“…In the field of geochemistry, sequential extraction has proven its value. Nevertheless, accuracy at every stage of sample processing and analysis is crucial to guarantee an acceptable level for detecting (LOD-limit of detection) and quantifying the analytes [91]. TMs may be determined by commonly used instruments such as flame (FAAS), hydride generation (HGAAS), and electrometry (ETAAS) atomic absorption spectrometry, as well as inductively coupled plasma mass spectrometry (ICP-MS) and emission spectrometry (ICP-OES).…”

This paper provides an overview of different methods of assessing the trace metal (TM) contamination status of sediments affected by anthropogenic interference. The geochemical background determination methods are also described. A total of 25 papers covering rivers, lakes, and retention tanks sediments in areas subjected to anthropogenic pressure from the last three years (2019, 2020, and 2021) were analysed to support our examination of the assessment measures. Geochemical and ecotoxicological classifications are presented that may prove useful for sediment evaluation. Among the geochemical indices, several individual pollution indices (CF, Igeo, EF, Pi (SPI), PTT), complex pollution indices (PLI, Cdeg, mCdeg, Pisum, PIAvg, PIaAvg, PIN, PIProd, PIapProd, PIvectorM, PINemerow, IntPI, MPI), and geochemical classifications are compared. The ecotoxicological assessment includes an overview of Sediment Quality Guidelines (SQG) and classifications introduced nationally (as LAWA or modified LAWA). The ecotoxicological indices presented in this review cover individual (ERi) and complex indices (CSI, SPI, RAC, PERI, MERMQ). Biomonitoring of contaminated sites based on plant bioindicators is extensively explored as an indirect method for evaluating pollution sites. The most commonly used indices in the reviewed papers were Igeo, EF, and CF. Many authors referred to ecotoxicological assessment via SQG. Moreover, PERI, which includes the toxic response index, was just as popular. The most recognised bioindicators include the Phragmites and Salix species. Phragmites can be considered for Fe, Cu, Cd, and Ni bioindication in sites, while Salix hybrid cultivars such as Klara may be considered for phytostabilisation and rhizofiltration due to higher Cu, Zn, and Ni accumulation in roots. Vetiveria zizanoides demonstrated resistance to As stress and feasibility for the remediation of As. Moreover, bioindicators offer a feasible tool for recovering valuable elements for the development of a circular economy (e.g., rare earth elements).

“…The first (157 references) focussed 59 on the use of MOFs (a type of coordination polymer with an inorganic metal centre surrounded by organic ligands) as specific adsorbents for trace elements in environmental and food matrices. The second review (146 references) covered 60 sample preservation, storage and extraction techniques for the elemental speciation analysis of environmental samples.…”

“…[9][10][11][12] Different methods and analytical techniques such as chemical treatment, 13 electrochemistry, 14 Xray uorescence, 15,16 inductively coupled plasma atomic/optical emission spectrometry 17,18 and inductively coupled plasma mass spectrometry 19,20 have been widely used for the analysis of Hg(II), however, direct determination of Hg(II) in real aqueous samples is challenging due to its very low concentrations with complex sample matrices. 21,22 The sample matrices compromise the instrumental detection, accuracy and the limit of quantication. 23,24 Nevertheless, this can be eliminated by sample pretreatment before analysis and thus, an extraction and preconcentration step is oen pre-requisite to instrumental determination.…”
