ABSTRACT
This paper presents results of the determination of the total concentration of arsenic, antimony and selenium and their inorganic speciation forms in water samples from grate ashes dumping grounds. Determined concentrations of elements were up to 128.8 ng/mL for arsenic, 153.7 ng/mL for antimony and 52.9 ng/mL for selenium, at the detection limits of 0.16 ng/mL for As, 0.18 ng/mL for Sb and 0.15 ng/mL for Se. Water from some study sites was characterized by very high concentrations of determined elements, which were used to follow their migration. Leakage of dangerous micro-pollutants to ground water was stated. Based on results of speciation analysis the vertical migration of pollutants through unsaturated zone was found.
