Abstract: 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.
