Details of Floating Microplastics


Dataset identification

Title of datasetFloating Microplastics
Narrative summary of datasetFloating Microplastics data collected in the N.Ionian Sea - S.Adriatic waters in the framework of the DeFishGear project 2014-2015
Summary of processing methodologyMacro- and microplastics abundances were determined in the Adriatic Sea following the MSFD TG10 protocol. The studied areas included populated gulfs, river outlets and o?shore waters in ?ve Adriatic countries. The use of small ships enabled us to detect small sized plastics (2.5–5 cm) and record average macroplastics densities of 251 ± 601 items km-2, one order of magnitude higher than previously considered. Results from manta net tows for microplastics revealed an average abundance of 315,009 ± 568,578 items km-2(217 ± 575 g km-2). We found signi?cantly higher microplastics abundances in nearshore (=4 km) than in o?shore waters (> 4 km) and this trend seems to a?ect also the small sized macro plastic fragments (2.5–5 cm). The dominant polymers were polyethylene and polypropylene while the presence of some rare polymers and waxes used in food and dentistry indicated waste water treatment plants as potential sources of microplastics.
