“…Sediments in the oceans, riverbeds, and natural and constructed wetlands often act as a major sink for nutrients and contaminants, such as carbon (Mitsch et al, 2013; Wang et al, 2022), pesticides (Arias et al, 2011; Kronvang et al, 2003), pharmaceuticals (Peck et al, 2004), microplastics (Kabir et al, 2022; Kanhai et al, 2019), radioactive materials (Kaplan et al, 2017), and trace metals including copper (Cu) and zinc (Zn; Li et al, 2007; Ye et al, 2003; Zamani‐Ahmadmahmoodi et al, 2020; Zhang et al, 2021). With the aid of substrates and soil in the sediments, macrophytes, microbial activities, and hydrological conditions, constructed wetlands help in filtering the overlying water from various contaminants (Sheoran & Sheoran, 2006).…”

Sediments in aquatic systems often act as a major sink for contaminants. Diffusive gradient in thin films (DGTs) and in situ equilibrium dialysis samplers (peepers) are two major in situ porewater sampling devices that overcome the problems associated with conventional porewater sampling methods. In this study, DGTs and peepers were used to study the spatial and seasonal effects (cool months: October‐February, warm months: May‐September) on metal bioavailability in the H‐02 constructed wetland, and the sink vs. source role of the sediments by calculating the metal resupply capacity (R). Data showed similar seasonal trends in metal concentrations using both passive samplers, peepers and DGTs. Pooled Cu and Zn concentrations measured using DGTs were lower in warm months (1.67 ± 1.50 and 2.62 ± 0.68 μg.L‐1, respectively, p < 0.001) vs. (2.12 ± 0.65 and 5.58 ± 1.33 μg.L‐1, respectively, p < 0.001) in cool months (mean ± 95% Confidence Intervals). Sulfate (SO42‐) concentrations were significantly (p = 0.0139) lower in warm months (averaged at 0.22 ± 0.05 mg.L‐1) compared to (0.16 ± 0.05 mg.L‐1) in cool months. The increase in SO42‐ concentration is an indicator of the lower activity of sulfate reducing bacteria (SRB) which need SO42‐ during the anaerobic respiration, in which SO42‐ is reduced to sulfide (S2‐) which forms insoluble salts with Cu and Zn, which could partially explain higher bioavailability of these metals in the cool season. Metal resupply capacity of the sediments was mostly < 0.2 for Cu and Zn. Taken together, the H0‐2 wetland sediments mostly acted as a sink to both Cu and Zn over the course of this study.

“…Such waste affects the water bodies and soils in the area (Ramírez and Lacasaña 2001 ). Mining activities can result in the release of PTEs to the environment, which can have harmful effects on the ecosystem (Nanos et al 2015 ; Odumo et al 2018 ; Zamani-Ahmadmahmoodi et al 2020 ; Mirzaei et al 2014 ; Rodríguez Martín et al 2014 ). Such mining discharges reach surface water bodies and accumulate in sediments (Odumo et al 2014 ; Zamani-Ahmadmahmoodi et al 2020 ).…”

Such mining discharges reach surface water bodies and accumulate in sediments (Odumo et al 2014 ; Zamani-Ahmadmahmoodi et al 2020 ). In our case, this situation affects water resources like River Chaguana, River Puyango, River Siete, River Gala and River Chico, and generally the water system in the area (Appleton et al 2001 ) that, in turn, affects the El Oro Province region (Vilela-Pincay et al 2020 ).…”

Shrimp production is an important industry for many countries and shrimp consumption is increasing worldwide. Shrimps are a highly nutritional food, but can pose a risk for human health if subject to high levels of environmental contaminants. This work studies the presence of As, Cd, Co, Cr, Cu, Hg, Ni, Pb and Zn in shrimps from Ecuador and compares them to such contents noted in other shrimp-production areas in the world to evaluate the possible risks associated with these elements for consumer health, and to relate them to potentially toxic element (PTE) contents in water, sediments and diets, and also to animal biometric parameters. The PTE levels (mg kg−1 DM) obtained are as follows: in the head—As (3.52–6.11), Cd (0.02–0.10), Co (0.14–0.49) Cr (0.23–4.89), Cu (99.9––233.0), Ni (0.52–1.86), Pb (0.24–1.09), Zn (51.8–100.5) and Hg (μg kg−1 DM) (10.00–66.81); in the tail—(0.91–3.21), Cd (0.01–0.02), Co (0.01–0.43) Cr (0.01–6.52), Cu (20.0–72.44), Ni (0.15–2.03), Pb (0.01–0.69), Zn (31.2–66.1) and Hg (μg kg−1 DM) (10.00–67.18). The concentration of all the PTEs is generally lower than the limits set for seafood by European regulations, except for As in the cephalothorax (4.63 mg kg−1). Different behaviours for PTE accumulation in shrimps were found, which preferentially tend to accumulate in the cephalothorax, except for Hg (40.13 μg kg−1 DM), which accumulates in muscle (body) and is associated with contents of proteins, lipids and total shrimp weight. Nonetheless, the target hazard quotient (THQ) values for PTEs indicate that the consumption of shrimp muscles from Ecuador does not pose a human health risk because the values of these indices are below 1 in all cases.
