Marine litter in sediments related to ecological features in impacted sites and marine protected areas (Croatia)
AI summary Read the abstract
Researchers found that marine litter including microplastics was present in shallow sediments across Croatian Adriatic sites, with tourism-stressed areas showing higher contamination levels than marine protected areas, highlighting the influence of human pressure on plastic accumulation.
This study estimates levels of marine litter including plastics (macro-, meso- and microplastics) in sediments collected in shallow marine water from Croatia (Central Adriatic Sea). Selected sampling areas are characterized by different human pressure: Silba is highly stressed by tourism while Grebena is listed as marine protected area (MPA) of future institution. Obtained results on marine litter in sediments are correlated to ecological features recorded in each sampling site. Marine litter in collected sediments ranged within 180-528 items/kg d.w. Macroplastics were not recorded while mesoplastics were 1.3-4.8%. On a general basis, fibres are higher than microplastics. In Južni Greben, level of fragments higher than fibres was recorded. A slight significance of the factor "water depth" was evidenced by the statistical analyses exploring relationships among marine litter and ecological features. Furthermore, Silba and Grebena Islands showed a significant different assessment of size, shape and colour features. These results suggest different sources/dynamics affecting marine litter recorded in marine areas stressed by tourism compared to MPA.

Macrodebris and microplastics from beaches in Slovenia
AI summary Read the abstract
Researchers surveyed both macrodebris on beaches and microplastics in shoreline and sublittoral sediments in Slovenia, providing the first such dataset for this short Adriatic coastline. The study found plastic contamination present even in areas with low tourism activity, suggesting diffuse sources beyond local littering.

Marine litter in the Croatian part of the middle Adriatic Sea: Simultaneous assessment of floating and seabed macro and micro litter abundance and composition.
AI summary Read the abstract
Floating and seabed macro- and micro-litter in the Croatian middle Adriatic Sea were simultaneously surveyed, finding average floating micro-litter concentrations of 127,000 particles per square kilometer and seabed micro-litter of 36 particles per 100 g dry weight. The study confirms that plastic pollution is widespread at all depths in this semi-enclosed Mediterranean sea.
