大量含有难以想象的有毒金属(loid)的采矿和冶金废物需要寻找管理方法。这项研究旨在长期评估增长,元素积累(As,Cd,Hg,In,Mn,Mo,Pb,Sb,Sn,Ti,Tl,2岁的TiliacordataMill中的Zn)和脯氨酸含量。在1、2和3年后,在1%和3%的极端污染的采矿污泥(MS)下生长。两种物种都能够有效地生长,而MS的影响没有显着差异。T.cordata的整体涨幅高于Q.robur。对As的积累能力,Hg,In,Mn,Mo,Pb,Ti,整个植物中的锌明显高于T.cordata,而Cd,Sb,Sn和Tl在物种之间没有显著差异。含量最高的是As,锰和锌(每株68.7、158和157毫克,分别)为T.cordata生长3年后。计算的生物富集因子是最高的Cu(1.23),在(6.86)中,和锌(38.4)为Q.robur,以及As(1.55),汞(3.24),Mn(32.8),3年后T.cordata的Mo(1.64)和Ti(18.0)。3年后,In(1.35)和Sn(1.25)的易位因子最高,以及Q.Robur幼苗的Mn(1、2和3年后的2.72、3.38和3.03)。Q.robur的脯氨酸含量较高,不管检查哪个器官,并且差异随着实验时间和MS添加量的增加而增加(可能对压力更敏感)。幼小的T.cordata幼苗比Q.robur显示出更大的潜力。这是首次描述了长寿树木在多元素MS修复中的高潜力。
The vast amounts of mining and metallurgical wastes containing unimaginable quantities of toxic metal(loid)s require searching for managed ways. The study aimed to long-term assess the growth, elements accumulation (As, Cd, Hg, In, Mn, Mo, Pb, Sb, Sn, Ti, Tl, Zn) and proline content in 2-year-old Tilia cordata Mill. and Quercus robur L. seedlings growing under 1 and 3% extremely polluted mining sludge (MS) after 1, 2 and 3 years. Both species were able to grow efficiently without significant differences resulting from the impact of MS. The overall rise was higher for T. cordata than for Q. robur. The accumulation ability for As, Hg, In, Mn, Mo, Pb, Ti, and Zn in the whole plant was significantly higher for T. cordata, while Cd, Sb, Sn and Tl did not differ considerably between species. The highest content was found for As, Mn and Zn (68.7, 158, and 157 mg per plant, respectively) for T. cordata after 3 years of growth. The calculated Bioconcentration Factors were the highest for Cu (1.23), In (6.86), and Zn (38.4) for Q. robur, as well as for As (1.55), Hg (3.24), Mn (32.8), Mo (1.64) and Ti (18.0) for T. cordata after 3 years. The highest Translocation Factors were observed for In (1.35) and Sn (1.25) after 3 years, as well as for Mn (2.72, 3.38, and 3.03 after 1, 2, and 3 years) for Q. robur seedlings. The proline content was higher for Q. robur, regardless of which organ was examined, and the differences increased with the time of the experiment and the amount of MS addition (possibly more sensitive to stress). Young T. cordata seedlings show much greater potential than Q. robur. This is the first time that a demonstration of the high potential of long-living trees in multi-element MS remediation has been described.
