The main objective of this research is on the chromium used in tanning, which is considered one of the most toxic metals, but the main one for transforming animal skin into a noble article, leather. Due to the need and care for the environment, we carried out analyzes of the chromium content present in the industrial effluent after the process and the percentage present in the soil after receiving this effluent through fertigation. Taking into account our main objective, which is to verify whether the company respects environmental standards, complying with the requirements of its environmental license on the correct disposal of effluents on land, without contamination and destruction of the area.
