Resumo
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.
