Abstract

The pollution of beach litter was seasonally evaluated in a selected beach in the West Mediterranean Region of Turkey between December 2019 and September 2020. Beach litter survey was carried out seasonally according to 'Guidance on Monitoring of Marine Litter in European Seas' published by European Marine Strategy Framework Directive Technical Subgroup on Marine Litter. During the study, a total of 2.324 items and 105.44 kg were collected. The average litter density was 581.0 +/- 60.04 items/m(2) and 26.36 +/- 0.85 g/m(2). The results indicated that the most common type of litter were plastic/polystyrene (35%), unidentifiable (18%) followed by cloth/textile (16%). Litter density showed significant seasonal differences with the highest in summer (P < 0.05). Homa beach was classified as "dirty" according to Clean Coast Index. It was observed that the litter in the region averagely consisted of mixed packaging litter (24.25%), fisheries related litter (19%) and unclassified litter (15.25%) items. Our results show that the coast of Homa Lagoon exposed to a significant amount of marine litter pollution originated from land-based sources. This study provides further evidence that there is a significant litter pollution in the West Mediterranean Sea of Turkey and that the main component are plastics, which pose a great treat to the Mediterranean Sea environments.
