what are the sources of vocs?

One of the primary sources of VOCs is pesticides primarily used in our farms to control pests. After the pesticide gets exposed to the atmosphere, 

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.

Many VOCs are relatively benign, and humans have evolved to coexist with them. Vegetation is a major source of isoprene, a terpenoid VOC that gets emitted naturally during the routine life cycles of tree species like eucalyptus and oak. Each year, 600 million metric tons of isoprene enter the air.

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.

Common sources include petroleum fuels, hydraulic fluids, paint thinners and dry-cleaning chemicals, according to the EPA (opens in new tab).

2021. 5. 26. · VOCs can originate from both natural sources and anthropogenic sources. We won’t discuss natural sources of VOCs here, and we will instead focus on indoor sources common to office and workplace environments. VOCs are common ingredients in many consumer products and building materials, and there are numerous sources of VOCs in an office

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 ).

Volatile organic compounds (VOCs) are key precursors of O 3 and secondary organic aerosols (SOAs) - a major component of fine particulate matter (PM 2.5).VOCs significantly contribute to the formation of photochemical smog, atmospheric oxidative capacity, visibility degradation, and global climate (Jenkin and Clemitshaw, 2000; Seinfeld and Pandis, 2006), and some VOCs are also known to be

2022. 9. 9. · VOC stands for Volatile Organic Compounds, and you may have them in your home without realizing it. Find out what they are and how to reduce VOCs. When it comes to the home, paint is a common source of VOCs. These chemicals are pretty necessary for paint as they allow the paint to stick to the walls.

Carbon filters and VOCs. Air purifiers with carbon filters are designed to remove gaseous pollutants from indoor air. These filters use a process called adsorption to capture VOCs and other harmful gases. As air passes through the filter, gaseous pollutants stick to the outside of the carbon particles in the adsorption area.
