This study aims to provide baseline data on microplastic (MP) concentrations in beach and seabed sediments of the SW Black Sea coast, and to identify possible sources of MP pollution in the area. MP concentrations in beach sediments in urbanised coastal areas, as well as in all seabed sediments, were on average higher than in other parts of the Black Sea and most other European seas. Urban coastal areas showed the highest average MP concentrations (mean ± SD): 464.44 ± 272.50 MP·kg dry sediment in beach samples, 825.93 ± 396.30 MP·kg dry sediment in seabed samples, while coastal sediments in an area with no local anthropogenic activities had significantly lower average MP concentrations: 84.44 ± 147.57 MP·kg in beach samples, and 550.62 ± 245.71 MP·kg in seabed samples. Possible identified sources of MPs include sewage water discharges, urban waste, coastal fisheries and aquaculture, as well as accumulation of marine litter on beaches and in adjacent offshore areas, serving as sources of secondary MP pollution.
本研究旨在提供黑海西南海岸海滩和海底沉积物中微塑料（MP）浓度的基线数据，并确定该地区 MP 污染的可能来源。在城市化沿海地区的海滩沉积物以及所有海底沉积物中的 MP 浓度平均值均高于黑海其他地区和大多数其他欧洲海域。城市沿海地区的 MP 浓度平均值最高（平均值 ± 标准差）：海滩样本中为 464.44 ± 272.50 MP·kg 干沉积物，海底样本中为 825.93 ± 396.30 MP·kg 干沉积物，而无当地人为活动的沿海沉积物中的 MP 浓度平均值明显较低：海滩样本中为 84.44 ± 147.57 MP·kg，海底样本中为 550.62 ± 245.71 MP·kg。可能的 MPs 来源包括污水排放、城市废物、沿海渔业和水产养殖，以及海滩和附近近海地区海洋垃圾的积累，这些都是二次 MP 污染的来源。
