Beaches are fundamental habitats that regulate the functioning of several coastal processes and key areas contributing to national and local budgets. In this study we provide the first large-scale systematic survey of anthropogenic litter on Brazilian beaches, covering a total of 35 degrees of latitude, recording the litter type, its use and size. Plastic comprised the most abundant litter type, followed by cigarette butts and paper. Small pieces (<5 cm) were dominant among litter size-classes and food-related use was associated to most litter recorded types. Generalized additive models showed that proximity to estuarine run-offs was the main driver to beach litter accumulation, reinforcing river drainages as the primary route of litter coastal pollution. Also, the Clean-Coast Index evidenced there was not a pattern of beach litter pollution among regions, which denotes that actions regarding marine pollution must be taken by all state governances of the country.
海滩是基本的栖息地，调节着多种沿海过程的功能，也是为国家和地方预算做出重要贡献的关键区域。在这项研究中，我们首次对巴西海滩上的人为垃圾进行了大规模的系统调查，共涵盖了 35 度的纬度，记录了垃圾的类型、用途和大小。塑料是最丰富的垃圾类型，其次是烟头和纸。小碎片（<5 厘米）在垃圾大小类别中占主导地位，与记录的大多数垃圾类型相关的是与食物有关的用途。广义加性模型表明，靠近河口径流是海滩垃圾堆积的主要驱动因素，这进一步证实了河流排水系统是沿海污染的主要途径。此外，清洁海岸指数表明，各地区之间没有海滩垃圾污染的模式，这表明必须由国家所有州政府采取行动来解决海洋污染问题。
