Marine litter is a threat to marine life and an economic burden for coastal communities, but efforts to address the issue are hampered by the lack of data for many countries. We performed the first harmonized assessment of seafloor litter (trawl and visual surveys) in six countries of the Adriatic-Ionian macroregion. Seafloor litter showed an uneven distribution throughout the area, with large differences in litter densities and composition among countries and locations. An emerging problem in the area resulted in short-term & single-use objects that represented the largest fraction of litter. Packaging was the economic sector contributing most to seafloor litter on the continental shelf and upper slope, while in some areas aquaculture (mussel farming) represented a key activity producing marine litter. In coastal areas and bays (e.g. Boka Kotorska bay, Montenegro), seafloor litter was mainly related to construction activities and electronic goods, which are a consequence of fly-tipping/illegal dumping.
海洋垃圾对海洋生物构成威胁，也是沿海社区的经济负担，但由于许多国家缺乏数据，解决这一问题的努力受到阻碍。我们对亚得里亚海-爱奥尼亚海大区的六个国家的海底垃圾（拖网和视觉调查）进行了首次协调评估。海底垃圾在整个地区的分布不均匀，各国和各地点之间的垃圾密度和组成存在很大差异。该地区出现的一个新问题是短期和一次性物品，它们占垃圾的比例最大。包装是对大陆架和上斜坡海底垃圾贡献最大的经济部门，而在一些地区，水产养殖（贻贝养殖）是产生海洋垃圾的主要活动。在沿海地区和海湾（如黑山的博卡科托尔斯卡湾），海底垃圾主要与建筑活动和电子产品有关，这是乱倒垃圾/非法倾倒的后果。
