| Abstract Scope |
The clay mineral extraction activity for the production of ceramic artifacts generates huge problems related to degraded areas. The objective of this research was a physical, chemical, mineralogical and environmental characterization of different soils from regions degraded by the mining activity, located in the municipality of Campos dos Goytacazes, RJ, Brazil. Soils were collected and characterized according to their technological and environmental parameters in order to compare their results to the limits proposed by the literature and the Brazilian standard, and to verify the potential environmental problem that occurred. The results showed that in all samples evaluated there was the presence of contaminants from the exposure of clayey material to weathering and potential damage from exposure to the water table, in addition to diesel oil from leaks from the tanks of trucks that worked in the clay extraction, causing changes in the results of chemical characterization of the samples. |
