The impact of winter addition of salts to roadside soils was studied for the national road No. 28 in Poland, in Małopolska Region. The measured sections of the road No. 28 are two access ways to the city of Grybów. According to instructions of GDDiKA (General Directorate for National Roads and Motorways) both sampled routes: Grybów–Gorlice (sampling section G-G) and the section Nowy Sącz-Grybów (N-G) were included in II standard of winter road maintenance. The general increase in soil salinity, chloride concentration and pH values from the roadside soils was evidenced by the difference of results of two sampling campaigns, before and after winter season of 2015/16. Salinity indicators showed significant increase, even though weather winter season 2015/16 was rated as mild and road de-icing salts were applied at less-than-average rate. Soil hydraulic properties were calculated estimated from soil texture using pedo-transfer functions for estimating the dynamics of salts into soils, suggesting easy leaching of salts from topsoil.

W pracy przedstawiono wyniki badań zawartości wybranych metali ciężkich (Pb, Cd, Sr, Zn, Cu, Ni, Mn, Cr) w odpadach posodowych zdeponowanych na osadnikach byłych KZS Solvay oraz w nadkładzie glebowym przykrywającym te osadniki. Celem badań było określenie zawartości metali ciężkich oraz współzależności zachodzących między zawartością metali cięż- kich a pozostałymi parametrami osadu.

This paper presents the results of a study on the content of selected heavy metals (Pb, Cd, Sr, Zn, Cu, Ni, Mn, Cr) in sodium waste deposited on the sett ling tanks of the former “Solvay” Krakow Soda Works and in the soil overburden covering the settling tanks. The aim of the study was to determine the content of heavy metals, their correlations and relation between heavy metals and some parameters of the sediment.
