Abstract

Mercury presence in mining areas is of environmental concern due to the potential risk associated to its mobiliza- tion and drift toward adjacent areas. In this study, total Hg content (HgT) was determined in 46 soil samples col- lected in the surroundings of a former mine zone, where a Pb-Zn deposit was subjected to extraction activities in Rubiais (NW Spain). Total Hg in soil samples ranged from 1.2 to 28.6 mg kg-1, being above the generic reference levels for this element in Galician soils as well as being higher than the critical Hg load established for soils (0.13 mg kg-1). The high total Hg values detected suggest the necessity to carry out a detailed assessment of risks of being mobilized to the nearby areas, and the subsequent impact on the biotic and abiotic components of the eco- systems located in the area.
