Resumo: | The aquatic environment has suffered anthropic impacts through inadequate dumping from domestic, agricultural and industrial sources. Such waste products become fragmented into microplastics (MPs) which accumulate in these ecosystems and cause impact. This study offers the first evaluation of contamination of the surface water by MPs in the Paraíba River estuary, Paraíba State, northeast Brazil. Monthly surface water samples were performed with a phytoplankton net from March 2019 to February 2020, between Restinga Island and the Cabedelo Harbor, downstream of the estuary. About the abiotic factors tested, tide height and precipitation were inversely proportional to MPs abundance at the water surface. While water transparency, wind speed and direction and volume of filtered water did not affect it significantly. A total of 443 MPs were obtained in 1116.26 m3 of filtered water, with a mean abundance of 1.96 ± 1.44 MP/m3, ranging from 0.33 (September) to 4.76 (January). The results reveal an important incidence of MPs pollution downstream in this system. The predominance of MPs fibers (51%) and fragments (48%) result from the slow, natural breakdown of solid waste, confirming the lack of the proper discarding to trash in the João Pessoa metropolitan region. These findings underscore the need for the implementation of simple mitigating measures, such as basic sanitation to reduce local pollution as well as effective routine assessments from the anthropic impact and from water quality control measures in this and many other Brazilian estuaries. |

Los desechos se fragmentan en microplásticos (MPs) que se acumulan en estos ecosistemas y causan un impacto tan grande. Este estudio proporciona la primera evaluación de la contaminación del agua superficial por MPs en el estuario del río Paraíba, Paraíba, Brasil. Se realizaron muestreos mensuales de agua superficial con red de fitoplancton entre marzo/2019 y febrero/2020, aguas abajo en este estuario. En los factores abióticos probados, la altura de las mareas y la precipitación fueron inversamente proporcionales a la abundancia de MP en la superficie del agua. Mientras que la transparencia del agua, la velocidad y dirección del viento y el volumen de agua filtrada no afectaron significativamente dicha abundancia. Se obtuvieron un total de 443 MPs en 1116.26 m3 de agua filtrada, con una abundancia media de 1,96 ± 1,44 MP/m3, variando de 0,33 (septiembre) a 4,76 (enero). Los resultados revelan una importante incidencia de contaminación por MP aguas abajo en este sistema. El predominio de fibras (51%) y fragmentos (48%) de PM refleja la descomposición lenta y natural de los residuos sólidos, lo que confirma la falta de eliminación adecuada de basura en la región metropolitana de João Pessoa. Este estudio refuerza la necesidad de implementar medidas de mitigación simples, como saneamiento básico, para reducir la contaminación local, así como evaluaciones de impacto antrópico efectivas y de rutina destinadas a controlar la calidad del agua en este importante estuario de Paraíba.O ambiente aquático tem sofrido impactos antrópicos por meio de despejos inadequados de fontes domésticas, agrícolas e industriais.
