Aspects of higly microplastic contamination in the Atlantic Forest estuary
2023 - PARRA, DUCLERC F.; GIMILIANI, GIOVANA; SANTOS, JACINETE L. dos; COTRIM, MARYCEL E.B.
The Atlantic Forest is one of the richest regions in terms of biodiversity in the world. Originally the biome covered about 15% of the national territory. Currently, only about 12.4% (SOS MATA ATLÂNTICA, 2021) of well-preserved forest remnants remain in the country [1]. Regarding mangrove areas, in the state of São Paulo there are about 223 km², according to the Atlas of mangroves in Brazil, with about 120.5 km² of this total in Baixada Santista. Analyzes of sediments collected at Santos estuarine mangroves, in various points show a high concentration of microplastics generated from industrial processes or even anthropogenic activity. These solid particles based on (< 5 mm) are today one of the main environmental problems. The microplastics present in the sediment samples were quantified after drying and sieving amount limited of sediment. FTIR and micro-Raman spectroscopy identified filaments and fragments of microplastics (MPs) as commom polymer spectra. Also additives and herbicides were present in some MPs. All polymeric types identified (<5mm) have wide applications and demands by packaging, civil construction, automotive, electrical and electronics, and textile sectors.
