Sea surface microplastics in Slovenian part of the Northern Adriatic
AI summary Read the abstract
Researchers conducted 17 manta trawl surveys over 20 months in the Slovenian portion of the Northern Adriatic Sea, finding a high average microplastic concentration of 406,000 particles per km2 with polyethylene dominating, and linking concentration variability to surface current patterns modeled with a Markov chain approach.
Plastics are the most common material of marine litter and have become a global pollution concern. They are persistent in the environment where they gradually degrade into increasingly smaller particles-microplastics (MP). Our study presents results of sea-surface monitoring for MP in the Slovenian part of the Trieste Bay in the Northern Adriatic Sea. In 17 trawls conducted over a 20-month period we found a high average concentration of 406×10MPparticles/km. Over 80% of the particles were identified as polyethylene. The significant variability of MP concentrations obtained on different sampling dates is explained by use of surface current maps and a recently developed Markov chain marine litter distribution model for the Adriatic Sea.

Researchers collected plastic particles from two sea surface monitoring transects near the Venice Lagoon using a manta net and characterized them by typology, dimension, color, spatial density, and chemical composition using a multi-technique analytical approach. They identified distinct subgroups of plastic micro-debris in this Northern Adriatic coastal area and documented the widespread presence of polymeric materials in surface seawater.
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.

AI summary Read the abstract
Researchers sampled surface seawater at sites near Zadar and Sibenik on the Croatian Adriatic coast and found an average microplastic concentration of 0.80 particles per cubic meter. Fibers were the most common form, consistent with findings from other global coastal studies, with secondary microplastics from wastewater discharge and fishing activities as likely sources.
