Ingestion of anthropogenic debris represents an important threat to marine turtle populations. Information has been limited to inventories of debris ingested and its consequences, but why ingestion occurs and the conditions that enable it are less understood. Here we report on the occurrence of plastic ingestion in young green turtles (Chelonia mydas) inhabiting the Río de la Plata (SW Atlantic). This estuarine area is characterized by a frontal system that accumulates anthropogenic debris. We explored exposure of green turtles to plastic and its ingestion via debris distribution, habitat use and digestive tract examination. Results indicated that there is considerable overlap of frontal accumulated plastic and core foraging areas of the animals. Exposure results in ingestion, as shown by the high frequency of plastic found in the digestive tracts. The Río de la Plata estuarine front is an area of conservation concern for young green turtles.
摄入人为碎片对海龟种群构成了重大威胁。信息仅限于摄入的碎片及其后果的清单，但为什么会发生这种情况以及使它发生的条件还不太清楚。在这里，我们报告了在栖息在拉普拉塔河（西南大西洋）的年轻绿海龟（Chelonia mydas）中发生的塑料摄入情况。这个河口地区的特点是存在一个积聚人为碎片的锋面系统。我们通过碎片分布、生境利用和消化道检查来探索绿海龟接触塑料及其摄入的情况。结果表明，锋面积聚的塑料和动物核心觅食区有相当大的重叠。接触导致摄入，因为在消化道中发现了大量的塑料。拉普拉塔河口是年轻绿海龟的一个受到保护关注的区域。
