海洋活动是塑料废物进入海洋的重要来源。这对于渔业具有竞争力的国家（例如秘鲁）尤其重要。因此，这项研究旨在确定和量化秘鲁经济专属区内海洋来源的塑料废物在海洋中积累的主要流量。详细阐述了物质流分析，以分析秘鲁船队的塑料存量及其向海洋的释放，包括渔业，商船，游轮和船只。结果显示，2018年有2715至5584公吨的塑料垃圾进入海洋。捕鱼船队是污染最严重的，约占总量的97%。此外，渔具损失是最大的单一活动贡献，尽管其他来源，如塑料包装和二氧化碳排放，有可能成为海洋塑料污染的巨大来源。
Marine-based activities are a critical source of plastic waste into the ocean. This is particularly important in countries with a competitive fishing industry, such as Peru. Thus, this study aimed to identify and quantify the major flows of plastic waste accumulating in the ocean from ocean-based sources within the Peruvian Economic Exclusive Zone. A material flow analysis was elaborated to analyze the stock of plastic and its release to the ocean by a set of Peruvian fleets, including the fishing industry, merchant vessels, cruises, and boating vessels. Results show that in 2018 between 2715 and 5584 metric tons of plastic waste entered the ocean. The fishing fleet was the most pollutant, representing approximately 97 % of the total. Moreover, fishing gear loss represented the highest single-activity contribution, although other sources, such as plastic packaging and antifouling emissions, have the potential to become vast sources of marine plastic pollution.
