“…In the above mentioned but also other papers, with the exception of PGE, the same elements (Cd, Cr, Cu, Pb, and Zn) have been analyzed in different plant species. Among numerous herbaceous species, Taraxacum officinale (Keane et al 2001 ) and Achillea millefolium L. (Modlingerová et al 2012 ) have been the most frequently analyzed. However, to date the phytoremediative potential of Artemisia vulgaris L. and Trifolium repens L. have been estimated only for As, Cd, Cu, Ni, Pb, and Zn (Kafoor and Kasra 2014 ; Çolak et al 2016 ); Cu, Hg, and Pb (Pivić et al 2013 ); As, Cd, Cr, Cu, Mo, Ni, Pb, and Zn (Modlingerová et al 2012 ); or As, Pb and Sb (Álvarez-Ayuso et al 2012 ).…”
