This study represents an inter-institutional effort that was supported by more than 400 volunteers. We sampled Anthropogenic Marine Debris (AMD) on 26 beaches, including one beach from Galapagos Islands. AMD was mainly composed of plastics (>60%), followed by cigarette butts, paper and metal. Average AMD density on the continental beaches was 1.31 ± 1.03 items m (mean ± SD). AMD densities and the proportion of plastics were higher on some beaches located on the Gulf of Guayaquil, suggesting that many of the plastic items found on these beaches were, likely, drifted by the swift currents of the Guayas River. Additionally, the overall results indicate that most litter on continental beaches from Ecuador has local sources. Recommendations include marine pollution education and public awareness campaigns to reduce the consumption of plastic bags, as well as a ban on harmful single-use plastics.
这项研究是一项多机构合作的成果，得到了 400 多名志愿者的支持。我们在 26 个海滩上采集了人为海洋垃圾（AMD）样本，其中包括加拉帕戈斯群岛的一个海滩。AMD 主要由塑料（>60%）组成，其次是烟头、纸张和金属。大陆海滩上 AMD 的平均密度为 1.31±1.03 个/米（平均值±标准差）。位于瓜亚基尔湾的一些海滩上的 AMD 密度和塑料比例较高，这表明在这些海滩上发现的许多塑料物品很可能是被瓜亚斯河的急流冲过来的。此外，总体结果表明，厄瓜多尔大陆海滩上的大部分垃圾都有当地来源。建议包括开展海洋污染教育和公众意识运动，以减少塑料袋的使用，并禁止有害的一次性塑料。
