摘要：

Ore-bearing rocks and natural waters of the Pitkaranta ore district (near the "Arsenic" shaft, the Hopunvaara mine field) were sampled and analyzed. The permanganate value as well as iron and manganese contents in surface water are higher than MPC values, while water samples from the "Arsenic" shaft have the elevated contents of zinc, copper, and arsenic. The Fe, Mn, Cu, Zn, Cr, As, and Ni speciation in waters have been determined by thermodynamic calculations, taking into account the possibility of the formation of metal complexes with humic and fulvic acids. The fulvic acid is almost completely consumed for the formation of the complex Fe(OH)(2)Fu(-). Ni, Cd, Co occur mainly in the ionic form, and the fraction of Mn and Zn in the ionic form is also significant.
