“…In the present work, parallel studies were carried out on the toxic effect and the induction of oxidative stress caused by the presence of copper (Cu) and arsenic (As) and the NPs of these elements (Cu-NPs and As-NPs) in seabass larvae, allowing for a good comparison between two different pollutants and two chemical forms. In order to avoid possible alterations that could cause stress in individuals, a static model was used, evaluating a wide range of environmentally relevant concentrations in accordance with previous studies assessing Cu and As concentrations in different aquatic ecosystems [ 27 , 28 , 29 , 30 ]. As a whole, the two chemical forms of Cu exhibited a higher bioaccumulation and toxicity as compared to those of As.…”

“…According to previous studies in the literature analysing trace element concentrations in different ecosystems, the ranges of As and Cu in waters varied according to the quality of the ecosystems, establishing the following examples of intervals: from 0.5–0.8 μg/L in Algeciras Bay (Spain) [ 27 ] to <LOD to 43 mg/L in Kuwait Bay [ 28 ] for As and from 0.18–0.66 mg/L in Pasajes Harbour (Spain) [ 29 ] to 36.97–230.94 mg/L in Kakinada Bay (India) [ 30 ] for Cu. On the other hand, the Gulf of Cádiz in Spain has been historically impacted by acid mine drainage and the discharge of rivers such as the Guadiana and Guadalquivir.…”

The aim of this work was to compare the potential induction of oxidative stress and the antioxidant enzymatic response after a short-term waterborne exposure to copper (Cu) and arsenic (As) with that of the nanoparticles (NPs) of these elements (Cu-NPs and As-NPs) in fish larvae of the species Dicentrarchus labrax. Larvae were grouped in several tanks and exposed to different concentrations of contaminants (0 to 10 mg/L) for 24 or 96 h under laboratory conditions. Copper and arsenic concentrations were analysed in larval tissues using ICP-MS. A set of oxidative stress biomarkers, including the levels of hydroperoxides (HPs), and superoxide dismutase (SOD) and catalase (CAT) activities were assessed. The trace element concentrations (mg/kg d.w.) in larvae ranged as follows: 3.28–6.67 (Cu at 24 h) and 2.76–3.42 (Cu at 96 h); 3.03–8.31 (Cu-NPs at 24 h) and 2.50–4.86 (Cu-NPs at 96 h); 1.92–3.45 (As at 24 h) and 2.22–4.71 (As at 96 h); and 2.19–8.56 (As-NPs at 24 h) and 1.75–9.90 (As-NPs at 96 h). In Cu tests, the oxidative damage (ROOH levels) was induced from 0.1 mg/L at both exposure times, while for Cu-NPs, this damage was not observed until 1 mg/L, which was paralleled by concomitant increases in SOD activity. The CAT activity was also increased but at lower metal concentrations (0.01 mg/L and 0.1 mg/L for both chemical forms). No oxidative damage was observed for As or As-NPs after 24 h, but it was observed for As after 96 h of treatment with 0.01 mg/L. A decrease in SOD activity was observed for As after 24 h, but it turned out to be increased after 96 h. However, As-NPs did not alter SOD activity. The CAT activity was stimulated only at 96 h by As and at 24 h by As-NPs. Therefore, the two chemical forms of Cu exhibited a higher bioaccumulation and toxicity potential as compared to those of As. Importantly, the association of both Cu and As in NPs reduced the respective trace metal bioaccumulation, resulting also in a reduction in the toxic effects (mortality and biochemical). Furthermore, the assessment of oxidative stress-related biomarkers in seabass larvae appears to be a useful tool for biomonitoring environmental-occurring trace elements.

“…Ingestion, inhalation, and dermal absorption are the three main ways that humans may be exposed to heavy metals. When it comes to the health of individuals who participate in water-related activities, skin exposure to contaminated saltwater is more dangerous than ingesting or inhalation [53][54][55]. In the current study, carcinogenic and noncarcinogenic risk factors were used to evaluate the health hazards associated with heavy metal exposure for men, women, and children [56; 8].…”

Trace metals (Li, B, Na, Mg, Al, K, Ca, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Se, Sr, Ag, Cd, In, Ba, Hg, Pb, Bi) in surface sediments of the Nile Delta coastal area between Western Harbor and Bardaweel Lagoon were evaluated. The ecological risk assessment was evaluated by Contamination degree (Cd), Geoaccumulation Factor (Igeo), Enrichment Factor (EF), Contamination Factor (CF), Hazard Quotient (HQ) and Pollution Load Index (PLI). The EF values are in the sequence: Cr > Pb > Ni > Zn > Cu > Mn. The studied locations were unpolluted with Cr, Cu, Mn, Ni, Pb, and Zn (Igeo ≤0) and the Cd (> 1.5). Significant correlations were reported between the concentrations of Mn, Fe, Cr, Co and Ni suggesting similar sources. The HQ indicate low values for children and 3–4 > adult values. Using principal component analysis (PCA), the sources of heavy metals were categorized.

“…Based on the analysis results, the concentration of Pb in the waters at each station has exceeded the threshold, and Cu was not detected. Avvari et al (2022) stated that heavy metals in the water could disperse rapidly from their source because seawater is temporary and is affected by currents, tides, and other physical movements. Sampling in this study was carried out during low tide conditions.…”

Heavy metal pollution from anthropogenic activities can harm aquatic ecosystems. This study aims to determine the concentration of heavy metals (Pb and Cu) in waters, sediments, and mud crabs (Scylla serrata), and to analyze the relationship between environmental parameters and S. serrata consumed by humans. Samples were taken in the mangrove ecosystem around the Tanjung Api-Api port area in South Sumatra, Indonesia. Pb and Cu analysis used the Atomic Absorption Spectrophotometer (AAS). Pb and Cu linkages in waters, sediments, and S. serrata analyzed by SigmaPlot V12.5 and Principal Component Analysis (PCA) analyzed by XLSTAT 2022. The limit consumption of S. serrata was calculated using MWI (Maximum Weekly Intake) and MIT (Maximum Intake Tolerance). Based on the results, the heavy metal Pb in water was 0.1055 – 0.1322 mg.L-1, and Cu was not detected. Furthermore, Pb in sediments ranged from 7.0104 - 11.8186 mg.kg-1, Cu 3.7127 - 4.5347 mg.kg-1, and Pb in S. serrata ranged from 0.0001 - 0.0021 mg.kg-1, and Cu ranged from 0.03 – 0.0791 mg.kg-1. The concentration of heavy metals in water, sediment, and S. serrata had not exceeded the specified quality standard, except for Pb in water. The principal component analysis obtained F1 (44.35%), F2 (27.53%) and F3 (17.83%) groups. Based on MWI and MIT value, it showed high quality which concluded S. serrata was still safe for human consumption.
