Key signs or symptoms associated with exposure to VOCs include:
- conjunctival irritation.
- nose and throat discomfort.
- headache.
- allergic skin reaction.
- dyspnea.

- nausea.
- emesis.
Correspondingly, What causes VOCs in the home? 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.
Do humans emit VOCs? Human beings emit many volatile organic compounds (VOCs) of both endogenous (internally produced) and exogenous (external source) origin.
Furthermore, How do VOCs harm the environment?
How do VOCs cause smog? VOCs play a significant role in the formation of ozone and fine particulates in the atmosphere. Under sunlight, VOCs react with nitrogen oxides emitted mainly from vehicles, power plants and industrial activities to form ozone, which in turn helps the formation of fine particulates.
What is the most common VOC?
Methylene Chloride
Also known as dichloromethane, this is one of the most common VOCs. It’s present in paint removers, aerosol solvents and other flame retardant chemicals.
What is the largest source of VOCs? Petroleum and natural gas extraction, petrochemical activities and the burning of fossil fuels in industries, homes and mobile sources, including automobiles, trucks, buses and motorcycles, ships and airplanes are the major contributors of VOC, followed by chemical and industrial processes (manufacturing of paints, …
What is an example of a VOC? Common examples of VOCs that may be present in our daily lives are: benzene, ethylene glycol, formaldehyde, methylene chloride, tetrachloroethylene, toluene, xylene, and 1,3-butadiene.
What is the largest source of VOCs in the US? Humans Identified as the Largest Source of Volatile Organic Chemicals in Indoor Air. US researchers found that people and their possessions directly emitted 57% of the volatile organic compounds (VOCs) they measured in the air of a university lecture theatre[1].
What is the smell of VOC?
Many smells that come from products for the home contain volatile organic compounds, or VOCs. The scent can be natural, as from a pine tree or a fresh orange. It can also be man-made, like an artificial pine-scented cleanser or the smell of drying paint. Some VOCs may not produce an odor at all.
How do you remove VOCs from air? To effectively remove them from your home and improve your IAQ, you do need to use activated carbon in addition to or instead of other air filtration methods. Activated carbon will not remove all other airborne pollutants, but it’s the most consistently effective method for removing VOCs.
How do VOCs affect plants?
VOCs may cause detrimental effects on leaves, flowering, seed production, protein content, plant metabolism, and total dry weight. … … It is known that environmental pollution causes a decrease in the seed production of different plant species [1][2] [3] [4][5].
How do VOCs affect fish? Some of the most adverse effects take place in aquatic environments. At pH levels above 5, most fish eggs are unable to hatch and at lower levels, adult fish start to die with some lakes so acidic they don’t have any fish.
Which products contain VOCs?
VOCs come from many commonly used products and indoor furnishings, such as:
- Gasoline, fuels, and solvents.
- Paints, stains, strippers, and finishes.
- Pesticides.
- Personal care products.
- Aerosol sprays.
- Cleaners and room deodorizers.
- New cabinets, furniture, and beds.
- New carpets, rugs, and wood floors.
Is alcohol a VOC?
Introduction. The major volatile organic compounds (VOCs) of alcoholic beverages are aldehydes such as acetaldehyde, low-molecular-weight alcohols such as methanol, and higher alcohols (Geroyiannaki et al.
How do you identify a volatile organic compound? The two most commonly used methods for VOC statistical analysis are Flame Ionisation Detection and Photo Ionisation Detection. Both methods measure the number of chemicals in the air on the assumption that most organic vapors produce positively charged carbon ions when they combust(1).
Do people exhale VOC? The medical community has long recognized that humans exhale volatile organic compounds (VOCs). Several studies have quantified emissions of VOCs from human breath, with values ranging widely due to variation between and within individuals.
Why do VOCs increase at night?
Exposure to high levels of VOCs can cause eye, nose and throat irritation, headaches, and for some compounds, even cancer. During sleep, people likely inhale more VOCs because of poor bedroom ventilation and the close proximity of their nose and mouth to mattresses and bedding that emit the compounds.
Are VOCs air pollutants? VOCs mean volatile organic compounds and are found in a wide variety of products such as solvent-based paints, printing inks, many consumer products, organic solvents and petroleum products. Motor vehicles and vessels also emit VOCs that eventually cause air pollution and smog.
Why do VOCs go up at night?
Exposure to high levels of VOCs can cause eye, nose and throat irritation, headaches, and for some compounds, even cancer. During sleep, people likely inhale more VOCs because of poor bedroom ventilation and the close proximity of their nose and mouth to mattresses and bedding that emit the compounds.
How do you know if something is a VOC? 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.
