Texto completo del documentoAmbient levels of carbonyl compounds and their possible sources were studied at three places in the metropolitan area of Costa Rica, including a residential, an industrial, and a com mercial downtown area with high vehicular flow, during the periods of April–May and September– December 2009. Fifteen carbonyl compounds were identified in the ambient air, of which ace tone was the most abundant carbonyl, followed by formaldehyde and acetaldehyde. Concentra tions were highest in rainy season at all sites and lower in dry season. These decreases in concen tration are explained by the influences of both photochemical reactions and local meteorological conditions. The strong correlation between C1– C2 and C3...
