CONCENTRATION OF HEAVY METALS IN THE SNOW COVER AROUND OSTROWIEC ŚWIĘTOKRZYSKI


Concentration of selected heavy metals (Pb, Cd, Co, Cr, Cu, Mn, Ni, Zn, Al, Fe) was analysed in water samples from melted snow collected in the surroundings of steel plant in Ostrowiec Świętokrzyski. The plant was in the centre of research area and the samples were collected along the north-south and east-west axes. The total of 18 samples were collected on 31.1.2017, when the snow cover was present for over four weeks, absorbing metallurgical dust containing the analysed heavy metals. Concentrations of dissolved metals were measured with the use of mass spectrometer ICP/MS-TOF. The highest mean concentrations were noted for iron (62.50 μg·dm-3), zinc (57.14 μg·dm-3), manganese (15.51 μg·dm-3), aluminium (8.10 μg·dm-3) and copper (1.72 μg·dm-3). The concentrations of lead, cadmium, cobalt and nickel were lower than 1 μg·dm-3. The results, including chemical composition and spatial distribution of metal concentrations in snow samples, indicate a strong impact of atmospheric pollution emitted from the steel plant in Ostrowiec Świętokrzyski on the surrounding area.
