“…Fish is considered as a good indicator for the long-term research about TEs contamination in the aquatic habitats (9) and many studies have been conducted on the TEs concentrations in different fish species (10,11). The Caspian Sea is the largest lake in the world (12,13). It is under pressure from environmental threats such as discharge of industrial and agricultural effluents and growing urbanization in most riparian countries of the Caspian Sea (14,15).…”

Background: There is little information about the trace elements (TEs) concentrations in the muscle tissue of Caspian kutum (Rutilus kutum) in the South Caspian Sea. Methods: A total of 51 R. kutum specimens were caught at five fishing stations (Gorgan, Sari, Kiashahr, Anzali, and Astara) in the South Caspian Sea from September 2018 to January 2019. The inductively coupled plasma-optical emission spectrometry (ICP-OES) was employed to measure the TEs concentrations in the fish muscles. Results: The maximum concentrations of Al (7.2 ppm), Pb (0.07 ppm), and Ni (0.02) were reported in Astara, and the highest concentrations of As (0.2 ppm), Cu (0.49 ppm), Cr (0.12 ppm), and Zn (1.56 ppm) were reported in Sari and Gorgan. The TEs concentrations measured in the fish muscles (except Mg, Zn, As, Al, Na, and S) had no significant differences among the sampling areas. The TEs concentrations were higher in the eastern areas (Sari and Gorgan) than in the western areas (Astara, Anzali, and Kiashahr) excluding As and Al. The concentrations of Pb, Zn, Mn, Cu, Sn, Sb, Al, Cr, and Cd in muscles of R. kutum were found to be significantly lower (P<0.05) than the maximum permitted levels according to the WHO/FAO standards, while As concentrations were comparable to these standards. Conclusion: The TEs concentrations in different fishing stations of Kiashahr, Anzali, and Astara, located in the southwestern areas were respectively compared with those obtained from Sari and Gorgan, located in the middle and southeastern shore of the Caspian Sea. According to the results, the TEs concentrations obtained from the fish muscles cannot pose a threat to human health.

Pesticides can induce changes in behavior and reduce the survival chance of aquatic organisms. In this study, the toxic effects of glyphosate suspension (Glyphosate Aria 41% SL, Tehran Iran) on behavior and tissues of common carp (Cyprinus carpio) were assessed. For this purpose, a 96 h LC50 of glyphosate suspension (68.788 mL·L−1) was used in the toxicity test. All individuals were divided into control and treatment groups with four replicates. Exposure operations were performed under two conditions: increasing concentration of suspension from 0 to 68.788 mL·L−1; then, decreasing to the first level. The swimming pattern was recorded by digital cameras during the test and tissue samples were collected at the end of the test. There were significant differences between the swimming pattern of treated individuals and control ones during both steps. The sublethal concentration of glyphosate led to hypertrophy, hyperplasia and hyperemia in the gill of fish. However, changes were obvious only after sampling. The exposed fish also displayed clinical signs such as darkening of the skin and increasing movement of the operculum. Moreover, glyphosate suspension affected swimming patterns of fish suggest that the swimming behavior test can indicate the potential toxicity of environmental pollutants and be used as a noninvasive, useful method for managing environmental changes and assessing fish health conditions by video monitoring.

“…In natural lakes and reservoirs, those effects can be serious, since glyphosate can affect the structure of primary producers' communities (Lozano et al, 2018; Hernández-Garcia and Martínez-Jerónimo, 2020) as well as consumers' assemblages (Rico-Martínez et al, 2012;Vajargah et al, 2018), besides being a potential hazard to human health. Evidence like this highlights the threats posed by the presence of glyphosate in multiple-use reservoirs.…”

Glyphosate is a popular herbicide used worldwide, and several studies consider it to be an environmental hazard affecting human health. The present study aimed to detect glyphosate in six different reservoirs of Paraíba do Sul and Guandu River Basins in Southeast Brazil, used for multiple purposes, including fishery activities and domestic water supply. Ion chromatography was used to analyze the water samples, as it is a fast and environmentally friendly technique to detect glyphosate. Our results revealed that, despite differences related to trophic state, season of the year or distance to urban areas, glyphosate was detected in all reservoirs and in three of them with concentrations above the limit imposed by Brazilian legislation. Among the environmental variables studied, turbidity presented the highest correlation with glyphosate concentrations. The effect of rainfall increasing turbidity in the rivers reinforces the importance of draining waters from surrounding areas that transport glyphosate into the aquatic ecosystems. The detection of the herbicide in the various systems confirms the wide use of this compound in the drainage basins of the studied reservoirs and highlights the importance of water monitoring. Further, the results reveal how urgent and important it is to explore through laboratory experiments the pathways of degradation of this herbicide in tropical and subtropical aquatic environments together with its effects on flora and fauna.
