The fluoride emission by an aluminum industry was estimated by the fluoride concentration in eucalyptus leaves (Eucalyptus grandis x Eucalyptus urophylla) located at distances of up to 1,700 m from the industry in Alumínio, SP, and Capão Bonito, SP, 150 km from the factory. The fluoride concentration in the aqueous extract of leaves of six trees was determined by specific ion electrode. The average concentrations (mg F/kg) found in Alumínio were up to 100 times higher than those of Capão Bonito. It is concluded that there is environmental pollution by fluoride in the Alumínio city.
