2022. 8. 23. · Outdoors, VOCs can cause similar health effects, but also can react with nitrogen oxides to produce ozone pollution, the nation's most widespread outdoor air pollutant. Protecting yourself from VOCs Avoid or limit use of products with high VOCs. Use products that are low in VOCs, including some sources like paints and building supplies.

Thus in poorly ventilated buildings indoor emission source strength is considered a more significant influence on VOC concentrations than 

The average concentrations ranged from 0.77 to 265 μg m−3 at the different indoor sites, with the most abundant VOC found to be toluene (119.6 

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 ).

Conduct a walk-through around your entire home, and make a note of anything that could be a source of VOCs. Look for unused chemicals, in particular, such as a paints, solvents, adhesives, varnishes, and caulks. Even when stored, these products can cause VOCs to leak into your home's air.

2021. 5. 7. · VOCs can have deleterious short-term and long-term effects on the health of humans, as well as harm plants, animals, and the natural environment. Sources of VOCs. Volatile organic compounds are present in substances used in everyday life. Both domestic and industrial products are potential sources of VOCs.

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 

Volatile Organic Compounds, or VOCs, are organic chemicals that evaporate into the atmosphere at room temperature. Some VOCs can also dissolve into groundwater. Gasoline and natural gas are a major source of VOCs that impact outdoor air quality. Vehicle exhaust and burning fossil fuels, wood, and garbage all release VOCs into the atmosphere

2022. 5. 16. · VOCs from Vehicle Emissions. Another significant source of VOCs is vehicle emissions. Gasoline and diesel engines emit a variety of VOCs, including benzene, toluene, and xylene. These pollutants can enter your home through open windows or doors, or even through the cracks in your walls and floors. So there you have it!

Volatile organic compounds (VOCs) play important roles in the atmosphere via three main pathways: photochemical ozone formation, 

Sources of Indoor Air Pollution (VOC's) excerpts from An Introduction to Indoor Air Quality by the Environmental Protection Agency (EPA) Organic chemicals are widely used as ingredients in household products. Paints, varnishes, and wax all contain organic solvents, as do many cleaning, disinfecting, cosmetic, degreasing, and hobby products.
