Compostos carbonílicos atmosféricos: fontes, reatividade, níveis de concentração e efeitos toxicológicos

Abstract

ATMOSPHERIC CARBONYL COMPOUNDS: SOURCES, REACTIVITY, CONCENTRATION LEVELS AND TOXICOLOGIC EFFECTS. In the last three decades carbonyl compounds, aldehydes and ketones, have received a great deal of attention due to their strong influence on photochemical smog formation and their recognized adverse human health effects. Carbonyl compounds are directly emitted into the atmosphere by combustion sources and also produced from photochemical oxidation of hydrocarbons and other organic compounds. In this paper it is presented a general overview about the carbonyl compounds sources, reactivity, concentration levels and toxicological effects.
