MEDICIÓN Y ANÁLISIS DE LOS COMPUESTOS ORGÁNICOS VOLÁTILES EN LA ATMÓSFERA: ÚLTIMAS TÉCNICAS, APLICABILIDAD Y RESULTADOS A NIVEL EUROPEO

Abstract

Volatile Organic compounds (VOC) are considered as one of the most pollutants presents in the atmosphere. They deserve an especial attention because of with the nitrogen oxides they are keys compounds to understand the troposphere ozone formation. VOC can also contribute to secondary organic aerosol (SOA) formation; SOA can lead to increase finer particle matter and contribute to climate change.

Health effect are also important; some VOC have little or unknown direct health effect, while other VOC, such as benzene and 1,3-butadiene, are carcinogens.   For   that   reason,   during   the   last decades, research has focused on VOC measurement on urban, rural and industrial area.
Existing measurement methods are generally compose    by        a          sampling           unit, preconcentration/desorption/injection/ unit of VOC contained in sampling unit, chromatographic colon and a flame ionization detector (FID) and/or spectrometer mass.
