We studied the ten most frequently encountered litter items from the seafloor in European seas to advance actions and inform future mitigation measures to reduce marine litter and the associated social, economic and environmental impacts it has on European seas and beyond. Data were collected during trawl surveys from 2012 to 2020 as part of national and regional marine litter monitoring programmes in the Greater North Sea (5652 trawls), Celtic Seas (3505), Bay of Biscay (651), and Baltic Sea (3688). A Bayesian approach is used to quantify the variation in the item rankings. Overall, plastic items predominate in the top positions in each area. Synthetic rope, plastic sheets, monofilament fishing line and plastic bags occupy four of the top five positions for each of the Greater North Sea, Celtic Seas and the Bay of Biscay. Items from fishing and rope (representing mainly other maritime activities) are strongly represented in the top ten lists from three of our four areas, with synthetic rope, fishing nets, and tangled and untangled monofilament fishing line listed in the top seven positions for the Greater North Sea, Celtic Seas and the Bay of Biscay. The top ten items in the Baltic Sea are of a different profile to the other regions, but the most commonly caught items are still predominantly plastic, with plastic sheets, other plastic items and plastic bags occupying three of the top four positions. The findings in this study highlight the need to address sea-based sources to try and eliminate litter from fishing and maritime activities. Measures such as improved port reception facilities, marking of fishing gear, promoting reporting of the loss of fishing gear and increasing public awareness should be introduced.
我们研究了欧洲海域海底最常见的十种垃圾物品，以推动相关行动，并为未来的缓解措施提供参考，从而减少海洋垃圾及其对欧洲海域及其他地区造成的相关社会、经济和环境影响。作为大北海（5652次拖网调查）、凯尔特海（3505次）、比斯开湾（651次）和波罗的海（3688次）国家和区域海洋垃圾监测计划的一部分，数据于2012年至2020年在拖网调查期间收集。采用贝叶斯方法来量化物品排名的变化。总体而言，塑料物品在每个区域的排名中占据主导地位。合成绳、塑料片、单丝钓鱼线和塑料袋在大北海、凯尔特海和比斯开湾的排名中占据前五名中的四个位置。来自渔业和绳索（主要代表其他海上活动）的物品在我们四个区域中的三个区域的前十名单中占很大比例，合成绳、渔网以及缠结和未缠结的单丝钓鱼线在大北海、凯尔特海和比斯开湾的排名中位列前七。波罗的海的前十种物品与其他区域的情况不同，但最常捕获的物品仍然主要是塑料，塑料片、其他塑料制品和塑料袋占据了前四名中的三个位置。本研究的结果凸显了应对海上来源以试图消除渔业和海上活动产生的垃圾的必要性。应采取诸如改善港口接收设施、标记渔具、促进报告渔具丢失情况以及提高公众意识等措施。
