“…Fish vulnerability to xenobiotics is not a constant and largely varies between individual organisms, but also within an organism in relation to its genetic makeup, life stage, development, gender, gonadal maturation, diseases, infestations, energy reserves, etc. Vulnerability also resides in the sensitivity and resilience of the system exposed to various hazards (Rudneva et al 2020;Turner et al 2003). Besides xenobiotics and pollutants, there is also many environmental stressors, which may affect fish communities: climate change, coastal or riverine development, erosion, alterations of hydrological systems, physicochemical changes of water and sediment, pathogen burden, toxic algae, invasive species, intra-and interspecific competitions, eutrophication, fishing, and aquaculture leading to the altered food web and habitat changes (Couillard et al 2008).…”

Wastewater treatment plants (WWTPs) continuously release a complex mixture of municipal, hospital, industrial, and runoff chemicals into the aquatic environment. These contaminants are both legacy contaminants and emerging-concern contaminants, affecting all tissues in a fish body, particularly the liver. The fish liver is the principal detoxifying organ and effects of consistent pollutant exposure can be evident on its cellular and tissue level. The objective of this paper is thus to provide an in-depth analysis of the WWTP contaminants’ impact on the fish liver structure, physiology, and metabolism. The paper also gives an overview of the fish liver biotransformation enzymes, antioxidant enzymes, and non-enzymatic antioxidants, their role in metabolizing xenobiotic compounds and coping with oxidative damage. Emphasis has been placed on highlighting the vulnerability of fish to xenobiotic compounds, and on biomonitoring of exposed fish, generally involving observation of biomarkers in caged or native fish. Furthermore, the paper systematically assesses the most common contaminants with the potential to affect fish liver tissue. Graphical Abstract
