    In a tannery, the area that presents most contamination by odors emanating due to organic and inorganic chemical compounds is the waste disposal area where mainly remains of bait are degradated. Its decomposition generate pollution in the air affecting the health of people who are close to this area, between workers and inhabitants of the sector. The evaluation of odors in the waste disposal area was performed by a literature research where chemical compounds that cause most damage to individuals were identified, between which ammonia, hydrogen sulphide and volatile organic compounds were analyze being the most representative nitrobenzene and mercaptans. Multiple gas monitor IBRID MX6 was used in the waste disposal area to measure the concentration of chemical compounds in ppm and calculate the dose of each chemical compound, which were above the permissible limits according to INSHT, especially nitrobenzene that presented concentrations well above permissible levels, since there is no method of control to minimize the emission of the same. The technique that was used to reduce emissions to the environment of chemicals was the installation of an HDPE geomembrane in the disposal area due to its properties. Subsequent measurements were carried out again resulting in a significantly lower concentration of all chemical compounds whose dose now lies within the permissible limits.
