Volatile organic compounds (VOCs) are organic chemicals that have a high vapor pressure at ordinary room temperature.Their high vapor pressure results from a low boiling point, which causes large numbers of molecules to evaporate or sublimate from the liquid or solid form of the compound and enter the surrounding air, a trait known as volatility.For example, formaldehyde, which evaporates from ...

What's Wrong with MethaneWhat Causes These LeaksInventory Tallies vs. Aircraft SurveillanceHelpful Gadgets and Sound PolicyOne way to quantify the magnitude of the methane leakage is to divide the amount of methane emitted each year by the total amount of methane pumped out of the ground each year from natural gas and oil wells. The EPA currently estimates this methane leak rate to be 1.4 percent. That is, for every cubic foot of natural gas drawn from underground reservoirs, 1.4 percent of it is lost into the atmosphere. This study synthesized the resul…See more on pbs.orgGas Leak Detector | Gas Detector | Screwfix.com gas detectors detect a variety of combustible gases.
