Volatile Organic Compounds (VOCs) | U.S. Geological Survey

Feb 27, 2019 · Publications. Volatile organic compounds (VOCs) are chemicals that both vaporize into air and dissolve in water. VOCs are pervasive in daily life, because they’re used in industry, agriculture, transportation, and day-to-day activities around the home. Once released into groundwater, many VOCs are persistent and can migrate to drinking-water

Passive air sampling for semi-volatile organic chemicals

The SR of an unsheltered sampler indoors was either ∼2.5 m 3 per day 161,162 or 1.5 m 3 per day. 256 In order to separate particle-bound and gaseous SVOCs, Wang et al. placed a GFF for sampling of particles slightly above the standard PUF disk, which itself was placed at the top of a stainless-steel bowl . 163 This resembles the set-up by

VOC - Volatile Organic Compounds, VOC Mix | Aijiren

Volatile Organic Compounds. Volatile organic compounds (VOCs) are organic chemical compounds that can evaporate under normal indoor temperature and pressure conditions. These compounds are hard to measure due to their volatility. Regulatory bodies outline analysis of volatile organic compounds or pollutants in matrices such as water and air.
