“…According to a different study published by [29], fibre made up the majority of all analysed samples of wild organisms, with surf clams and razor clams accounting for 80% of the sample's total MPs. Meanwhile, a research for the IOP Publishing doi:10.1088/1755-1315/1121/1/012008 6 Northern and Central Adriatic claimed that all of the examined samples of the mussel species Mytilus galloprovincialis had nylon threads [30]. Based on a comparison of the results, [30] hypothesised that nylon filaments might function as vectors for the entry of trace metals into mussels.…”

The high concentrations of plastic and plastic debris in the environment continue to rise each year as most plastics undergo minimal biological degradation. As plastics are exposed to sunlight, the atmosphere, and water, these polymers break into smaller pieces and become individual polymer molecules. In this study, the presence of microplastics (MPs) in mussels was investigated. Wild Asian green mussels (Perna viridis) samples were collected from the Pasir Putih estuary for 3 months and were categorised according to size. The density was separated using NaCl solution, and the removed soft tissues were digested with 10% KOH solution. By using FTIR spectrometry, of the particles identified in all samples collected, the majority were nylon (polyamides) in the form of fibres. The average number of fibres detected in small, medium, and large samples is 1.31, 1.05, and 0.79 items/g, respectively. Despite the widespread MPs in the environment, the actual number of MPs, particularly MP fibres, is unprecedented and expected to be higher. The abundance of MPs detected in mussels not only affects health, fecundity, and ecosystem services provided by bivalves but also presents a route for human exposure.

“…Grkovic et al (2021) studied the concentration of toxic elements in mussels aquacultured in Montenegro and revealed that moderate quantities of mussels from the examined area should be safe for consumption. Perošević-Bajčeta et al ( 2021) corroborated that for Boka Kotorska Bay, average concentrations of most elements have decreased over time, but the results of De Simone et al (2021) showed that mussels from the location nearest to a dense urban settlement were characterised by the highest content of pollutants (microplastics, textile fibres, titanium dioxide microparticles) originating from anthropogenic sources. On the contrary, in farmed mussels from the locations with probably higher phytoplankton abundance, higher carotenoid content was found.…”

Sustainability of shellfish aquaculture in Montenegro-perspectives

et al. 2022

Shellfish for human consumption is produced in excess of 15 million tons per year, accounting for roughly 14% of global marine aquaculture, with China being the largest producer (89% of world production). However, in the previous two decades, shellfish output in the European Union has been dropping. This review provides information about shellfish aquaculture in Montenegro, in Boka Kotorska Bay, where most farms belong to the group of small farms. Shellfish production in this bay is constantly increasing. Thus, with minor deviations, the production of shellfish increased from 156 tonnes, as was produced in 2012, to 246 tonnes produced in 2020. However, despite the constant growth of production, statistical data indicate that every year a large amount of shellfish is imported, and there is a need for greater production in the country. The shellfish production capacity in Montenegro is still lower than expected, despite the great potential for development. Aquaculture?s development potential is in the areas of increasing production, modernising existing farms, automating production, strengthening the competitiveness and efficiency of the sector, introducing new species, better linking aquaculture with tourism and processing, marine spatial planning, promoting aquaculture products and branding products.

“…In the present work, the hemolymphatic cells of the bivalve mollusk Mytilus galloprovincialis were used as model target cells and were in vitro exposed to label-free NPs and, for comparison, to Nile-red-labeled NPs for a time span of 6 h. Bivalve mollusks are widely utilized as bioindicator organisms in coastal and marine biomonitoring and assessment [56,57]. Their high water filtration rate due to their filter-feeding nature makes these organisms particularly vulnerable to the exposure to micro/nanoplastics [58][59][60]. Recent literature reports that polyethylene terephthalate (PET) is one of the most common polymers in Mytilus galloprovincialis in the Adriatic Sea [61,62].…”

This work contributes to fill one of the gaps regarding nanoplastic interactions with biological systems by producing polyethylene terephthalate (PET) model nanoplastics, similar to those found in the marine environment, by means of a fast top-down approach based on mechanical fragmentation. Their size distribution and morphology were characterized by laser diffraction and atomic force microscopy (AFM). Their autofluorescence was studied by spectrofluorimetry and fluorescence imaging, being a key property for the evaluation of their interaction with biota. The emission spectra of label-free nanoplastics were comparable with those of PET nanoplastics labeled with Nile red. Finally, the suitability of label-free nanoplastics for biological studies was assessed by in vitro exposure with Mytilus galloprovincialis hemolymphatic cells in a time interval up to 6 h. The nanoplastic internalization into these cells, known to be provided with phagocytic activity, was assessed by fluorescence microscopy. The obtained results underlined that the autofluorescence of the model PET nanoplastics produced in the laboratory was adequate for biological studies having the potential to overcome the disadvantages commonly associated with several fluorescent dyes, such as the tendency to also stain other organic materials different from plastics, to form aggregates due to intermolecular interactions at high concentrations with a consequent decrease in fluorescence intensity, and to dye desorption from nanoparticles. The results of the autofluorescence study provide an innovative approach for plastic risk assessment.
