Special Issue Information

Dear Colleagues,

Heavy metals, metalloids and organic pollutions in water may originate from both natural (mineral weathering) and anthropogenic sources (industrial activities, household and hospitals effluents, atmospheric deposition, and traffic related emissions). In recent years, in connection with the development of our society and technological progress, new inorganic and organic contaminants, such as platinum group metals (PGM), rare earth elements (REE), metal nanoparticles, pharmaceuticals, pesticides, personal care products are introduced into water. In water environment these pollutants may be present in dissolved forms  as well as accumulated in the bottom sediments. Despite their low concentrations in the aquatic environment, frequent exposure to them may create a risk to aquatic organisms and human health. Determination of trace metals, metalloids and organic pollutants in water is essential for the evaluation of water quality. Studies on the behaviour and transformations of inorganic and organic pollutants in aquatic environment are crucial to understand their eco-toxicity. For this purpose, the development of interference free analytical methods with good sensitivity and accuracy is still necessary.

In light of the above, we would like to call for papers presenting recent innovative developments within the field of determination of trace metals, metalloids and organic pollutants in water. This special issue of Water is addressed, but not limited to, the following research areas:

  • heavy and toxic metals and metalloids in natural and drinking waters, new contaminants as e.g., metal nanoparticles, PGM, REE;
  • organic pollutants as e.g., pharmaceuticals, pesticides, personal care products in natural and drinking water;
  • development in sample preparation methods, separation and pre-concentration of analytes from interfering matrix;

  • advances in determination of these pollutants by spectrometric, voltammetric, chromatographic and other determination methods (including coupled techniques);
  • speciation of metals and metalloids in waters;
  • quality assurance and quality control in water analysis.

This study assessed the spatiotemporal variability and pollution grades of heavy metals in water and sediments of Bahr El-Baqar drain, Eastern Nile Delta, Egypt, by integration of geochemical analysis, metal pollution indices, correlation, and multivariate statistical analyses. Twenty samples of water and sediments were collected during 2018 and analyzed for heavy metal concentrations using ICP-OES. Heavy metal contents in the water samples followed the order: Fe > Zn > Al > Pb > Mn > Cu > Ni. The drain sediments were highly contaminated with heavy metals that followed the order: Fe > Al > Mn > V > Zn > Cu > Cr > Ba > Ni > Pb > As. Spatiotemporally, most metals in the drain sediments showed a decreasing trend from upstream (south) to downstream sites (north). Results of principal component analysis (PCA) supported those from the Pearson correlation between investigated heavy metals. In water, Mn, Ni, Pb, Zn, Cu, and Fe showed highly significant correlations. In sediments, Ba, Ni, Zn, Fe, Al, Mn, and V showed strong positive correlations indicating that these metals were derived from similar anthropogenic sources. The calculated metal pollution indices: enrichment factor (EF), contamination factor (CF), pollution load index (PLI), degree of contamination (DC), and index of geo-accumulation (Igeo) indicated high loadings of heavy metals in the drain sediments. EFs revealed low, moderate to significant enrichment, whereas CFs showed low, moderate, and considerable contamination. PLI indicated low, baseline, and progressive contamination, while DC indicated low, moderate, and considerable degree of contamination. Igeo of all investigated metals (except for As; class 1) indicated extremely contaminated sediments (class 7). Full article

In this work, a new solid phase extraction method for the determination of chromium species in water samples by electrothermal atomic absorption spectrometry was developed. For selective separation of Cr(III) ions under dynamic conditions, two ion imprinted polymers containing Cr(III)-1,10-phenanthroline complex (Cr(III)-phen) were prepared with the use of one (styrene, ST) or two (styrene and 4-vinylpyridine, ST-4VP) functional monomers. The physicochemical properties of those solid sorbents towards Cr(III) ions were studied and compared. It was found that Cr(III) ions were retained on the Cr(III)-phen-ST and Cr(III)-phen-ST-4VP polymers with high efficiency and repeatability (91.6% and 92.9%, RSD < 2%) from solutions at pH 4.5. The quantitative recovery of the analyte (91.7% and 93.9%, RSD < 4%) was obtained with 0.1 mol/L EDTA solution. The introduction of 4VP, an additional functional monomer, improved selectivity of the Cr(III)-phen-ST-4VP polymer towards Cr(III) ions in the presence of Cu(II), Mn(II) and Fe(III) ions, and slightly decreased the sorption capacity and stability of that polymer. The accuracy of procedures based on both polymeric sorbents was proved by analyzing the standard reference material of surface water SRM 1643e. The method using the Cr(III)-phen-ST polymer was applied for determining of Cr(III) ions in tap water and infusion of a green tea. Full article

A new copper sensitive all solid-state ion-selective electrode was prepared using multiwalled carbon nanotubes-ionic liquid (1-butyl-3-methylimidazolium hexafluorophosphate) nanocomposite as an additional membrane component. The effect of nanocomposite content in the membrane on the electrode parameters was investigated. The study compares, among others, detection limits, sensitivity, and the linearity ranges of calibration curves. Content 6 wt.% was considered optimal for obtaining an electrode with a Nernstian response of 29.8 mV/decade. An electrode with an optimal nanocomposite content in the membrane showed a lower limit of detection, a wider linear range and pH range, as well as better selectivity and potential stability compared to the unmodified electrode. It was successfully applied for copper determination in real water samples. Full article
