The accumulation of marine litter on beaches has a detrimental impact on the environment, human health, and recreational activities. A total of 116 monitoring surveys were conducted along the shore of the Kaliningrad region between 2019 and 2023. Sampling of anthropogenic and plastic litter (>0.5 cm) was carried out under various meteorological conditions on eight sandy beaches. The greatest abundance and mass of plastic marine litter (mean ± SE: 13.75 ± 8.61 items/m and 19.97 ± 5.92 gDW/m, correspondingly) were observed in the aftermath of storms within beach-cast accumulation stains at the shoreline, where it was intermixed with organic debris. This is two orders of magnitude greater than the plastic litter contamination obtained using the OSPAR methodology at the same beach during fine weather (0.11 ± 0.01 items/m, 0.33 ± 0.02 gDW/m). The results suggest that the most effective strategy for beach cleaning is to implement it in the post-storm period.
海滩上海洋垃圾的积累对环境、人类健康和娱乐活动都有不利影响。在 2019 年至 2023 年期间，对加里宁格勒地区的海岸进行了总计 116 次监测调查。在各种气象条件下，在 8 个沙滩上对人为和塑料垃圾（>0.5 厘米）进行了采样。在风暴过后，在海滩堆积痕迹的岸边，可以观察到最大数量和质量的塑料海洋垃圾（平均值±SE：13.75±8.61 件/米和 19.97±5.92 gDW/米，相应地），这些垃圾与有机碎屑混合在一起。这是在同一海滩天气良好时使用 OSPAR 方法获得的塑料垃圾污染的两个数量级（0.11±0.01 件/米，0.33±0.02 gDW/米）。结果表明，海滩清洁最有效的策略是在风暴后进行。
