“…The toxicity of Lu 3+ is higher than those of Cd 2+ and Zn 2+ but comparable to that of Cu 2+ . Adverse effects of Lu occurred at concentrations that exceed natural surface water levels by 2-3 orders of magnitude (15). Compared to the EC50 of La, the lightest lanthanide, Lu is 200 times more toxic.…”

“…Best studied are iron (13) and aluminum (14), but application of the FIM has never been described for elements of the lanthanide series. The lanthanides, ranging from lanthanum (La, Z ) 57) to lutetium (Lu, Z ) 71), comprise 15 homologous trivalent metals, of which 14 commonly occur in nature (15). Industrial uses and applications of lanthanides are still increasing (16) and so are the accompanying emissions to the environment.…”

The validity of the free-ion model (FIM) for the element lutetium (Lu), a member of the lanthanides, was assessed in experiments with the bacterium Vibrio fischeri. The FIM is mainly based on divalent metals and synthetic ligands and has not yet been validated for the trivalent lanthanides. The bioluminescence response of V. fischeri was studied at different Lu concentrations in the presence and absence of natural and synthetic organic ligands [citrate, malate, oxalate, acetate, ethylenediaminetetraacetate (EDTA), and nitrilotriacetate (NTA)]. All ligands were tested separately to ensure that their concentrations would not cause adverse effects themselves. Free Lu 3+ concentrations were calculated with a speciation program, after extension of its database with the relevant Lu equilibria. The results confirmed the FIM for Lu: that is, in contrast to total dissolved Lu concentrations, free Lu 3+ concentrations had an apparent relationship with the response of V. fischeri. However, a contribution of minor inorganic Lu complexes cannot be ruled out. In the presence of malate and oxalate, the EC 50 for Lu 3+ decreased faster in time than for the other ligands, indicating lower elimination rates. With an EC 50 of 1.57 µM, Lu 3+ is more toxic than La 3+ , Cd 2+ , or Zn 2+ and approximately equally as toxic as Cu 2+ . Although the pH increased slightly during the experiments, it was shown that the influence of pH on Lu speciation was limited.

“…The typical approach employed in environmental investigations of trace elements in biological materials and organisms aims to assess trace element bioaccumulation (Weltje et al, 2002). This can be evaluated according to the amplitude of the bioaccumulation factor (BAF), which is defined as the concentration ratio for each investigated element i in the studied sample (sa) and environmental medium (env):…”

“…Determination of rare earths from various types of environmental samples is particularly important because it can serve to establish a sample fingerprint, and thus, the results could be used in determining the origin of the concerned sample and to identify sources of pollution [15,16]. Mass spectrometry with inductively coupled plasma offers the possibility to measure the rare earths with an excellent accuracy, which cannot be achieved by any another method [17,18].…”

A study was carried out to determine the accumulation of trace metals in water, sediments, and soil from several locations in the Transylvania region (Romania), using the inductively coupled plasma mass spectrometry (ICP-MS) technique. A significant number of metals (range of several μgL −1 ) were identified, the toxic metal concentrations in mostly of the investigated waters being within the permissible limits. A seasonal variation in the metal content was also observed. Comparison of the metal concentrations to samples of sediment, soil, and vegetation coming from the surrounding areas of the same water reservoir revealed a higher accumulation of rare and toxic metals in sediments than in soil and vegetation.
