Plastic pollution is a global emerging concern, but in the Arctic Ocean, role of plastisphere as potential carrier pathogens and antibiotic-resistant bacteria unknown yet. An initial assessment spread these target through their colonization plastic particles, attributed to micro-sized fraction (less than 5 mm, named microplastics, MPs), was carried out across 75° N transect (Greenland Sea). To fill knowledge gaps regarding bacterial community associated withmicroplastics (MPs)—belonging so-called “plastisphere”—and risks related spread, our study focused on abundance taxonomic composition plastisphere, including pathogenic bacteria, using culture-dependent approach. MPs particles were collected Manta net, decimal dilutions cultured Marine agar plates estimate culturable heterotrophic bacteria. For search species (Escherichia coli, Enterococcus spp., Salmonella potentially Vibrio Staphylococcus aureus), small volumes inoculated into selective culture media aspread plate directly or after enrichment. Screening antibiotic susceptibility profiles isolates performed assess presence The dominated by members phyla Gammaproteobacteria Actinobacteria, with assigned genera Psychrobacter, Pseudoalteromonas, Shewanella, Arthrobacter.

The assessment of plastic pollution due to microplastics (MPs) and nanoparticles (NPs) was performed for the first time on water samples from four natural sites located near beaches Krk Island, Croatia, namely Melska, Črnika, rt Šilo, Zala. MP NP occurrence investigated collected during December 2022 June 2023, using bulk method followed by filtration stainless-steel sieves digestion process. Factor analysis Spearman’s correlation revealed that percentage fragments correlated well with salinity (ρ = 0.76, p < 0.05) filaments brown MPs 0.80, 0.05). monitoring throughout sampling periods generally showed a decrease in abundance as size increased. presence indicated potential contributions wastewater outlets, particularly household washing machines, either directly residents or tourists abandoned fishing nets. increased concentration NPs over could signify continuous fragmentation degradation biofilm formation their surface. These findings potentially be explained implemented waste measures along coast which 30 October 2024 officially declared zero-waste island.
