We examined the hypothesis that in an emerging economy such as Chile the abundances of Anthropogenic Marine Debris (AMD) on beaches are increasing over time. The citizen science program Científicos de la Basura ("Litter Scientists") conducted three national surveys (2008, 2012 and 2016) to determine AMD composition, abundance, spatial patterns and temporal trends. AMD was found on all beaches along the entire Chilean coast. Highest percentages of AMD in all surveys were plastics and cigarette butts, which can be attributed to local sources (i.e. beach users). The Antofagasta region in northern Chile had the highest abundance of AMD compared with all other zones. Higher abundances of AMD were found at the upper stations from almost all zones. No significant tendency of increasing or decreasing AMD densities was observed during the 8years covered by our study, which suggests that economic development alone cannot explain temporal trends in AMD densities.
我们检验了这样一个假设，即在智利这样一个新兴经济体中，海滩上人为海洋垃圾（AMD）的丰度随着时间的推移而增加。公民科学计划“垃圾科学家”（Científicos de la Basura）进行了三次全国性调查（2008 年、2012 年和 2016 年），以确定 AMD 的组成、丰度、空间模式和时间趋势。在智利沿海的所有海滩上都发现了 AMD。在所有调查中，AMD 的最高比例是塑料和烟头，这可以归因于当地的来源（即海滩使用者）。与其他所有区域相比，智利北部的安托法加斯塔地区的 AMD 丰度最高。在几乎所有区域的上游站都发现了更高丰度的 AMD。在我们研究涵盖的 8 年期间，AMD 密度没有观察到明显的增加或减少趋势，这表明经济发展本身并不能解释 AMD 密度的时间趋势。
