How much do we know about the microplastic distribution in the Mediterranean Sea: A comprehensive review
AI summary Read the abstract
This comprehensive review analyzed 284 studies on microplastic pollution across the Mediterranean and Black Seas from 2012 to 2023. Researchers found that microplastic contamination is widespread across surface water, sediment, and marine organisms, with fibers and polyethylene being the most common types. The review highlights important gaps in standardized sampling methods and calls for more consistent monitoring approaches to better understand the scope of Mediterranean microplastic pollution.
The Mediterranean Sea is one of the most heavily polluted regions. Here we comprehensively review the current state of microplastic pollution in the Mediterranean Sea and the Black Sea. A total of 284 studies published between 2012 and 2023 were analyzed, revealing a continuous increase in research efforts. Our review encompassed microplastic monitoring studies across five environmental matrices: the sea surface, water column, intertidal sediment, bottom sediment, and biota, with a predominant focus observed in biota-related studies with fish, molluscs, crustaceans, and echinoderms being the primary focus. The study found that species such as Mullus barbatus, Mytilus galloprovincialis, Nephrops norvegicus, and Holothuria tubulosa are frequently studied species. The review also emphasizes the lack of standardized methodologies across studies, which hampers the comparability of results and the synthesis of data. The findings of this study provide a critical evaluation of the current research landscape and identify significant knowledge gaps, particularly in the underrepresented southern Mediterranean and Black Sea regions, calling for more balanced research efforts and methodological consistency in future studies.

Are research methods shaping our understanding of microplastic pollution? A literature review on the seawater and sediment bodies of the Mediterranean Sea
AI summary Read the abstract
This systematic review examines microplastic research methods used to study pollution in the Mediterranean Sea. The researchers found that inconsistent methods across studies make it difficult to compare results and understand the true scale of contamination. Standardizing how we measure microplastics is essential for accurately assessing the risks these particles pose to marine ecosystems and the humans who depend on them.
Microplastic Pollution Profile in the Black Sea Region
AI summary Read the abstract
Researchers reviewed 100 peer-reviewed articles to create a comprehensive pollution profile of microplastics in the Black Sea region. They found that microplastics have been documented across multiple environmental compartments in the region, with plastic products from various industrial sectors contributing to contamination. The review provides an overview of the current state of knowledge on microplastic distribution and sources specific to this ecologically important semi-enclosed sea.
Distribution and characterization of microplastics in the coastal areas of the Mediterranean Sea
AI summary Read the abstract
Researchers investigated the distribution and characterization of microplastics in coastal surface waters of the Mediterranean Sea as part of the MICROPLASMED project, examining the relationship between microplastic pollution levels and the composition of marine microbiomes as potential biological indicators. Surface water samples were collected across Mediterranean sites to characterize microplastic abundance and assess how varying pollution levels influence microbial community diversity and abundance.
Microplastics in Mediterranean coastal area: toxicity and impact for the environment and human health
AI summary Read the abstract
This review examined microplastic and nanoplastic pollution across the Mediterranean Sea, finding contamination in surface water, sediments, deep seafloor, and seafood consumed by humans. Researchers highlighted that coastal zones are the most contaminated areas due to population pressure, tourism, and marine traffic, and noted that standardized analytical protocols are still needed for reliable identification and quantification of these particles.
Exploring the Microplastics Distribution in the Bottom Sediments of the Western Black Sea
AI summary Read the abstract
Researchers surveyed the bottom sediments of the western Black Sea and found microplastic particles at every sampling site, with fibers the most common shape and polyethylene/polypropylene the most common polymer types. The widespread presence across the shelf zone, without a clear pattern tied to distance from shore, suggests diffuse anthropogenic inputs rather than a single point source — a finding that complicates clean-up and monitoring efforts for this semi-enclosed sea.
