Ocorrência de fragmentos plásticos no conteúdo estomacal de peixes de Laranjal do Jari-AP

Abstract

Fish is a food widely consumed throughout the State of Amapá and according to Silva & Silva (2004) the municipalities of Macapá and Santana lead the ranking in fish consumption. The most consumed fish in the region are the ethnospecies Piramutaba, Filhote, Dourada, Pirarucu, Tambaqui, Tucunaré, Piranha, Pescada, Gurijuba, Pirapitinga, Traira, Acará and Acari. The municipality of Laranjal do Jari located in the upper Amapá estuary is one of the main points of fishing activity in the state (SILVA & DIAS, 2010). The extractive activity of the local population is concentrated on fishing and hunting for personal consumption and commercial exploitation. However, the municipality of Laranjal do Jari faces serious problems with basic sanitation where most of the discarded garbage ends up in the river, solid waste such as plastic, among others, has affected the local ichthyofauna. A recent study carried out by the Federal University of Pará (UFPA) proved the presence of plastic inside the bodies of 98% of fish that live in springs, rivers and streams in the Amazon. This research aims to analyze wheter the presence of plastic fragments occurs in the stomach contents of fish from Laranjal do Jari river that flows through the municipality, the fish will be taken to the laboratory and the presence will be identified of these fragments together with descriptive and linear regression analysis. In view of the above, it is important to identify their impact on nature as nature is one of the main disposal sites for these wastes released directly into the environment, mainly from beauty and personal hygiene products such waste is classified according to its size, with nano plastics being those that are less than 1 μm in size called Microplastics and Microplastics those that are between 25mn and 1m in size.
