Abstract

Changes in the content of mineral nutrients (Ca, Mg, K, Na) and risk elements (Mn, Cd) in the assimilatory organs of selected plant species were studied along the altitudinal gradient of A‒D zones polluted by alkaline emissions from the magnesite factory Lubeník (Slovak Republic). Multivariate statistical analysis and comparison with background values in other studies demonstrate persistent intoxication of some plants by Mg (all study plants), K (Lactuca saligna, Dryopteris filix-mas), Mn (Quercus polycarpa, Carpinus betulus, Betula pendula, Lactuca saligna) and Cd (Quercus polycarpa, Carpinus betulus, Betula pendula, Lactuca saligna). Overall, Lactuca saligna accumulated the highest amounts of Mg, Cd, Na and K near the magnesite plant, suggesting its potential as an effective bioindicator of elemental pollution. Unbalanced Ca/Mg ratios, lower than 1, were recorded predominantly in all plant species sampled near the magnesite plant; unbalanced K/(Mg + Ca) ratios were predominantly in woody species.
