Chapter Chemical composition of microplastics floating on the Mediterranean Sea surface
AI summary Read the abstract
This study characterized microplastic contamination in the benthic sediments of a shallow tropical reef lagoon, finding widespread particle distribution influenced by seasonal monsoon-driven circulation patterns. Concentrations were highest in low-energy depositional zones, and polymer types reflected a mixture of locally derived and oceanic transport sources.
Main objective of this study was to describe chemical composition of MP collected in surface waters of Mediterranean Sea. Samples were collected by manta net during Tara Mediterranean expedition (June–Nov.2014). Our results pointed to certain homogeneity at Mediterranean Sea scale. Main polymers collected were polyethylene (PE) (67.3±2.4%), polypropylene (20.8±2.1%), polystyrene (3.0±0.9%). Still, discrepancies, confirmed by literature, were observed at mesoscale level. Thus, in North Tyrrhenian Sea, proportion of PE was significantly lower than average value of Mediterranean Sea (57.9±10.5%).

Surface water samples from the 2014 Tara Mediterranean expedition revealed that the Mediterranean Sea's microplastic composition was relatively homogeneous at large scales, dominated by polyethylene (67%), polypropylene (21%), and polystyrene (3%). Some regional variation was observed, with the North Tyrrhenian Sea showing lower polyethylene proportions.

An evaluation of surface micro- and mesoplastic pollution in pelagic ecosystems of the Western Mediterranean Sea
AI summary Read the abstract
Researchers found that micro- and mesoplastic debris were widely and uniformly distributed across the Western Mediterranean Sea, with average surface concentrations of approximately 130,000 microplastic particles per km2 and 5,700 mesoplastic particles per km2. Fragment morphology and polymer composition analysis indicated a predominantly land-based origin for the debris.
