MIRLEAN, Nicolai; CASARTELLI, Maria R.  and  GARCIA, Marina R. D.. Propagation of airborne fluorine contamination on groundwater and soil near fertilizer factories in Rio Grande (RS). Quím. Nova [online]. 2002, vol.25, n.2, pp.191-195. ISSN 0100-4042.

Fluoride concentration was determined in rainwater, ground water and soil in the zone of fertilizer industry in the city of Rio Grande. In contaminated rainwater fluorine concentration was registered up to the value of 4,4 mg.L-1. Fluorine concentration in the shallow ground water in general reflects its distribution in the atmosphere, but cannot be used as marker of atmosphere contamination in the urban area due to dissolving influence of residential effluents. The 0,01% HCl extracts from the set of surface soil samples demonstrates fluoride distribution in the zone of influence of industrial emissions, which coincides to the numerical simulation of fluorides dispersion in the air.

Keywords : fertilizer industry; fluorine distribution; environmental pollution.
