Abstract: The phytoremediation of polluted land in Romania is based on research on biodiversity, environmental protection, and the sustainable use of natural or man-made resources, carried out by universities and research institutes for over 30 years, synchronized with those at the European and global level. The aim of this paper is to establish the categories of pollutants with potential environmental, economic, and social impacts associated with mining in order to choose the optimal method of ecological reconstruction. In this regard, the Tismana quarry was mapped, the surface of the analysis plot was set at 50 m × 50 m, and the sampling depth was 0–20 cm; from each plot, two samples were collected. Out of a total of 121 analysis plots, ten susceptible plots were identified, from which 20 samples were collected and analyzed. The samples were analyzed by the UV-VIS spectrophotometer method—MLUV1720 and UV spectrometry—with a SHIMADZU UV 160U spectrophotometer; they indicated in only three analysis plots a pollution with phenols, Ni, Zn, Ni and HAP, the concentrations of which exceeded only the normal values, which does not affect the eaves threshold and intervention for the type of land use. Being point pollution, the phytoremediation of these soils can be achieved in a short time. The paper aims to present the situation of chemical pollutants in the Tismana quarry area, and to offer different ecological rehabilitation solutions depending on their presence.
