Sul, Juliana Assunção Ivar do; Santos, Isaac Rodrigues dos; Friedrich, Ana Cláudia; Matthiensen, Alexandre; Fillmann, Gilberto


Sea turtles are highly susceptible to plastic ingestion and entanglement. Beach debris were surveyed along the most important sea turtle nesting beaches in Brazil (Costa dos Coqueiros, Bahia State). No significant differences among developed and undeveloped beaches were observed in terms of total number of items. Local sources (tourism activities) represented 70% of debris on developed beaches, where cigarette butts, straws, paper fragments, soft plastic fragments, and food packaging were the most abundant items. Non-local sources (domestic and fishing activities) accounted for about 70% of debris on undeveloped beaches, where the most abundant items were rigid plastic fragments, ropes, soft plastic fragments, caps,and polystyrene. The projected surface area of beach debris did not vary among developed and undeveloped beaches.Overseas containers accounted for about 25% of regional plastic pollution, implying that international pollutionprevention agreements are not being respected off the Brazilian coast.
