The gold mining activity performed in the past in Romania has led to the pollution of the environment, the degradation of large areas of land and currently represents a significant risk to human health. As a result of the gold mining activities performed in Almasu Mare area, there were large sterile dumps and gold mine galleries that continue to give their mark on the quality of the environment and human health through the amount of heavy metals in the soil and the sterile material improperly deposited, the water that comes out of the underground to the contaminated surface and which flows into the rivers in an uncontrolled way. This paper brings details of cadmium soil pollution in the studied area. The results obtained in the analysis of cadmium concentrations through the AAS spectrometry show that the analysed soil exceeds the admissible limits provided by the legislation in force, and the sterile material collected from the sterile dumps reflects values of the Cd concentration in the interval 10.7 – 22.6 mg/kg. Due to the high concentrations present in the soil and sterile material analysed, soil remediation interventions are required in the area.
