Fang et al 30) it was found that the concentration of the total a, ß and y isomers of HCH in fish muscle tissue samples collected during the 2nd expedition exceeded the maximum permissible level. The level of excess in the roach was 9.2 times the level of the maximum allowable concentration.…”

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.

“…In this frame, the utility of using different shellfish as indicator species in biomonitoring studies has been investigated by analysing mussels, clams, oysters and scallops collected at the North‐East coast of the Mediterranean Sea and from Pacific and Atlantic Ocean. These filter‐feeding organism has long been exploited for their ability to accumulate xenobiotics from the surrounding environment, thus to reflect the xenobiotics presence of their proximity environment 15–18 . The different distribution of PFAS between water and sediments observed especially for branched isomers and long‐chain molecules highlighted in a number of studies in marine settings 20,21 may also be reflected into biota.…”

Per-and polyfluoroalkyl substances (PFAS) are a numerous class of chemical compounds characterized by a C-F backbone of variable length with either a sulfonic acid group (PFSA) or a carboxylic acid (PFCA), produced for more than 70 years at industrial level. 1 PFOS and PFOA are the predominantly cited molecules of this class. Currently, these compounds are debated both at scientific and political levels due to the risks associated to exposure to legacy (PFOA, PFOS, etc.) and to emerging perfluorinated compounds (HFPO-DA or GenX, ADONA, C 6 O 4 ), introduced after the banning in the production/ import/use of PFOA and PFOS. 2,3 Studies on the bioaccumulation factor (BAF) of PFAS-that is, the degree of accumulation of a contaminant in an organism relative to its environment-correlated the length of the carbon chain (C6 > PFSA and C8 > PFCA) to higher BAF potential. On this base, the class of emerging PFAS, characterized by a shorter C-F backbone, had been considered less hazardous. Recent findings, however, confirm a lower accumulation potential in biota for short chain PFAS but similar toxicological effects as long chain counterparts. 4,5 Moreover, analyses on surface and ground waters at PFAS production plants discovered the incidence of important quantities of PFOA and PFOS branched isomers. The amounts were closely associated with the chemical reaction adopted for the production (electrochemical fluorination vs. telomerization) at the site, which consist of 22-29% of the total amount produced. 6 In the environment, branched isomers have been reported to concentrate in higher amount in soil and sediments, with less tendency to leaching, 6,7 while at biological level, they displayed different partitioning, bioaccumulation, metabolism and toxicity in living organism. 8,9 At present, studies showed as

“…The properties of the constituents influence how the spilled oil behaves and determines the fate and effects of the spill in the environment [1]. Among the components of crude oil, polycyclic aromatic hydrocarbons (PAHs) are a class of organic contaminants that contain two or more fused benzene rings; they are considered important after oil spill accidents because they are toxic, mutagenic, carcinogenic, and relatively persistent in the environment [2,3]. Of the various forms of PAHs in crude oil, 16 PAHs including naphthalene (NAP) are considered as priority pollutants by the environmental protection agencies [4][5][6].…”

We compared the ability of two bacterial strains, Paenibacillus polymyxa A26 and P. polymyxa A26Sfp, for biodegradation of naphthalene (NAP). The studies were performed under simulated laboratory conditions, in liquid medium and soil with different carbon sources, pH and salt contents. Changes in the luminescence inhibition of Aliivibrio fischeri, as an indicator of the baseline toxicity, were observed in degradation mixtures during 7 days of incubation. While both strains expressed the best growth and NAP degradation ability in the minimal salt medium containing sucrose and 5% NaCl at pH 7 and 8, the mutant strain remained effective even under extreme conditions. A26Sfp was found to be an efficient and potentially industrially important polycyclic aromatic hydrocarbon degradation strain. Its extracellular polysaccharide production is 30%, and glucan production is twice that of the wild type A 26. The surface tension reduction ability was ascertained as 25–30% increased emulsification ability.
