The article presents the results of coastal litter monitoring on the beaches of the Black Sea from 2016 to 2021. The study was conducted on five beaches of the northeastern Black Sea coast, including urban and suburban areas. The Marine Strategy Framework Directive (MSFD) methodology of the European Commission was used for the collection and classification of litter items. During 13 monitoring sessions, a total of 2633 litter items (108 types, 8 categories) were identified, with plastic being the predominant component, averaging 71.7% of the total litter volume. The second predominant category was metal, averaging 8.2% of the found litter. The litter density varied from 47.66 pcs./100 m to 1163 pcs./100 m. The litter density median was 118.26 pcs./100 m on all studied beaches. The inter-annual variability in the litter amount on the beaches shows a decreasing trend in all monitored areas with pronounced peaks in the summer and winter seasons. The main source of the coastal litter pollution was recreational activities, the impact of which was aggravated by lack of developed waste management infrastructure as well as by the proximity of transport routes. The obtained data highlight the necessity of continued monitoring and implementation of measures to reduce pollution, such as improving waste management systems and reducing plastic production and usage. These data can also contribute to legislative and practical initiatives for the protection of the Black Sea marine ecosystems as developed both by the government and people at large.
