“…Furthermore, non-traditional isotope systems, notably the zinc isotopes, have been successfully applied as tracers of anthropogenic emissions and lowtemperature biogeochemical processes in large river basins (Chen et al, 2009b;Desaulty and Petelet-Giraud, 2020;Petit et al, 2015;Zimmermann et al, 2020). Zn isotope compositions (expressed as δ 66/64 ZnJMC notation) are used as source identification tools (Araújo et al, 2017a;Li et al, 2019;Tonhá et al, 2020;Xia et al, 2020), which can distinguish between lithogenic materials derived from weathering processes (+0.28 ± 0.05 ‰) (Chen et al, 2013) and anthropogenic materials, such as road dust (+0.08 to +0.17 ‰) and tire-wear (+0.00 to +0.22 ‰) (Dong et al, 2017;Souto-Oliveira et al, 2019).…”

The Paraiba do Sul (PSR) and Guandu Rivers (GR) water diversion system (120 km long) is located in the main industrial pole of Brazil and supplies drinking water for 9.4 million people in the metropolitan region of Rio de Janeiro. This study aims to discern the trace metals dynamics in this complex aquatic system. We used a combined approach of geochemical tools such as geochemical partitioning, Zn isotopes signatures, and multivariate statistics. Zinc and Pb concentrations in Suspended Particulate Matter (SPM) and sediments were considerably higher in some sites. The sediment partition of As, Cr, and Cu revealed the residual fraction (F4) as the main fraction for these elements, indicating low mobility. Zinc and Pb were mostly associated with the exchangeable/carbonate (F1) and the reducible (F2) fractions, respectively, implying a higher susceptibility of these elements to being released from sediments. Zinc isotopic compositions of sediments and SPM fell in a binary mixing source process between lithogenic (δ66/64ZnJMC ≈ + 0.30‰) and anthropogenic (δ66/64ZnJMC ≈ + 0.15‰) end members. The lighter δ66/64ZnJMC values accompanied by high Zn concentrations in exchangeable/carbonate fraction (ZnF1) enable the tracking of Zn anthropogenic sources in the studied rivers. Overall, the results indicated that Hg, Pb, and Zn had a dominant anthropogenic origin linked to the industrial activities, while As, Cr, and Cu were mainly associated with lithogenic sources.

“…In drinking water, the maximum allowable limit for nickel is 0.1 ppm [8]. Zinc (Zn) is used in many types of industry, such as metal production, galvanization, food preservation, agri-food and biological engineering, pharmaceuticals, electronics, mining and metallurgy, with major contributions coming from electroplating and mining effluents [9,10]. Zinc is not considered highly toxic but its presence in drinking water if exceeding 15 mg/L is reported to cause nausea, vomiting and diarrhea [11].…”

Heavy metal contamination in water is a major health concern, directly related to rapid growth in industrialization, urbanization, and modernization in agriculture. Keeping this in view, the present study has attempted to develop models for the process optimization of nanofiltration (NF) membrane and electrocoagulation (EC) processes for the removal of copper, nickel, and zinc from an aqueous solution, employing the response surface methodology (RSM). The variable factors were feed concentration, temperature, pH, and pressure for the NF membrane process; and time, solution pH, feed concentration, and current for the EC process, respectively. The central composite design (CCD), the most commonly used fractional factorial design, was employed to plan the experiments. RSM models were statistically analyzed using analysis of variance (ANOVA). For the NF membrane, the rejection of Zn, Ni, and Cu was observed as 98.64%, 90.54%, and 99.79% respectively; while the removal of these through the EC process was observed as 99.81%, 99.99%, and 99.98%, respectively. The above findings and a comparison with the conventional precipitation and adsorption processes apparently indicate an advantage in employing the NF and EC processes. Further, between the two, the EC process emerged as more efficient than the NF process for the removal of the studied metals.

“…The precipitation of industrial PM through rain, production of industrial wastewater, or electroplating sludge disposal can introduce toxic electroplating products into soil and water bodies [ [21] , [22] , [23] ]. Intensified human activities in coastal regions [ 24 , 25 ] lead to progressive degradation of coastal and marine ecosystems [ 26 ] and can facilitate the transfer of toxic metals and persistent organic pollutants through food chains to seafood, fish, and eventually to humans [ 27 , 28 ]. The regulation of the negative impact of pollutant emissions on the aquatic environment requires the consideration of standards for different types of pollutants.…”
