical reactions. Pollutants from attached buildings such as garages

What are the sources of VOCs? VOCs arise from a broad range of different sources. Their presence in atmospheric air can be accounted for by 

In ambient air, we found that fossil fuel VOCs [from mobile sources and from local oil and natural gas production and distribution ( 36 )] can only account for 61% of the mass of freshly emitted VOCs measured, and 59% of their variability ( Fig. 3A ).

Industrial processing and solvent use are two most important industrial sources of volatile organic compounds (VOCs) in China, and the source profile study has attracted increasing attention recently. Studies of VOCs source profiles from industrial processing and solvent use since the year of 2000 were summarized in this study, focusing on the

Variations and sources of volatile organic compounds (VOCs). 1 in urban region: insights from measurements on a tall tower.

Important VOC sources include cleaning products, tobacco smoke, cooking, heating appliances, VOC outgassing (from furniture, floor and wall
