“…Regarding the CAT, it exhibited a clear trend in the organisms exposed to 15 °C, increasing significantly in the organisms exposed to Cu. Similar results were observed in other marine bivalve species, such as R. decussatus [ 62 ], M. galloprovincialis and Perna perna [ 70 ]. Moreover, organisms exposed to 20 °C exhibited a slight increase in the CAT when exposed to Cu and oxyfluorfen, with this increase being significant at 1.88 mg L −1 and 9.49 mg L −1 of oxyfluorfen.…”

Currently, there is increased chemical pollution, and climate change is a major concern to scientific, political and social communities globally. Marine systems are very susceptible to changes, and considering the ecological and economic roles of bivalve species, like Cerastoderma edule, studies evaluating the effects of both stressors are of great importance. This study intends to (a) determine the toxicity of copper (Cu) and oxyfluorfen at the lethal level, considering the temperature; (b) assess the changes in the antioxidant defence enzymes as a consequence of the simultaneous exposure to chemical and warming pressures; and (c) determine if lipid peroxidation (LPO) and neurotoxic effects occur after the exposure to chemical and temperature stressors. C. edule was exposed to Cu and oxyfluorfen at different temperatures (15 °C, 20 °C and 25 °C) for 96 h. The ecotoxicological results reveal a higher tolerance of C. edule to oxyfluorfen than to Cu, regardless of the temperature. The antioxidant defence system revealed efficiency in fighting the chemicals’ action, with no significant changes in the thiobarbituric reactive species (TBARS) levels to 15 °C and 20 °C. However, a significant inhibition of acetylcholinesterase (AChE) was observed on the organisms exposed to oxyfluorfen at 20 °C, as well as a decreasing trend on the ones exposed to Cu at this temperature. Moreover, the catalase (CAT) showed a significant increase in the organisms exposed to the two highest concentrations of Cu at 15 °C and in the ones exposed to the highest concentration of oxyfluorfen at 20 °C. Looking at the temperature as a single stressor, the organisms exposed to 25 °C revealed a significant increase in the TBARS level, suggesting potential LPO and explaining the great mortality at this condition.

“…R.O. Bua et al 23) and S. Kourdali et al 24) in their studies on the Adriatic Sea note the absence of detection of benzofluoranthene, dibenzoanthracene, benzoperylene, and indenopyrene, while seven of the sixteen targeted PAHs were detected in all muscle tissue samples. Benzoanthracene and chrysene were detected in more than 30% of the samples, while benzofluoranthene and benzpyrene, recognised by the International Agency for Research on Cancer as the most carcinogenic PAH, were detected in only 3 samples out of 8 analysed, and their concentrations were close to the limit of quantitative determinations (0.2 µg/kg).…”

The aim of the work was to measure the concentration of organochlorine insecticides, heavy metals, and hydrocarbons from the oil series in samples of marine fish from diverse oceans in the region. To achieve the goal, the methods of high-performance liquid chromatography and atomic absorption spectrometry, as well as the statistical method, were used. A total of 250 marine fish samples collected from the Caspian, Black, Baltic, Azov, and Okhotsk seas were analysed. The results of the study showed significant concentrations of organochlorine pesticides, including isomers of hexachlorocyclohexane (HCH), in fish living in the Caspian, Black and Baltic Seas. Specifically, the Caspian Sea is found to have the highest HCH content of 0.2123 mg/kg, while the Black Sea and Baltic Sea show 0.2031 mg/kg and 0.0187 mg/kg respectively. Heavy metals such as lead (Pb), cadmium (Cd), and chromium (Cr) have also been found in fish samples. A comparative analysis of the content of pollutants in marine fish of the Eurasian region allows to draw the following conclusions: in fish living in the Caspian, Black and Baltic seas, there is a high concentration of organochlorine pesticides, heavy metals and petroleum hydrocarbons. This indicates significant pollution of the marine ecosystem by these substances. These studies highlight the need to control pollution of marine fish with pollutants and monitor the state of marine ecosystems to ensure the safety of fish consumption and public health.
