“…Analysis of REE+Y concentrations were performed by employing two single-collector ICP-SFMS instruments (ELEMENT XR and ELEMENT 2, Thermo Fisher Scientific, Bremen, Germany) based on the protocol documented in Rodushkin et al (2018). Cation exchange resin AG 50W-X8 (200 to 400 dry mesh size, Bio-Rad laboratory AB, Solna, Sweden) was used for preconcentration of REE+Y.…”

The elevated concentrations of rare earth elements (REE) and yttrium (REE+Y) in acid mine drainage (AMD) constitute an opportunity for REE+Y recovery.However, the source and control of REE+Y signatures in AMD remains uncertain.Water, rock, sediment and sludge samples were collected from an ion-adsorption rare earth mining area to investigate REE+Y concentration and fractionation patterns in AMD. High concentrations of REE+Y occur in the pristine mine water (MW), and decrease progressively with MW passing through nitrification-denitrification (NDT) and coagulating-precipitation (CPT) treatment procedures in a water treatment plant.Concentrations of REE+Y are 1 to 3 orders of magnitude higher in MW, NDT and CPT samples than those in well water (WW), and are negatively correlated (R 2 0.72) with pH (3.8 to 8.7), suggesting that an enhanced acidic dissolution of minerals contributes REE+Y to AMD from the source area. Speciation calculation indicates that REE+Y are mainly free ions and sulfate complexes in MW and NDT samples, while carbonato and dicarbonato complexes in CPT samples. Normalized REE+Y patterns of water samples show a coherent enrichment of heavy REE (HREE) over light REE (LREE) and negative Ce anomalies. HREE-enriched patterns and Ce anomalies are kept relatively constant in MW, NDT and CPT samples, despite their huge disparity in REE+Y concentrations, indicating a limited impact of preferential precipitation of LREE over HREE on REE+Y fractionations. The HREE-enriched patterns possessed by AMD are similar to those of sediment samples, while are distinct from whole rocks. These behaviors suggest a major role of sediment source in controlling REE+Y concentrations and patterns in AMD. Results of XRD show abundance of muscovite, kaolinite and feldspar in sediments. Combining to SEM-EDS examinations, minerals such as kaolinite, schwertmannite (Fe16O16(SO4)3(OH)6(H2O)10•10H2O) and ferrihydrite are suggested to be the main hosts of REE+Y in sediments. Hence, HREE-enriched patterns of AMD result from preferential leaching of HREE from sediments which accumulate REE+Y after being initially mobilized from rocks under the conditions prevailing in mine site. The free form and sulfate complexation preserves REE+Y patterns and facilitates REE+Y mobility in the AMD system. Based on the plant treatment capacity, the potentially recoverable LREE and HREE are

“…Since the only sample treatment used was dilution, and the dilution factors were multi-fold, it was deemed obligatory to run blank analyses for evaluating contamination or spectral interference effects (with complex matrices, not all interferences could be separated, even when using the SF technique 4 ). The precision of the method was determined by analyzing the CASS-6 CRM on three different days (the data summarized in Table 3).…”

In this study, new insights into the contamination of marine ecosystems are provided by the simultaneous analysis of concurrently collected bottom seawater and upper sediment layer samples with inductively coupled plasma mass spectrometry (ICP-MS). Precise and interference-free quantification of the trace levels of selected heavy metals in seawater diluted 100 times was directly obtained by high-resolution ICP-MS, with the recovery (from 94 to 109% against the certified reference material CASS-6), repeatability (3-5%), intermediate precision (averaging 6.5%), and limits of detection (0.002-0.3 µg L -1 ) being systematically assessed. The same metal contaminants accumulated in the surface sediments were determined -after sample digestion prior to measurements -by quadrupole ICP-MS using a previously optimized and validated protocol. Both sets of metal concentration data expressed as a function of distance from the coast show a decline, followed by a flattening where the transfer of insoluble material and the associated metal fluxes carried by the river watercourse tend to end an action. This occurrence was confirmed by quantifying the natural seawater constituents, such as potassium and lithium, whose concentrations remained constant after the distance of 250 km from the estuary due to a reduced dilution by freshwater.

Hydrochemical Characteristics and Evolution Mode of Cold Seeps in the Qiongdongnan Basin, South China Sea

Submarine cold seeps have recently attracted significant attention and are among the most effective indicators of gas hydrate in the oceans. In this study, remotely operated vehicle (ROV) observations, seismic profiles, core sediments, bottom seawater, and fluid vented from cold seeps in the deep-water Qiongdongnan Basin were used to investigate the origin and evolution of cold seeps and their relationships with gas hydrate. At stations A, B, and C, inactive cold seeps with dead clams, cold seep leakage with live clams, and active cold seeps with a rich mussel presence, respectively, were observed. The salinity and Na+ and Cl- concentrations of the cold seeps were different from those of typical seawater owing to gas hydrate formation and decomposition and fluid originating from various depths. The main ion concentrations of the bottom seawater at stations B and C were higher than those at station A, indicating the substantial effects of low-salinity cold seep fluids from gas hydrate decomposition. The Na+-Cl-, K+-Cl-, Mg2+-Cl-, and Ca2+-Cl- diagrams and rare earth element distribution curves of the water samples were strongly affected by seawater. The concentrations of trace elements and their ratios to Cl- in the bottom seawater were high at the stations with cold seeps, suggesting the mixing of other fluids rich in those elements. Biochemical reactions may also have caused the chemical anomalies. Samples of HM-ROV-1 indicated a greater effect of upward cold seep fluids with higher B/Cl-, Sr/Cl-, and Ba/Cl- values. Moreover, the Re/Cl- value varied between fluid vents, possibly due to differences in Re precipitation strength. Differences in cold seep intensity are also believed to occur between areas. The cold seep fluxes changed from large to small before finally disappearing, showing a close connection with gas hydrate formation and decomposition, and influenced the local topography and ecosystems.
