Benthic marine litter along the Portuguese coast, was recorded in 14 trips on stern trawlers covering a distance of 2117 km and an area of 56.2 km(2), average depth range 90-349 m. 2034 items of marine litter were registered, 76% were plastics and 38.6% were originated from fishing related activities. Plastic was present in all the trawls and had the highest average density of all litter categories, 50 items km(-2). The highest density of marine litter (178.9 ± 64.0 items km(-2)) was found in the proximity of the Tagus river mouth, probably related to the high population density in the Lisbon metropolitan area. This study highlights the need to raise fishermen awareness for the adoption of good environmental practices that will contribute to the reduction of marine litter.
在葡萄牙海岸进行的底栖海洋垃圾调查中，研究人员乘坐尾拖网渔船进行了14次航行，航程达2117公里，覆盖面积56.2平方公里，平均深度范围为90 - 349米。共记录到2034件海洋垃圾，其中76%为塑料垃圾，38.6%源自与渔业相关的活动。所有拖网捕捞中均发现了塑料垃圾，其在所有垃圾类别中的平均密度最高，为每平方公里50件。在塔霍河河口附近发现了最高密度的海洋垃圾（178.9 ± 64.0件/平方公里），这可能与里斯本大都市区的高人口密度有关。本研究强调有必要提高渔民对采用良好环境做法的认识，这将有助于减少海洋垃圾。
