Abstract

Abstract: 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 3 ) 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. Graphical abstract: Unlabelled Image Highlights: Microplastic (MP) pollution along the Israeli coastal line is quantified. MP fragments and films were the predominant MP onshore contaminants. Polyethylene and polypropylene were the most abundant onshore MPs. Sites located close to river estuaries showed elevated contamination levels. MP surfaces were covered with organic and inorganic substances.
