“…The case in Osaka Bay also showed that Zn was mostly concentrated in the Fe‐Mn oxide fraction. [ 52 ] The present study also observed a strong correlation between P‐Zn and P‐Fe at st.5 on weekdays, weekends, and during the monthly survey ( r = 0.703; p < 0.001), as shown in Figure 5 a. A correlation between P‐Zn and P‐Fe ( r = 0.430; p < 0.05) was also observed in the sediment of the lower Seyhan River.…”

Unlike other potentially toxic metals, zinc (Zn) is indispensable to life but also poses environmental risks to aquatic organisms. Aichi Prefecture has the Japan's fourth-highest discharges of Zn into water bodies. It is likely that the Zn fluxes in Aichi's water bodies originate from industrial wastewater. This study evaluates the spatial-temporal and diel variability of Zn on sunny days during weekdays and weekends in the Umeda River. The most downstream point is considered as the most polluted section according to the monthly survey [dissolved Zn (D-Zn): 0.0046-0.0719 mg L −1 , particulate Zn (P-Zn): 0.42-2.01 mg g −1 ] that varied between seasons (coefficient of variation: 95% for D-Zn; 53% for P-Zn). The total Zn (T-Zn) concentrations on weekdays (0.015-0.043 mg L −1 ) at the most downstream point exhibit much higher concentrations than those during the weekends (undetected-0.032 mg L −1 ). Given the dissolved phase of these Zn levels (77 ± 11%), the Zn are likely discharged by industrial facilities on weekdays. The T-Zn loading on weekdays (56 g km −2 d −1 ) is approximately three times higher than that on weekends. At least 67% of the T-Zn and 70% of the D-Zn fluxes from industrial point sources are potentially discharged on weekdays.

“…https://doi.org/10.1590/S1413-415220220230 Understanding the mobility of major oxides during the weathering processes has been proposed as an alternative to identify sediment formation zones (GOMES; ALMEIDA; SPERANDIO, 2018;SANG et al, 2018;SILVA et al, 2019;SOUSA et al, 2018). Additionally, sediment quality is often assessed by environmental geochemical indices based on average concentrations of local inorganic chemical compounds, the background values, compared to bottom levels as a tool for water resource management (BILLAH; KOKUSHI; UNO, 2019;MIZAEL et al, 2020). This method considers that variations of the average concentrations of fluvial sediments are associated with adverse effects on aquatic ecosystems, allowing to track down where such environmental stress sources are located (HERATH et al, 2018;KUSIN et al, 2019;SUNDARARAJAN et al, 2017).…”

Waste generated by mineral extraction is globally associated with environmental disturbances due to its deleterious effect on water resources. However, research focused on the influence of mine tailings resulting from the extraction of semi-precious stones on fluvial systems is still incipient in the environmental literature. From this perspective, this study quantified the average concentrations of major oxides present in the fine fractions of the sediment samples from the Várzea river, in the State of Rio Grande do Sul, southern Brazil, using wavelength dispersive X-ray fluorescence spectrometry. This region is acknowledged as the largest rock amethyst mining area in the world. Additionally, geochemical indices were established to characterize potential sources of production, maturity, degree of weathering, and sediment pollution. To evaluate the influence of mine tailings on the Várzea river sediments, the contents of Al2O3, Fe2O3, MnO, P2O5, CaO, SiO2, K2O, CuO, ZnO, and TiO2 major oxides present in sediment samples were determined and compared to the local background values; the values varied significantly (p < 0.05), classifying them as polluted and medium polluted. Also, the sediment samples with evident characteristics of extreme chemical weathering consist mainly of clay minerals and mafic igneous rocks, and similarities were found between sediment samples and tailings from the mineral extraction zone. The Principal Component Analysis and the cluster analysis also suggest the existence of three distinct mineral oxide groups, differentiating the zones leaving and upstream the mining zone from the other sampling points.

These metals were likely bound to the crystalline lattices of sediments and remain in inactive condition, indicating a low potential of bioavailability(Billah et al, 2019;Li, et al, 2001;Qiao et al, 2013). The distributions of geochemical species in Shidugawa and Furue Bays were slightly different from those in other areas.1.…”

Metal contamination is a crucial environmental issue because of its persistence and toxicity, which can have deleterious effects on aquatic ecosystems. Coastal sediments serve as reservoirs for metals. Aquaculture is an important human activity in coastal areas; however, the actual status of metal distribution in these areas has not been well characterized. We investigated the distribution and geochemical speciation of metals in the sediments of the Japanese aquaculture areas of Shidugawa and Furue Bays. Total metals were generally in the order Zn > Cu > Ni > Cd > Pb and occurred at high levels at the sites in the inner parts and near the fish cages in the sampling areas. Pearson’s correlations and principal component analysis results suggested that the metals in these aquaculture areas might originate from several sources, such as fish faeces, fish feeds, corrosion of antifouling material residues, and local anthropogenic activities, including fertilizers and manures. Furthermore, metals were mainly in silts and fine sediments, associated with residual speciation, followed by organic fractions, oxides, and high fractions of exchangeable Cd. These results provide important insights into the accumulation of metals in sediments for better managing marine aquaculture in Japan.
