“…Hence, liver is a good indicator of marine environmental pollution. Researchers pointed out the importance of liver in processes of storing, redistributing, detoxifying, and transforming contaminants depending on age and sex (Burger and Gochfeld 2007 ; Havelková et al 2008 ; Kwaśniak and Falkowska 2012 ).…”

“…The negative correlation between OP and NP concentrations in muscles and the weight of cod (Table 6 ) was probably influenced by the lower fat content in cod compared with herring and flounder (Reindl et al 2013 ; Kwaśniak and Falkowska 2012 ). The observed liver/muscle concentration ratio for NP and OP, which in cod increased with weight (age), could have resulted from the length of exposure to xenobiotics.…”

The organic derivatives of phenol are classed as dangerous compounds, and their presence has been detected in surface water, bottom water, phytoplankton, zooplankton, and mussel as well as liver and muscle of fish from the Gulf of Gdańsk and in liver, muscle, and guano of gulls residing in the coastal zone of this basin. The greatest sources of bisphenol A (BPA), 4-tert-octylphenol (OP), and 4-nonylphenol (NP) were found to be the Vistula River and the water purification plant in Dębogórze. In living organisms, concentrations of BPA, OP, and NP ranged between the limit of quantification and several hundred ng g−1 dry weight (dw), and the highest concentrations were found for BPA. Prolonged alimentary exposure to BPA, OP, and NP in fish and birds was indicated by liver/muscle concentration ratios generally >1. The most influential factors on BPA and alkylphenol concentrations in the tissues of fishes and gulls were mainly diet and habitat. The study confirmed possible bioaccumulation in the food web. High BPA and NP concentrations in guano (≤2,700 and ≤300 ng g−1 dw, respectively) indicated the ability of birds to detoxify and signalled the reintroduction of these compounds to seawater. Herring, flounder, and cod from the Southern Baltic are a safe food source for human consumption because their BPA and alkylphenol contents are low.

“…Organic mercury usually dominates in the muscles of fish, and concentrations are usually significantly correlated with fish age and weight (Polak-Juszczak 2017 ). Methylmercury is the strongest of the neurotoxins, and it is mutagenic and causes disruptions in the circulatory system, the nervous system, reproductive parameters, and spawning (Hammerschmidt et al 2002 ; Kwaśniak and Falkowska 2012 ). Changes in biochemical processes in fish occur at concentrations of CH 3 Hg + from 0.5 to 1.2 μg g −1 w.w. in dorsal muscle (Dietz et al 2010 ).…”

The aim of this study was to determine the distribution of total mercury (THg), methylmercury (CH3Hg+), and inorganic mercury (Hginorg) in the tissues and organs of fish depending on species, tissue, and organ, and their bioaccumulation in tissues and biomagnification throughout the trophic web. The study included four species of fish (herring, sprat, cod, and eel) from the southern Baltic Sea. The concentrations of the different forms of mercury were determined in tissues and internal organs. Intra-specific differences in levels of THg, CH3Hg+, and Hginorg in the tissues and organs were determined. Muscle contained the highest proportions of THg and CH3Hg+ in comparison to that in the internal organs. Differences in concentrations of THg, CH3Hg+, and Hginorg in the tissues and organs of fish were related to their preferred prey. The bioaccumulation of CH3Hg+ in the tissues and organs of predatory fish at the highest trophic levels was greater than in the liver and digestive tract of fish species at lower trophic levels, in which Hginorg predominated. The high concentrations of CH3Hg+ in eel and cod and the low levels in herring and sprat were linked with their food and the transfer of this element among species. The results suggested that the type of food, feeding habits, and trophic position were important parameters that influenced the transfer and biomagnification of mercury in fish.

“…This indicates dominance of detoxification over accumulation processes. Several studies have shown that the liver has the ability to accumulate large amounts of pollutants from the external environment and plays an important role in their storage, redistribution, detoxification and transformation (Evans et al 1993;Wiener et al 2003;Kwaśniak, Falkowska 2012). No fungicides were found in the liver.…”

The aim of this study was to estimate the residue of chlorinated pesticides in the edible fish caught in the Gulf of Gdańsk and in the Vistula Lagoon. The highest mean concentrations of total DDT were found in the muscles of salmon (331.45 ng g -1 lw.) and sabre carp (306.29 ng g -1 lw.) caught in the Vistula Lagoon, and in the muscles of cod (309.88 ng g -1 lw.) and herring (304.86 ng g -1 lw.) from the Gulf of Gdańsk. Moreover, it was discovered that the following were present in the muscles of fish: DDT metabolites (pp'-DDE and pp'-DDD isomers) as well as hexachlorobenzene and its metabolites and endrin, dieldrin, α-endosulfan isomers and methoxychlor. Pesticides concentrations were higher in the livers of fish than in the muscles, which proves that the removal of toxins from the fish systems dominates over their accumulation. Because no concentration limits for pesticides have been defined, consumer safety assessment of fish caught in the Southern Baltic and in the Vistula Lagoon is not possible. The authors, having
