1. Estudo das concentrações dos clorofluorcabonetos CFC-11 e CFC-12 na baixa atmosfera em regiões remotas, rurais e urbanas no Brasil. / Study of the chlorofluorocarbons 11 and 12 in the lower atmosphere in remote, rural and urban areas in Brazil.
ABSTRACT Chlorofluorocarbons (CFCs) were intensively used for refrigeration, production of aerosols and foams. Presently, their production and trade are controlled, because of their role in ozone depletion. This work presents a study of atmospheric chlorofluorocarbons CCl3F (CFC-11) and CCl2F2 (CFC-12) in the lower troposphere of remote regions in Brazil (Ba
