Abstract

Seabirds are now facing plastic pollution worldwide, but there is a lack of data on plastic ingestion at the level of the Black Sea's unique basin.

We present a first complete assessment of the ingested plastic by two marine bird species (Larus cachinnans and Phalacrocorax carbo). Plastic fragments (>1 mm) were extracted from the birds’ stomachs, analyzed, and identified using FT-IR and FT-Raman spectroscopy.

We found ingested plastic in 17.6% of individuals, with seagulls exhibiting 23.08% frequency of occurrence (FO), while in cormorants no plastic items were found. User plastics were the most common type ingested, with the off/white-clear and microplastics being the most common color and size encountered. The identified polymers were polyethylene mix (58.33%), polyethylene (33.33%) and polyamide (8.33%).

This is the first birds’ plastic ingestion study, both for Romanian and the Black Sea coastal region, highlighting the need for setting-up a seabird litter ingestion monitoring to properly mitigate plastic pollution in the Black Sea.

期刊介绍： Estuarine, Coastal and Shelf Science is an international multidisciplinary journal devoted to the analysis of saline water phenomena ranging from the outer edge of the continental shelf to the upper limits of the tidal zone. The journal provides a unique forum, unifying the multidisciplinary approaches to the study of the oceanography of estuaries, coastal zones, and continental shelf seas. It features original research papers, review papers and short communications treating such disciplines as zoology, botany, geology, sedimentology, physical oceanography.
