Abstract
The present study was performed on Eastern Black Sea Region coasts and trawling areas. Its aime was to investigate the amount and composition of marine litter and its seasonal changes. The beach surveys were conducted on nine selected stations during four seasons. Also trawl surveys were conducted on December 2012 on trawling areas. All litter items greater than 2 cm diameter were collected and categorized according to their material and usage categories. A total of 36,880 m2 beach area was surveyed and 5,690 pieces of litter with 108.28 kg weight were collected during the study. Taking into account the seasonal average values, with 0.21 items/m2 autumn was the most abundant season while spring was the merest with 0.13 items/m2. Plastic (71.85%) was the most abundant material followed by nylon (16.90%) and paper (3.76%) according to sum of seasons. Composite materials (1.48%) which consist of at least two different materials was the less abundant. The most common usage category was foams (26.43%) followed by beverage (24.38%) and undefined (23.93%) while clothing (2.21%) was the less abundant. According to trawl surveys nylon (65.67%) was the most abundant material while the glass (1.49%) and metal (1.49%) was least. The most abundant usage category was undefined (40.32%) while clothing (3.52%) was least.
