Marine litter is recognized as a global marine environmental problem. Beach litter surveys are used to monitor litter pollution and can be used to determine the origins of litter which can be used for the improvement of waste management. This research studied abundance, composition and sources of marine litter on the beach during one year period in four seasons in Vodenjak cove, central Croatian Adriatic. The results showed that this part of the coast was very dirty according to Clean Coast Index (48.4) and the litter density was 2.55 items/m². The highest density was recorded during winter (4.24 items/m²). The largest part of the collected litter belonged to the category of artificial polymer materials and accounts for 94.88%. Litter sources have not been identified for 43.77% of the total waste collected, while 34.38% of waste has been identified as originating from land-based sources such as poor waste management, tourism and recreational activities. Single-use plastic items accounted for 31.35% of all items collected.

克罗地亚亚得里亚海中部Iž岛Vodenjak湾的海洋垃圾监测与分析

海洋垃圾被认为是全球海洋环境问题。沙滩垃圾调查可用于监测垃圾污染，并可用于确定垃圾来源，这些垃圾可用于改善废物管理。这项研究研究了克罗地亚亚得里亚海中部Vodenjak湾在四个季节中一年中海滩上海洋垃圾的丰度，组成和来源。结果表明，根据清洁海岸指数（48.4），该部分海岸很脏，垃圾密度为2.55个/ m ²。冬季记录到最高密度（4.24个/ m ²）。收集到的垃圾中最大部分属于人造聚合物材料，占94.88％。在收集到的总废物中，未查明垃圾来源占43.77％，而已查明废物的34.38％来自陆基资源，例如废物管理不善，旅游和娱乐活动。一次性使用的塑料物品占收集的所有物品的31.35％。
