Abstract (original English)

Freshwater pollution is a global issue that can impact aquatic organisms in multiple ways. One of the many detrimental consequences of freshwater pollution is the disruption of the intestinal microbiome in aquatic animals. This review addresses the impact of various chemical entities like pesticides, heavy metals, antibiotics, dyes, and microplastic. Gut microbiota serves as a crucial regulator of metabolic processes across all organisms. Since numerous metabolic pathways are coordinated by microbial communities, even minor disruptions can lead to consequences ranging from mild to severe. The widespread use of chemicals in modern life has made them a primary focus of current gut microbiota research. Zebrafish ( Danio rerio ) can serve as a model organism to investigate gut microbiome responses to exposure to hazardous contaminants. In this review we include research studying pesticides (methomyl, λ-cyhalothrin, cyproconazole, dieldrin, penthiopyrad, acetochlor, metamifop, imidacloprid, difenoconazole, imazalil, cypermethrin), heavy metals (lead, cadmium, arsenic, chromium, copper, and various nanoparticles), antibiotics (oxytetracycline, florfenicol, doxycycline, trimethoprim, erythromycin, streptomycin, tetracycline, sulfamethoxazole, and clarithromycin), and microplastics (polystyrene, polyethylene, polyester, polypropylene). This review study provides a description of microb
