Anthropogenic Marine Litter (AML) accumulating on beaches causes damage to coastal ecosystems and high costs to local communities. Volunteers sampled AML on 130 beaches along the central and southern East Pacific coasts, with AML densities ranging from 0.46 to 2.26 items m in the different countries. AML composition was dominated by plastics and cigarette butts, the latter especially in Mexico and Chile. The accumulation of AML in the upper zones of the beaches and substantial proportions of cigarette butts, glass and metal pointed mainly to local sources. Statistical modelling of litter sources on continental beaches revealed that tourism, access and related infrastructure (e.g. parking lots) best explained AML densities, while plastic densities were also influenced by the distance from river mouths and national Gross Domestic Product. Large-scale monitoring can be a useful tool to evaluate the effectiveness of public policies that should primarily focus on land sources.
人为海洋垃圾（AML）在海滩上的积累对沿海生态系统造成了破坏，并给当地社区带来了高昂的成本。志愿者在中太平洋和南太平洋东海岸的 130 个海滩上对 AML 进行了采样，不同国家的 AML 密度范围从每平方米 0.46 到 2.26 个物品。AML 的组成主要是塑料和烟头，后者在墨西哥和智利尤为突出。AML 在海滩上部区域的积累以及烟头、玻璃和金属的大量存在主要指向当地来源。对大陆海滩上垃圾来源的统计模型表明，旅游、通道和相关基础设施（如停车场）最能解释 AML 密度，而塑料密度也受到河口距离和国家国内生产总值的影响。大规模监测可以成为评估公共政策有效性的有用工具，这些政策应主要侧重于陆源。
