“…Moreover, comparison of data obtained prior and subsequent to the installation of a new wastewater treatment technology [13][14][15][16][17][18] or of samples taken at different steps within the treatment process [19,20] was shown to be a valuable strategy to evaluate the efficiency of this new technology. Especially in situ exposure (active monitoring) of caged fish has often been applied in this context [21,22]. Compared to the passive approach, i.e.…”

“…knowledge about the exposure period and standardization regarding the age, size and reproductive stage of the exposed individuals. Furthermore, adaptive responses that may result in a desensitization of the organisms' physiological responses can be excluded in active monitoring [21,23]. Thus, caging of fish can help to control different parameters that might affect the subsequently analyzed biomarkers.…”

Background: In situ exposure of rainbow trout up-and downstream of differently equipped wastewater treatment plants (WWTPs) and subsequent analyses of micronuclei frequencies and hepatic EROD activities were used to evaluate the impact of the effluents on fish health. Two of the facilities (WWTPs A and B) were conventional treatment plants. WWTP C has been equipped with a powdered activated carbon stage. Here, analyses were conducted prior and subsequent to this upgrade. Results:Differences did not only occur when comparing conventional (WWTPs A, B and C prior to the upgrade) and advanced treatment (WWTP C after the upgrade), but also between the conventionally equipped WWTPs. There was no indication for genotoxic effects or pollution-related EROD induction in fish exposed at WWTP A. In contrast, trout exposed at WWTP B expressed strong reactions. However, here, adverse reactions were also observed in fish kept upstream. Similar observations were made for EROD activities in fish exposed at WWTP C prior to the upgrade, whereas genotoxic effects could only be seen in trout kept downstream of this effluent. Upgrading of WWTP C resulted in a significant reduction of both genotoxic effects and EROD levels. Conclusions:The results show financial investments in advanced wastewater treatment to be beneficial for aquatic ecosystems, especially when conventional technologies do not sufficiently remove pollutants. Yet, negative impacts of effluents on aquatic organisms can, under certain conditions, also be avoided by conventional treatment. Therefore, we recommend deciding on the necessity and the type of WWTP upgrading on a case-by-case basis. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

“…In urban areas, aquatic ecosystems are more susceptible to degradation, and many vertebrates and invertebrates have been used to monitor environmental quality. Changes in functional enzymes (Bonnail et al 2016;Vieira et al 2017;Sadauskas-Henrique et al 2017), effects of cytogenotoxicity (Prado, et al 2014, de Almeida Duarte et al 2016, mutagenicity (Araújo al. 2014;Weldetinsae et al 2017), and hematological, immunological, and histopathological changes (da Cruz et al, 2015;Corrêa et al 2017;Thummabancha et al 2016;Hedayati and Darabitabar 2017) all represent well-documented biomarkers used in environmental monitoring.…”

The present study evaluated the water quality of a polluted pond through the analysis of in vitro mucociliary transport, hematological parameters, and biomarkers of cyto-genotoxicity in the Nile tilapia (Oreochromis niloticus). Blood and mucus samples were collected from ten specimens from the polluted pond and from ten specimens from a control area. The fish were anesthetized with 3% benzocaine, mucus was collected directly from the gills, and blood was drawn from the caudal artery. Blood smears were stained using the May-Grünwald Giemsa process for the differential leukocyte counts and to determine the frequency of leukocytes, thrombocytes, erythroblasts, micronuclei, and nuclear abnormalities. The results revealed low transportability in vitro, a high percentage of monocytes and eosinophils, and increased frequency of leukocytes and nuclear abnormalities in fish from the polluted pond. However, the frequency of thrombocytes and erythroblasts and the percentage of lymphocytes and neutrophils were significantly lower. It is possible to conclude that changes in fish are due to poor water quality and that these non-destructive biomarkers can be used for the biomonitoring of aquatic environments vulnerable to contamination.

“…Anthropogenic activities have been caused the contamination of aquatic ecosystems and studies that evaluate this contamination and their toxic effects to the environment are increasingly required (Vieira et al, 2017). Agriculture, is one of this activities that results in several negative impacts to the environment such as soil degradation, deforestation and the soil and water contamination due to the use of the fertilizers and pesticides (Ren et al, 2018).…”

Agriculture residues and domestic effluents are contaminants that reach aquatic ecosystems leading to toxic effects to environment and human health. These contaminants impacting mainly developing countries, due to precarious treatment of effluents and lack of legislation in the use of pesticides. Perequê River (South of Brazil) is impacted by pesticides (mainly glyphosate) and domestic effluents. The aims of this study were to analyze the concentration of glyphosate in water and sediments of Perequê River; and to evaluate the sublethal effects of the river contamination in Astyanax altiparanae using biomarkers. A sampling of water, sediment and fish were carried out in Perequê River (November/2016). The samples were collected in two sites, site 1 (S1) that is located on agriculture area and water catchment point; and site 2 (S2) located on the area with a domestic effluents influence. Water and sediment samples were used to glyphosate quantification. Fish were collected and tissues (brain, muscle, liver) were used to biochemical and genetic biomarkers. Glyphosate were quantified in S1, which is impacted by agriculture. Alterations in the liver biomarkers were not observed between the sites. However, the decrease in the AChE activity was observed in the S2, showing that the mixture of contaminants (urban and agriculture contaminants) can lead to anticholinesterasic effects. The sublethal effects observed can be a threat of environmental and human health.
