“…Our results showed that all samples presented microplastic particles; however, the water from the North Wing area presented a higher mean of MPs (219 MP/500 mL of water) than the South Wing (97 MP/500 mL of water), and MP size ranged from 6-50 microns. In Brazil, researchers on MPs follow the global pattern, with most publications focusing on coastal and marine ecosystems [1,36,52,53].…”

“…Furthermore, their uptake and toxicity have been studied in mammalian model systems [67]. The finding suggests they can translocate across living cells to the lymphatic and/or circulatory system [68][69][70], potentially accumulating in secondary organs [71,72] or impacting the immune system [1,20]. Considering the presence of MPs in the environment and the presence of MPs in drinking water, future studies are necessary to address its consequences for human and animal health.…”

“…Plastic pollution is a rapidly growing environmental and human health crisis, with no sign of improvement [1][2][3][4]. According to He et al (2020), from 2012 to 2020, the number of studies on plastic pollution increased from 19 to 1221 per year [5,6], and plastic pollution, from macro to nano size (macroplastics: 5-50 cm; mesoplastics: 0.5-5 cm; microplastics: 1 µm-5 mm; and nanoplastics: <1 µm) [7], has been documented even in the most remote biomes of the planet [8][9][10][11].…”

Plastic pollution is a rapidly growing environmental and human health crisis, with no sign of improvement. From 2012 to 2020, the number of studies on plastic pollution increased, and macro to nano-sized plastics have been documented in the most remote biomes of the planet. Studies have shown contamination by microplastics (MPs) in various types of food consumed by humans, including seafood, honey, sugar, salt, tap and bottled water and beer. This study’s objective was to detect the possible contamination by MPs in drinking water samples collected from two main residential and commercial areas of Brasilia. A total of 32 samples (500 mL) of tap water were collected from residential and commercial areas. Samples were processed and transferred to a Sedgewick-Rafter counting cell chamber. The presence of MP particles was analyzed using a Nikon Eclipse fluorescence microscope. MPs were found in 100% of the samples. The mean microplastic particles per 500 mL found in the South Wing area was 97 ± 55, while the mean number of particles in the North Wing area was 219 ± 158, and the MPs found ranged in size from 6–50 microns. The study results reveal a disturbing amount of MP particles in Brasilia’s tap water. This surprising number of particles in residential and commercial tap water is especially considering that tap water is not the only source of MPs to which people are exposed.

“…Boa Viagem has an important environmental educational program coordinated by city hall, called 'Praia Limpa' which means 'Clean Beach'. Despite this, the beach is also famous for severe environmental problems, such as shark attacks and contamination by plastic fragments and pellets [20][21][22][23]. Also known for its impact in Recife's landscapes, the Capibaribe River is now one of the most polluted in the country, with some stretches taken over by plastic trash.…”

“…Os MPs são definidos como partículas de plástico inferiores a 5 mm (Arthur;Baker & Bamford, 2009) e podem ser classificados como primários ou secundários, dependendo de sua fonte de origem (Barnes et al, 2009;Avio;Gorbi & Regoli, 2016). Materiais fabricados com dimensões inferiores a 5 mm, como as esférulas plásticas (pellets), utilizadas para a produção de materiais poliméricos, e as partículas de plástico, usadas em produtos de higiene pessoal (esfoliantes e pastas de dente, por exemplo), são definidos como MPs primá-Ingrid Schneider, Daiana Maffessoni rios e chegam ao ambiente marinho por derramamentos acidentais durante a sua cadeia produtiva e através de descargas de águas residuais (Ziajahromi et al, 2017;Andrady, 2017;Castro;Silva & Araújo, 2018). Já os MPs secundários resultam de objetos plásticos que se fragmentam em pedaços menores, por processos físicos e químicos de degradação, como a fotodegradação e abrasão física (Moore, 2008;Cole et al, 2011;Andrady, 2011;Ivar do Sul, 2014).…”

Este estudo analisou a presença de microplásticos no sedimento arenoso em três praias no litoral norte do Rio Grande do Sul – Sul do Brasil, com diferentes níveis de antropização. As praias de Torres e Capão da Canoa são mais urbanizadas que a Praia das Cabras (Cidreira). A amostragem foi realizada ao longo das quatro estações do ano. Em cada localidade, foram amostradas seis parcelas quadradas (0,5 x 0,5 m), incluindo três pontos na marca da preamar e três pontos na base das dunas. A presença de microplásticos foi registrada em todas as amostras. No total, foram coletados 1.727 microplásticos (886 unidades de fragmentos e 841 unidades de pellets). A Praia das Cabras apresentou maior concentração de microplásticos (1.083 unidades) do que as praias urbanizadas: Capão da Canoa (482 unidades) e Torres (162 unidades). Além disso, foi encontrada grande quantidade de pellets na Praia das Cabras, enquanto as outras duas praias apresentaram maior acúmulo de fragmentos. O maior acúmulo de microplásticos foi encontrado durante a primavera (687 unidades), seguida pelo inverno (462 unidades), verão (410 unidades) e outono (168 unidades). A presença de microplásticos em praias arenosas parece não estar relacionada somente à urbanização, mas também à interação continente-oceano.
