Ingestion of solid wastes by juvenile green turtles, Chelonia mydas (L. 1758), in the eastern Rio de Janeiro state coast, Brazil

This paper analyzed the solid wastes of anthropogenic origin obtained from the stomach contents of juvenile green turtles, Chelonia mydas, on the eastern Rio de Janeiro state coast, southeastern Brazil (22º50’S – 23º00’S). Between June 2009 and May 2010, the stomach contents of 49 specimens stranded on beaches were analyzed. Solid wastes were recorded in 29 stomach contents (59.2%) and more than one category of wastes was found out in 22 samples. Plastic bags, categorized as flexible plastic materials, achieved the greatest occurrence frequency (96.5%). Perhaps, these wastes came from the disposal of garbage bags, raffia bags, commercial shop bags and various packaging. Wastes related to manufacture of fishing equipment were also often reported, such as nylon yarns, rubber, ropes, Styrofoam, and fishhooks. The region is an area of regular occurrence of C. mydas and the relatively large intake of solid wastes deposited in the environment poses a risk to the conservation of this species
