Sažetak
Soil and giant goldenrod (Solidago gigantea Ait.) samples were collected in June and July 2014 on 25 localities in northwestern Croatia alongside railroad lines Zagreb-Varaždin, Varaždin-Golubovec and Varaždin-Ludbreg. The aim of this research was to investigate the phytoaccumulation potential of giant goldenrod on surfaces affected by railway transport for the following heavy metals: Cd, Cr, Cu, Ni, Pb and Zn. Total concentrations of heavy metals in soil and plant samples were determined by a high resolution inductively coupled plasma mass spectrometry (HR-ICP-MS) method. The results of the analysis showed the following: goldenrod samples contained the highest average concentration of Zn (27.0 mg/kg, d.w.), followed by Cu (6.36 mg/kg, d.w.), Cr (1.54 mg/kg, d.w.), Ni (0.844 mg/kg, d.w.), Pb (0.544 mg/kg, d.w.) and Cd (0.068 mg/kg, d.w.). Phytoaccumulation coefficients, which show how successfully a plant removes certain pollutants from the environment, were calculated from the mass concentrations of heavy metals in plant and soil samples. The average phytoaccumulation coefficients for goldenrod were the following: for Zn (0.215), for Cd (0.185), for Cu (0.180), for Cr (0.023), for Ni (0.023) and for Pb (0.017). According to the literature, phytoaccumulation coefficients of plant species suitable for phytoremediation should be greater than 1. However, goldenrod has several advantages in comparison with other plants hyperaccumulators which should be considered. Goldenrod creates large biomass per unit area during the vegetation season and stands cover large areas of abandoned arable land, meadows and similar habitats in continental Croatia. Also, goldenrod is an invasive species in Croatian flora and its removal by mowing, alongside heavy metal phytoremediation, would be also desirable from the aspect of nature protection, as this creates conditions for the restoration of autochthonous vegetation.
