Wolf (Finland) was used as a phytoremediant and was cultivated on the contaminated territory of the mining enterprise – the tailing dump (the main pollutants being Ni and Fe). <...> After one year, the willow plant samples were divided into two groups: healthy plants with higher biomass production (HBP) and suppressed plants with lower biomass production (LBP). <...> The root system of HBP and LBP plants had no differences, but aboveground biomass was higher in HBP willow plants. <...> SLA index (specific leaf area) was 1.53 mm2 mg–1 and 1.21 mm2 mg–1 in HBP and LBP groups, correspondingly. <...> Keywords: Salix schwerinii, phytoremediation, heavy metals, photosynthetic pigments, biometric parameters, specific leaf area, joint stock company «Karelsky Okatysh», Republic of Karelia. <...> How to cite: Terebova E.

Potential for Salix schwerinii Е. <...> The development of modern mining and metallurgical industry with high level of emissions into the atmosphere of acidifying substances and heavy metals, leads to the degradation of terrestrial ecosystems of adjacent territories and formation of industrial barrens (Lukina, Nikonov, 1998; Remon et al., 2005; Kozlov, Zvereva, 2007). <...> The predominant part of the industrial barrens is located in the © Terebova E.
