Recent studies using bottles as tracers have shown that illegal dumping from ships is responsible for the rapid increase in drink bottles washing up on oceanic islands and at remote continental beaches away from local litter inputs. However, these studies have been in areas with moderate to high levels of shipping activity. I examined bottles stranded on the Pitcairn Islands in the central South Pacific, which are far from major shipping routes. Drink bottles from Asia dominated, with most coming from China. The top four brands (three Chinese and one multinational) were the same as at Tristan da Cunha in the central South Atlantic Ocean, which lies on the shipping route between South America and Asia. Bottle ages also were similar at Pitcairn and Tristan, indicating that vessels are the main source of bottles at both islands. Stricter controls are needed to reduce illegal dumping of plastics at sea.
最近使用瓶子作为示踪剂的研究表明，船只非法倾倒垃圾是导致海洋岛屿和远离当地垃圾输入的偏远大陆海滩上饮料瓶快速增加的原因。然而，这些研究都是在航运活动中度到高度活跃的地区进行的。我检查了南太平洋中部皮特凯恩群岛上搁浅的瓶子，这些瓶子远离主要的航运路线。亚洲的饮料瓶占主导地位，其中大部分来自中国。排名前四的品牌（三个中国品牌和一个跨国品牌）与南大西洋中的特里斯坦达库尼亚相同，该岛位于南美洲和亚洲之间的航运路线上。皮特凯恩和特里斯坦的瓶子年龄也相似，这表明船只在这两个岛屿上都是瓶子的主要来源。需要加强控制，减少海上非法倾倒塑料。
