Mediterranean microplastic contamination: Israel's coastline contributions
AI summary Read the abstract
Researchers monitored microplastic contamination at six sites along Israel's Mediterranean coastline, finding that sites near river estuaries (Tel Aviv and Hadera) had the highest MP concentrations, reaching 18,777 particles per square meter. Fragment and film morphologies dominated, and polyethylene was the most common polymer, pointing to urban runoff as the primary source.
This study provides an analysis of the current state of microplastic (MP) contamination along the Mediterranean coastline of Israel. Six strategic sites were monitored in this study - each representing a unique coastal environment. We conclude that Tel Aviv and Hadera, both located near stream estuaries, were highly contaminated (18,777 particles/m) with MP compared to the other locations. The MP detected included both secondary MP and pristine polymeric pellets. In-depth characterization of the MP illustrated a large percentage of both fragmented and film MP morphologies and the most common MP polymers were polyethylene and polypropylene. Further particle analysis showed that MPs were contaminated with biofilm, including microorganisms such as diatoms, as well as metal residues. Through the spatial analysis presented herein we suggest that local rivers are significant contributors to MP contamination along the Mediterranean Sea coastline of Israel and may pose a direct threat to environment and human health.

Exceptionally high abundances of microplastics in the oligotrophic Israeli Mediterranean coastal waters
AI summary Read the abstract
A coastal survey along the Israeli Mediterranean shoreline found exceptionally high microplastic concentrations — up to 1.5 million particles per square kilometer — in all samples collected. The results suggest that semi-enclosed sea basins with high population density along their shores are particularly vulnerable to microplastic accumulation.
Seasonal pulses of microplastic emissions to the Mediterranean Sea
AI summary Read the abstract
Researchers found that microplastic emissions to the Mediterranean Sea via the Na'aman stream in Israel showed strong seasonal pulses driven by rainfall, with abundances and types varying significantly before, during, and after the rainy season along the streambank and nearby beach.
Microplastics Spatiotemporal Distribution and Abundance in Water and Sediments from the Bay of Marseille
AI summary Read the abstract
A two-year study of the Bay of Marseille found microplastics in both surface waters and sediments across all seven sampling stations, with concentrations varying by season and location. Urban runoff and proximity to the coastline were associated with higher microplastic levels. The Mediterranean Sea, heavily bordered by dense populations, continues to show widespread and persistent microplastic contamination.

Researchers surveyed microplastic distribution in surface water and sediments along 47 stations of the Turkish northeastern Mediterranean coast, finding widespread contamination with fibers and fragments detected via Nile Red staining, and identifying hotspots linked to coastal urbanization and river inputs.
Microplastics pollution along the Lebanese coast (Eastern Mediterranean Basin): Occurrence in surface water, sediments and biota samples
AI summary Read the abstract
Microplastics were detected in surface water, sediments, and biota along the Lebanese coastline of the eastern Mediterranean, with concentrations reflecting local pollution pressures and sea current patterns. The study provides baseline data for a heavily urbanized and heavily impacted stretch of Mediterranean coast, confirming widespread microplastic contamination throughout the region.
