Abstract (sommario):
Heavy metals may be one of the factors causing a change in sexual structure in the settlements of mussel Mytilus galloprovincialis Lam. cultivated on the Sevastopol seaside. The aim of the work was to study the influence of Zn+2, Cd+2, Pb+2, Hg+2, Cu+2 ions on the sex inversion of cultivated mussels during spring post spawning of gonads. Chronic intoxication of female mussel at ion concentration of 2 MPC was carried out for a month in laboratory conditions. After 3 months of a natural experiment, the sex of each mollusc was individually examined by the method of visual study of gonad smears. The sex inversion of the females occurred under the influence of all heavy metals. The maximum shares of males were observed after the influence of Cu+2 and Pb+2 – 65 and 52 %, respectively. Both laboratory and natural experiments showed high toxic effect of Cu+2 and Hg+2 ions, with female mortality reaching 33 and 13 %, respectively.

Abstract (sommario):
Water is a vital natural resource for life. The metal pollution of aquatic ecosystems is increasing due to the effects of urbanization and industrialization. As a result, heavy metals contamination has become a serious threat to public health because of their toxicity, long persistence, bioaccumulation, and biomagnification in the food chain. This investigation aims to evaluate seawater's Physico-chemical quality and assess the contamination risks of Mytilus galloprovincialis mussels by Cadmium, Zinc, Iron, and Copper. The study was carried out in three stations of Saidia coast during July 2019. The seawater was analyzed for its Physico-chemical parameters, and ICP-AES determined the heavy metals content in mussels. The results show that the tested water has a pH value ranging between 7.48-7.62 with nitrate and nitrite content range between 0-4.78 mg/L, 0.007-0.181 mg/L, respectively. The recorded water conductivity and oxydability values ranged from 22 to 55 mS/cm and from 5.67 to 10.47 mg/L. The mean concentration found in the mussels were in decreasing order, Iron (13.5 mg/kg), Zinc (2.3 mg/kg), Copper (0.65 mg/kg) and Cadmium (0.02 mg/kg), respectively. The obtained results indicate that all values are below the threshold recommended by Food and agriculture organization and world health organization.

Abstract (sommario):
ABSTRACT The concentrations of the trace elements zinc (Zn), arsenic (As), manganese (Mn), copper (Cu), chromium (Cr), nickel (Ni), cobalt (Co), cadmium (Cd), lead (Pb), mercury (Hg), and iron (Fe) were examined in Mediterranean blue mussels (Mytilus galloprovincialis) from the Northern Adriatic Sea to determine whether there were site differences and seasonal variations in metal concentrations and to evaluate the potential health risks of consumption of these mussels to humans. Mussels were collected between January and October 2015 from three Slovenian shellfish harvesting areas and from a lighthouse near Debeli Rtič. The concentrations of elements were determined using inductively coupled plasma mass spectrometry. The amount of each element decreased in the following order: Fe > Zn > (As, Mn) > (Cu, Cr) > (Ni, Co) > (Cd, Pb) > Hg. Statistical analysis revealed that time, that is, the month of sampling, significantly affected the concentrations of elements in mussels (P < 0.05). The concentrations of Cr, Mn, Fe, Ni, Hg, and Pb were highest between January and March and lowest between May and September. The concentrations of other elements in mussels were not higher or lower for several consecutive months, but occasionally (some months) lower or higher content was detected. The sampling site had a statistically significant effect only on the content of Cd, Pb, and Hg in mussels (P < 0.05). The lowest level of these elements was found in mussels from Seča, and the highest levels of Hg and Pb were found in mussels from Debeli Rtič. Debeli Rtič is, among all sampling points, closest to the outflow of the Soča River that brings heavy metals into the Northern Adriatic Sea from a closed Hg mine. Because the concentrations of Pb, Cd, and Hg in all analyzed samples were below the maximum level permitted by Commission Regulation No 1881/2006, mussels were suitable for human consumption.

Abstract (sommario):
To encourage the applicability of nano-adsorbent materials for heavy metal ion removal from seawater and limit any potential side effects for marine organisms, an ecotoxicological evaluation based on a biological effect-based approach is presented. ZnCl2 (10 mg L−1) contaminated artificial seawater (ASW) was treated with newly developed eco-friendly cellulose-based nanosponges (CNS) (1.25 g L−1 for 2 h), and the cellular and tissue responses of marine mussel Mytilus galloprovincialis were measured before and after CNS treatment. A control group (ASW only) and a negative control group (CNS in ASW) were also tested. Methods: A significant recovery of Zn-induced damages in circulating immune and gill cells and mantle edges was observed in mussels exposed after CNS treatment. Genetic and chromosomal damages reversed to control levels in mussels’ gill cells (DNA integrity level, nuclear abnormalities and apoptotic cells) and hemocytes (micronuclei), in which a recovery of lysosomal membrane stability (LMS) was also observed. Damage to syphons, loss of cilia by mantle edge epithelial cells and an increase in mucous cells in ZnCl2-exposed mussels were absent in specimens after CNS treatment, in which the mantle histology resembled that of the controls. No effects were observed in mussels exposed to CNS alone. As further proof of CNS’ ability to remove Zn(II) from ASW, a significant reduction of >90% of Zn levels in ASW after CNS treatment was observed (from 6.006 to 0.510 mg L−1). Ecotoxicological evaluation confirmed the ability of CNS to remove Zn from ASW by showing a full recovery of Zn-induced toxicological responses to the levels of mussels exposed to ASW only (controls). An effect-based approach was thus proven to be useful in order to further support the environmentally safe (ecosafety) application of CNS for heavy metal removal from seawater.

Abstract (sommario):
The role of mussels in formation of water chemical composition is determined by the peculiarities of sorption and trophodynamic processes. Copper is a vital element, but of ten metals the toxic effect of which was tested for the survival of mussel and oyster embryos, copper is following mercury. Studying the regularities of copper content change during mussel ontogeny allows to determine both sanitary and hygienic risks of mussel product use during the mollusks cultivation in mariculture and the biogeochemical role in the formation of the chemical composition of the marine water near mussel farms. The purpose of this work is to determine the copper content in the organs and tissues of the mussels during seasonal course of mollusks ontogenesis, to analyze the degree of copper assimilation along the food path of mineral nutrition using the mathematical model and empirical data and to assess the influence of marine farms on the copper exchange processes in the coastal ecosystem. The mollusks were collected from the mussel farm located in the external roadstead of Sevastopol. Studying the copper content in the environment – mussel – biodeposition system, a method of atomic absorption spectroscopy with electrothermal atomization was used. A general model illustrating the process of copper exchange between the mussels and the water environment is presented. Equations for determining the degree of assimilation of metal from food (q) and the limiting coefficient of food accumulation of metal (Кп) are proposed based on the results of measurements of its concentrations in the mussels’ diet, soft tissue and their biodeposition without using radioactive trace elements. The values of the copper removal by the mussel farm were calculated. The role of cultivated mollusks in the heavy metals precipitation was shown.
