MINDIOLA, MÍRLEY; PEDRAZA, JULIO  e  ESCALANTE, HUMBERTO. CONTAMINATION CHARGE INDEX FOR THE WASTEWATER PRODUCED DURING THE GOLD AND SILVER CHEMICAL REFINEMENT PROCESS IN THE JEWELRY WORKSHOP OF BUCARAMANGA. Dyna rev.fac.nac.minas [online]. 2008, vol.75, n.156, pp.135-146. ISSN 0012-7353.

The objective of the present work was to evaluate the polluting load of the liquid effluents of the process of chemical gold refinement and silver with nitric acid, that factories of jewelry shop in Bucaramanga and their metropolitan area generate, and that without no type of previous treatment are spilled to the sewage system network I publish. For such aim a tool was designed to calculate an Index of Polluting Load (ICC), that allows to value qualitatively as much as quantitatively the contamination generated by these wastewater. With the calculation of the ICC the group of factories in study was located in a rank of very bad qualification between and terrible environmental quality, corroborating the hypothesis that this industrial sector needs urgent way a treatment of remediation for its spills.
