Volatile Organic Compounds (VOCs) as Environmental Pollutants

Dec 13, 2021 · Volatile organic compounds (VOCs) are organic chemical compounds found in various products that easily vaporise and reach in the environment under normal conditions. VOCs have increased volatility, mobility and they are resistant to degradation, being able to be transported to long distances in the environment [ 1 ].

Halogenated Volatile Organic Compounds in Water Samples and

Among thousands of organic compounds present in environmental matrices, halocarbons, i.e., organic chemical molecules containing at least a chemical covalent bond between a carbon atom and one (or more) halogen atoms [11,12], are very toxic (and some of them also carcinogenic), the most common are fluorine, chlorine, bromine and iodine [13,14

Volatile Organic Compounds (VOC) Testing - Testing Lab / Alfa

Note: this service is for Research Use Only and Not intended for clinical use. Volatile organic compounds (VOC) are organic chemicals that have a high vapor pressure at ordinary room temperature, which means these compounds can evaporate or sublimate from the liquid or solid form and enter the surrounding air.

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

Feb 27, 2019 · 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 supply wells.
