Acesso em:.https://repositorio.ufpa.br/handle/2011/14902The aluminum industry is considered one of the main sources of industrial contamination by fluoride, which generates atmospheric pollution. In this research, a quantitative assessment of the distribution of fluoride in the various environmental compartments in the area of ​​influence of the ALBRÁS/ALUNORTE Industrial Complex, located in the municipality of Barcarena (PA). For this purpose, chemical analyzes of total fluorine were carried out in soils, plants and waters. In the soils, complementary analyzes of Al, Fe, Ca and Mg, determination of pH and mineralogical composition were also carried out. In addition to the data obtained in laboratories, those made available by the ALBRÁS aluminum factory were also used. For the interpretation of the data, geostatistical techniques and visual analysis of isoteor maps were used, which allowed observing the distribution, albeit in a preliminary way, of fluorine levels in soils, groundwater and grasses. It was verified that there is an impact of the industry on the environment, in its area of ​​influence, evidenced by the increase of contents with time and by the “concentric” distribution of the levels of fluoride found.Acesso AbertoAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/FlúorPoluiçãoPoluentesIndústria de alumínioAlbrásBarcarena (PA)AmazôniaDissertaçãoCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS::GEOLOGIAMINERALOGIA E GEOQUÍMICAGEOQUÍMICA E PETROLOGIA
