MAIN SPILLS OF DIESEL OIL AND FUEL OILS IN MANGROVE ECOSYSTEMS IN BRAZIL, FROM 1975 TO 2022 (Atena Editora)

Abstract

Oil spills in coastal and marine environments have been frequent from the second half of the 20th century to the first decades of the 21st century, resulting in varied socio-environmental impacts on mangrove ecosystems, estuaries and beaches. Port areas, marinas, and areas where the supply and maintenance of automotive, road, rail and boat vehicles are carried out, in addition to fuel distribution stations, are also prone to leaks, causing percolation of oil residue and long-term bioaccumulation. term, even in small quantities.On the other hand, large spills result in more persistent damage to affected ecosystems. In some regions, mangroves share space with port areas, refineries and pipelines, being exposed to leaks and accidents, affecting their inestimable environmental, economic and ecological importance.We sought to identify the main spills that occurred with diesel oil and fuel oils, which reached estuaries and mangroves on the Brazilian coast between the years 1975 to 2022 and to discuss the ecotoxicological and ecophysiological evidence of the presence of diesel oil in these ecosystems. Some accidents and spills with crude oil were also included only in the temporal analysis, given their significant relevance both in terms of volume spilled and in terms of extension of the affected coastal zone.Data, metadata and document analysis were used, including scientific articles, technical reports from public or private companies in the environment, sanitation, academic reports and from government public managers, academic dissertations, legal processes, among others. The results showed that diesel oil accidents are among the most frequent in chemical and petrochemical waterway terminals and caused severe damage to mangroves, other coastal ecosystems and the human population.
