Seasonal and spatial variations of marine litter on the south-eastern Black Sea coast

The south-eastern Black Sea coast in Turkey was evaluated for marine litter composition and density covering nine beaches during four seasons. The marine litter (> 2 cm in size), was collected from the coast and categorized into material and usage categories. The data analysis showed that plastic was the most abundant litter (≥ 61.65%) by count and weight followed by styrofoam and fabric. The marine litter density ranged from 0.03 to 0.58 with a mean (± SD) of 0.16 ± 0.02 items/m2 by count. Based on weight, it varied between 0.44 and 14.74 g/m2 with 3.35 ± 1.63. The east side had a higher marine litter density than the west side with significant differences between beaches. The variations due to different seasons were not significant for any beach. The results of this study should provide baseline information about the coastal marine pollution and will assist the mitigation strategies.

Marine Litter Quantification in the Black Sea: A Pilot Assessment

Various programs and organizations (IMO, UNEP, IOC UNESCO, FAO) and recently the EU MSFD recognized marine litter (ML) as an issue of global threat from environmental, economic, human health and safety, and aesthetic aspect. Among the efforts to combat the problem adequate monitoring and application of harmonized methodological approaches for quantification are essential. This research presents the results of a pilot assessment of bottom ML in the Black Sea during the MISIS Project Joint Black Sea Cruise (22–31 August, 2013) along 3 transects in the NW Black Sea. The aim of the present study is a pilot quantitative assessment of bottom.

First evaluation of neustonic microplastics in Black Sea waters

Highlights

•Values of neustonic microplastic are reported for the first time in the Black Sea.
•Microplastics (<5 mm) were found in 92% of the neustonic samples.
•The primary types were fibres and no micro beads were found.
•Mean microplastic concentrations were 1.2 × 103 par. m−3 in November of 2014 and 0.6 × 103 par. m−3 in February of 2015.
