Effluent Exposure

The ever-increasing production and processing of textiles will lead to greater risks of releasing pollutants into the environment. Textile wastewater treatment plants (TWTPs) effluent are an important source of persistent toxic pollutants in receiving water bodies. The effects of specific pollutants on organisms are usually studied under laboratory conditions, and therefore, comprehensive results are not obtained regarding the chronic combined effects of pollutants under aquatic environmental conditions. Thus, this study aimed to determine the combined effects of TWTP effluents on the growth performance, oxidative stress, inflammatory response, and intestinal microbiota of adult zebrafish (Danio rerio). Exposure to TWTP effluents significantly inhibited growth, exacerbated the condition factor, and increased the mortality of adult zebrafish. Moreover, markedly decreases were observed in the activities of antioxidant enzymes, such as CAT, GSH, GSH-Px, MDA, SOD, and T-AOC, mostly in the intestine and muscle tissues of zebrafish after 1 and 4 months of exposure. In addition, the results demonstrated that TWTP effluent exposure affected the intestinal microbial community composition and decreased community diversity. Slight changes were found in the relative abundance of probiotic Lactobacillus, Akkermansia, and Lactococcus in zebrafish guts after chronic TWTP effluent exposure. The chronic toxic effects of slight increases in opportunistic pathogens, such as Mycoplasma, Stenotrophomonas, and Vibrio, deserve further attention. Our results reveal that TWTP effluent exposure poses potential health risks to aquatic organisms through growth inhibition, oxidative stress impairment of the intestine and muscles, and intestinal microbial community alterations.

Zebrafish are important animal models widely used in molecular biology research. To our best knowledge, no previous study on OT effects in zebrafishes� oxidative stress status was performed. Moreover, while the zebrafish are naturally producing isotocin, the investigation of its homologue OT effects may provide consistent evidence of the possible influence of oxytocin in isotocin naturally producing teleosteens. In this way, we aimed to analyse the influence of water exposure (e.g. branchial and tegmental exposure) on two different doses of OT (33.2 ng/mL and 66.4 ng/mL) on the adult zebrafish (n = 15) oxidative stress markers. Significant differences and correlations were found in the zebrafish exposed to a higher OT concentration, although lipid peroxidation tended to decrease as the OT concentration increased. Thus, it seems that oxytocin is cross-reacting and exerts clear effect on oxidative stress status main parameters in zebrafish.
