Occurrence Of Oxygenated Volatile Organic Compounds (Voc) In Antarctica

Polar and non-polar VOC present in six different sites located near Terra Nova Bay in Antarctica were determined by HRGC-MS. 76 different components were positively identified. Among them, particularly important are oxygenated components (free acids, aldehydes, ketones, alcohols, esters, ethers and furanes) as they account for the largest portion of the organic fraction. Biogenic emission seem to be the major source for many of them. This would explain their ubiquitous occurrence in the troposphere.
