Resumo: | The study aims to determine the current spatial distribution of plastic pellets on Santos beach, both along the longitudinal axis of the beach and along the tidal lines, and to assess the amount of entry of this material. To determine the spatial distribution of plastic pellets, 108 sample elements were collected with a square area of 1.0 m on side removed from the sediment with a depth of 10 cm, totaling 0.1 m3. Sampling took place in the summer of 2020, from 01/08 to 03/21. 11,979 pellets were collected. Relatively to the sample beach areas, the wrack line zone presented the highest numerical densities in sections 9 and 8, with averages of 742.000±237.765 pellets/0.1 m³ and 617.333±77,242 pellets/0.1 m³, respectively. Regarding the longitudinal axis of the beach, pellets were found in abundance in section 5, located in the central region of the beach, which is influenced by hydrodynamics and marine currents, where the highest numerical density was observed in the dry zone with an average of 188.667±127.563 pellets/0.1 m³ and an average of 584.000±343.167 pellets/0.1 m³ in wrack line zone. When analyzing the numerical density of pellets inlet, section 9 had highest average in wrack line zone, which receives the deposit of material brought by marine currents, near the entrance to the Port of Santos where takes place the active transport of these microplastics. The results indicate that the pellet depositional zone occurs between channels 3 and 4 and at Ponta da Praia. |

Para determinar la distribución espacial de los gránulos plásticos, se recolectaron 108 elementos de muestra con un área cuadrada de 1,0 m en el lado removido del sedimento con una profundidad de 10 cm, totalizando 0,1 m³. El muestreo se realizó en el verano de 2020, del 08/01 al 21/03, y se recolectaron 11.979 gránulos. En relación a las áreas de playa muestreadas, la zona “línea de señal” presentó las densidades numéricas más altas en las secciones 9 y 8, con promedios de 742,000 ± 237,765 pellets / 0,1 m³ y 617,333 ± 77,242 pellets / 0.1 m³, respectivamente. En cuanto al eje longitudinal de la playa, se encontraron abundantes pellets en el tramo 5, ubicado en la región central de la playa, el cual está influenciado por la hidrodinámica y las corrientes marinas, donde se observó la mayor densidad numérica en la zona seca con un promedio de 188,667 ± 127,563 pellets / 0,1 m³ y un promedio de 584,000 ± 343,167 pellets / 0,1 m³ en la zona de “línea de señal”. Al analizar la densidad numérica de entrada de pellets, el tramo 9 tuvo el promedio más alto en la zona de "línea de señal", que recibe el depósito de material traído por corrientes marinas, cerca de la entrada al Puerto de Santos donde se lleva el transporte activo de estos microplásticos. Los resultados indican que la zona de depósito de pellets se produce entre los canales 3 y 4 y en Ponta da Praia.O estudo objetiva determinar a atual distribuição espacial de pellets plásticos na praia de Santos, tanto ao longo do eixo longitudinal da praia como ao longo das linhas das marés e avaliar a quantidade da entrada desse material.

A amostragem ocorreu no verão de 2020, entre os dias 08/01 a 21/03, e foram coletados 11.979 pellets. Relativamente às zonas de praia amostradas, a zona “linha do deixa” apresentou as maiores densidades numéricas nos trechos 9 e 8, com médias de 742,000±237,765 pellets/0,1 m³ e 617,333±77,242 pellets/0,1 m³, respectivamente. Com relação ao eixo longitudinal da praia, os pellets foram encontrados em abundância no trecho 5, situado na região central da praia que é influenciada pela hidrodinâmica e pelas correntes marinhas, onde observou-se a maior densidade numérica na zona seca com média de 188,667±127,563 pellets/0,1 m³ e ainda uma média de 584,000±343,167 pellets/0,1 m³ na zona “linha do deixa”. Ao analisar a densidade numérica de entrada de pellets, o trecho 9 apresentou a maior média na zona “linha do deixa”, que recebe o depósito de material trazido pelas correntes marinhas, próximo à entrada do Porto de Santos onde acontece o transporte ativo destes microplásticos.
