Resumen

SILVA, María José  y  SALINAS MORALES, Diego. Contamination from the tannery industry, an approach to the Ecuadorian reality. RCUISRAEL [online]. 2022, vol.9, n.1, pp.69-80.  Epub 10-Abr-2022. ISSN 2631-2786.  https://doi.org/10.35290/rcui.v9n1.2022.427.

This article focused on describing the typical processes, materials used, main health risks derived from the leather tanning industry, as well as the environmental impact associated with this industry and activity in the province of Tungurahua, Ecuador. For the development of this document, an integrative review of the literature was carried out, as a bibliographic research modality. The main result was that the contamination of water tributaries with chemicals from wastewater, resulting from the transformation of animal skins into leather for the leather goods industry, has determined the exponential growth of contamination, due to the poor management of such waste. Contamination of water resources is evidenced by the amount of chromium discharged into the water, both trivalent and hexavalent. The concentration of Cr6 ranges from 52.3 to 392.9 mg/L, exceeding the limit determined by the TULAS regulations. It is concluded that the determination of Cr6 becomes a potential factor and an imminent risk for the development of different affectations associated with chromium exposure.

Palabras clave : tannery; tanneries; contamination; chromium; environmental management; animal skins.
