“…In the European Union, a multinational programme to assess and hopefully control environmental toxins has been implemented by the EU‐funded BEEP (Biological Effects of Environmental Pollution) project as outlined by the ICES Baltic Committee (ICES ). This project led to the development of biomonitoring standards and procedures (Feist et al., ; Lehtonen et al., ), and provided data on levels of organic pollutants, and on biochemical, morphological, and genotoxic changes in Baltic fish (Baršienè et al., ; Dabrowska et al., ; Rybakovas, Baršienė, & Lang, ). Histopathological biomarkers of exposure to environmental toxins including hepatic and splenic melanomacrophages (without morphometry), hepatocellular cellular atypia including fibrillar inclusions, FCA, and hepatic adenomas were documented in Baltic demersal fish, the flounder Platichthys flesus (Dabrowska et al., ; Lang et al., ) and eelpout Zoarces viviparus (Fricke, Stentiford, Feist, & Lang, ), both of which are not top predatory species (Baršienè et al., , ; Bogovski, Lang, & Mellergaard, ; Rybakovas et al., ).…”

“…While overfishing is a major factor impacting the recovery of these stocks, environmental stressors are most likely involved (Eur‐lex.europa.eu; Schnell et al., ). As predatory fish cod biomagnify pollutants; accordingly cytotoxic and genotoxic changes have been reported from the Baltic cod in association to industrial contaminants (Baršienè et al., ; Hylland et al., ; Schnell et al., ). Due to the above biological characteristics cod has been listed as a sentinel/bioindicatory species of the Baltic (Davies & Vethaak, ; ICES ).…”

Selected biomarkers of health were examined in 50 post-spawning cod Gadus morhua collected in November 2015 from the southern Baltic. The biomarkers included condition factor (CF), macroscopic lesions, histopathology of spleen, liver and gonads, and morphometry of follicular atresia and hepatic and splenic melanomacrophage cells (MMC). All fish appeared in good body condition. One fish had a dermal ulcer, and in seven, macroscopic nematodes were noted within body cavity. Microscopic lesions in the liver included biliary myxozoanosis, microsporidial and necrocentric granulomas, parasitic hepatitis, multifocal necrosis, foci of cellular alterations, spongiosis, peliosis and cytoplasmic fibrillar inclusions. The spleen and gonads had microsporidial and/or necrocentric granulomas. Some of the biomarkers showed differences as compared to spawning cod collected in May from the same location in 2012, most importantly values an order of magnitude lower for splenic MMC in post-spawning fish. In post-spawning fish, there were statistically significant correlations between MMC, CF, follicular atresia, parasitic hepatitis and microsporidiosis. This is the first comparison of biomarkers of health in post-spawning and spawning Baltic cod. Future studies need to examine the relationships of biomarkers to levels of pollutants in the environment and in tissues of cod.

“…Although toxic effects of conventional munitions may be sublethal and difficult to detect, release of compounds from chemical munitions has been implicated in elevated genotoxicity and cytotoxicity observed in fish collected near munitions dumpsites in the Baltic Sea (Baršiene et al, 2014). Results were similar for fish collected near a chemical munitions site in the Adriatic Sea (Della Torre et al, 2010), although no munitions compounds were detected in fish tissues (Amato et al, 2006a).…”

Spread, Behavior, and Ecosystem Consequences of Conventional Munitions Compounds in Coastal Marine Waters

et al. 2018

Coastal marine environments are contaminated globally with a vast quantity of unexploded ordnance and munitions from intentional disposal. These munitions contain organic explosive compounds as well as a variety of metals, and represent point sources of chemical pollution to marine waters. Most underwater munitions originate from World Wars at the beginning of the twentieth century, and metal munitions housings have been impacted by extensive corrosion over the course of the following decades. As a result, the risk of munitions-related contaminant release to the water column is increasing. The behavior of munitions compounds is well-characterized in terrestrial systems and groundwater, but is only poorly understood in marine systems. Organic explosive compounds, primarily nitroaromatics and nitramines, can be degraded or transformed by a variety of biotic and abiotic mechanisms. These reaction products exhibit a range in biogeochemical characteristics such as sorption by particles and sediments, and variable environmental behavior as a result. The reaction products often exhibit increased toxicity to biological receptors and geochemical controls like sorption can limit this exposure. Environmental samples typically show low concentrations of munitions compounds in water and sediments (on the order of ng/L and µg/kg, respectively), and ecological risk appears generally low. Nonetheless, recent work demonstrates the possibility of sub-lethal genetic and metabolic effects. This review evaluates the state of knowledge on the occurrence, fate, and effect of munition-related chemical contaminants in the marine environment. There remain a number of knowledge gaps that limit our understanding of munitions-related contaminant spread and effect, and the need for additional work is made all the more urgent by increasing risk of release to the environment.

“…The number of MN (‰) in this area without strong frequencies (connected to the dumped munition) ranged from 0.42 to 1.65‰. The measurement of micronuclei in herring blood revealed the significant influence of CW on the aberration in fish erythrocytes, which has also been presented by [34]. The highest values of MN (‰) were observed in the simple specimen taken from the dumping site in the Polish Exclusive Economic Zone (30.0‰).…”

A micronucleus test is a common test used as a biological indicator reflecting environmental genotoxicity caused by some of the hazardous substances' presence, and due to this it is recommended as one of the indicators for marine environmental status assessment. To determine the status of the environment, herring blood samples were collected in 2014-2017 in the southern Baltic Sea area at seven fishing grounds. The conducted analysis revealed that there is no significant correlation between the number of micronuclei in erythrocytes and sampling locations each year. This could be a result of a similar chemical status of the assessed areas as well as similar physico-chemical characteristics, but also the individual condition of the examined fish has to be taken into account as well as the their size parameters (length and weight). Statistical analysis showed statistically significant differences between the results over the years of research. The highest median values in all locations occurred in 2017, in which they were in the range of 0.57-1.37, probably as a result of longer lengths. The threshold value was exceeded in 2016 and 2017 in all locations, indicating inadequate status of the marine environment.
