ResumoThe concentrations of toxic metals in soils have continuously increased as a result of anthropogenic activities through inputs mainly from mining, municipal wastes, road traffic or fuel burning. In addition to their toxicity, metals persist in soil for long times and have the capacity to be transferred into the food chain, thus the assessment of their content in soil is of great interest. Scandium, the Mendeleev's hypothetical element eka- boron is considered one of the Rare Earth Elements (REE) group, in abundance in the earth's crust of 16 ppm. REEs are required in industry, agriculture, medicine, biotechnology and many other fields. The aim of the study was the analysis by atomic fluorescence X-ray of the scandium content in soil, in a polluted area (Tarnaveni, Mures county, Romania). Tarnaveni was an important industrial centre. Seven locations were taken into our study. The analysis of experimental data highlights high values of scandium content in the soil samples. The highest scandium concentrations were found in the locations close to the chemicals waste. The preliminary results can be used as informative data that they will be confirmed by further analysis by absorption atomic spectrometry method (FAAS).
