CAS VOC

Volatile Organic Compounds

CAPVOC

Volatile organic compounds (VOCs) are a large group of chemicals that easily become gases. They come from many everyday products and can build up indoors, affecting air quality and health [1][2].

Where It Comes From

Paints/solvents, cleaners and air fresheners, adhesives, new furniture and building materials, dry-cleaned clothes, fuels, vehicle exhaust, industry, and tobacco smoke [1][2].

How You Are Exposed

Breathing indoor air during and after product use; inside cars or near traffic; at work with solvents/paints; sometimes via contaminated water [1][2].

Why It Matters

Can cause eye/throat irritation, headaches, dizziness, and worsen asthma; long-term, some VOCs can harm liver, kidneys, or nerves, and some (e.g., benzene, formaldehyde) cause cancer [1][2][3][4]. Indoor VOC levels are often 2–5 times higher than outdoors [1].

Who Is at Risk

Children, older adults, people with asthma/COPD, pregnant people, and workers in painting, printing, dry cleaning, or auto repair [1][2].

How to Lower Your Exposure

Choose low-/no-VOC products; ventilate well; follow labels; store/dispose chemicals safely; let new items off-gas; don’t smoke or idle engines indoors; use exhaust fans and protective gear at work [1][2].
