“…The MSFD and Ocean Conservancy have established protocols for monitoring the type and quantities of marine plastic litter present in the marine environment. The most used laboratory methods for marine plastic litter identification based on mass determination consist of: Fourier-transform infrared (FT-IR) spectroscopy [18,19,21,48], thermogravimetry [71], differential scanning calorimetry (DSC) [17], and density measurement [45]. These methods enable the identification of the most abundant marine plastic litter, such as PP-PE copolymer, PE, PP, PET, PVC and PS [11,17,19,21,45,65].…”

“…Marine plastic litter can originate from land-based [13,15,17,18,[45][46][47] and sea-based sources [19][20][21]26,48,49] (Table 1) and their release into the aquatic environment can be intentional or unintentional.…”

“…Fishing nets are predominantly made from poly(amide) (PA) [52] and poly(ethylene) (PE) [68]. Also, small plastic debris identified in areas where artisanal fishing takes place, is composed of poly(propylene) (PP), low-density poly(ethylene) (LDPE), and poly(ethylene terephthalate) (PET) [11,18]. These items can persist in the marine environment for a long time, posing threats to marine life and the ecosystem.…”

This review summarizes recent data related to the management of marine plastic litter to promote sustainable development. It discusses the distribution and identification of marine plastic litter, assesses the potential socio-economic and environmental impacts of these pollutants, and explores their recovery strategies, from a circular economy perspective. The main findings indicate that the majority of marine plastic litter originates from land-based sources. Current technologies and approaches for valorizing marine plastic litter include mechanical and chemical recycling, blockchain technologies by providing traceability, verification, efficiency and transparency throughout the recycling process, and public awareness programs and education. The developed policies to prevent marine plastic litter emphasize regulations and initiatives focused toward reducing plastic use and improving plastic waste management. By adopting a holistic and sustainable approach, it is possible to mitigate the environmental impact of marine plastic debris while simultaneously creating economic opportunities.

“…Since no single analytical method is able to obtain the physical (size, shape, and color) and chemical (polymer type) characteristics of MPs in a single step, the combination of several parallel approaches should be applied and considered. The most identified polymers in marine environments are PP and PE [31,34,48], PET [49], PS [50], and alkyd resins from marine coatings [32], as these are the most massively produced polymers worldwide.…”

Microplastics (MPs) and nanoplastics (NPs) both represent significant concerns in environmental sciences. This paper aims to develop a convenient and efficient methodology for the detection and measurement of MPs and nanoparticles from surface seawater and to apply it to the water samples collected from the UNESCO site of Venice and its lagoon, more precisely in the Venice-Lido Port Inlet, Grand Canal under Rialto Bridge, and Saint Marc basin. In this study, MPs were analyzed through optical microscopy for their relative abundance and characterized based on their color, shape, and size classes, while the concentration and the mean of nanoparticles were estimated via the Nanoparticle Tracking Analysis technique. Bulk seawater sampling, combined with filtration through a cascade of stainless-steel sieves and subsequent digestion, facilitates the detection of MPs of relatively small sizes (size classes distribution: >1 mm, 1000–250 μm, 250–125 μm, 125–90 μm, and 90–32 μm), similar to the size of MPs ingested by marine invertebrates and fishes. A protocol for minimizing interference from non-plastic nanoparticles through evaporation, digestion, and filtration processes was proposed to enrich the sample for NPs. The findings contribute to the understanding of the extent and characteristics of MPs and nanoparticle pollution in the Venice Lagoon seawater, highlighting the potential environmental risks associated with these pollutants and the need for coordinated approaches to mitigate them. This article is based on scientific research carried out within the framework of the H2020 In-No-Plastic—Innovative approaches towards prevention, removal and reuse of marine plastic litter project (G.A. ID no. 101000612).
