“…Informações sobre a adsorção de substâncias tóxicas por organismos são escassas, porém, alguns estudos evidenciaram que MPs ingeridos pelos organismos translocam POPs e apontam para danos ao sistema endócrino, decréscimo nas funções de mobilidade, desenvolvimento, reprodução e sobrevivência (Chua et al 2014). Apesar disso, estudos sobre a incorporação ou excreção de poluentes por organismos de praias a partir da ingestão de MPs, incluindo ensaios ecotoxicológicos, são escassos em todo o mundo e ausentes no Brasil (Costa et al 2021). Essa carência de informação é relativamente surpreendente, já que os organismos que vivem nas praias são considerados sentinelas e potenciais biomonitores, tanto de MPs quanto de contaminantes que podem ser adsorvidos (Costa et al 2021).…”

A presença e persistência de microplásticos (MPs) no ambiente marinho causam diversos impactos ambientais, sociais e econômicos. Esta revisão identificou lacunas, avaliou o cenário atual de estudos com MPs em praias arenosas do Brasil e elencou as metodologias aplicadas para análise desse material. Em escala global, as publicações sobre MPs são datadas a partir de 1974, porém no Brasil, o primeiro artigo foi publicado em 2009. Os compartimentos da praia com maior número de estudos sobre MPs foram o sedimento (76%), seguido da água (12%) e biota (12%). Os estudos revisados evidenciam que as principais fontes de MPs são turismo, pesca e descarga de rios, enquanto a ação das ondas e ventos contribui para dispersão dessas partículas para praias menos urbanizadas. A identificação dos padrões e processos da contaminação de praias brasileiras por MPs esbarra em incongruências metodológicas, como a falta de padronização das unidades de medida e métodos de coleta. Ainda, os efeitos ecológicos da incorporação dos MPs pela biota têm sido pouco abordados na costa brasileira. Incentivamos a elaboração de protocolos de amostragem em escala nacional e avaliação dos efeitos da ingestão de MPs em diferentes níveis biológicos. Dessa forma, será possível traçar estratégias de mitigação favorecendo a conservação dos sistemas bióticos das praias arenosas.Palavras-chave: impactos; litoral brasileiro; plástico; lixo marinho; resíduo sólido. CONTAMINATION BY MICROPLASTICS ON SANDY BEACHES OF BRAZIL: A QUALITATIVE REVIEW:The presence and persistence of microplastics (MPs) in the marine environment causes several environmental, social and economic impacts. This review identified gaps, evaluated the current scenario of studies with PMs on sandy beaches in Brazil and listed the methodologies applied to analyze this material. On a global scale, publications on PMs date from 1974, but in Brazil, the first article was published in 2009. The beach compartments with the highest number of studies on PMs were sediment (76%), followed by water (12%) and biota (12%). The reviewed studies show that the main sources of PMs are tourism, fishing and river discharge, while the action of waves and winds contributes to the dispersion of these particles

“…The arrival of plastic debris in a particular habitat can ultimately affect organisms and the environment. For example, plastic debris can be embrittled and broken down into microplastics, which increases the bioavailability for the organisms in the habitat, such as ghost crabs, polychaetes, sandhoppers, and shorebirds in the intertidal area [4][5][6][7][8]. The aesthetic value will be decreased due to debris, which will affect the beach's preferability and, subsequently, the economy [9].…”

Plastics account for 60–80% of marine debris worldwide, and, in 2021, Malaysia was the 28th largest plastic polluter in the world. In light of this finding, the Malaysian government has launched the Roadmap Towards Zero Single-Use Plastics 2018–2030 and the Plastics Sustainability Roadmap 2021–2030 to reduce plastic pollution and implement a circular economy for Malaysia. A comprehensive database of the status of plastic pollution in Malaysia is needed to achieve this target. This study aims to record the presence of macro- (>2.5 cm) and mesoplastic (0.5–2.5 cm) debris at selected beaches in the northern Strait of Malacca. All study sites are publicly accessible beaches (Pulau Songsong, Teluk Aling, and Pulau Gazumbo) except Pulau Lembu, which is in a Marine Protected Area (MPA). The debris was collected from predetermined transects on the beach and categorised according to its form and economic market segments in Malaysia. Most of the macro- (53–75% of total mass) and mesoplastics (52–80% of the total number) were accumulated in the backshore area. Public beaches such as Pulau Gazumbo and Pulau Songsong recorded the highest abundance of macroplastics, with 7.32 g/m2 and 9.77 g/m2, respectively. Teluk Aling recorded the lowest abundance of macroplastics (3.58 g/m2) but the highest in mesoplastics (0.55 items/m2). Most of the macroplastics found were packaging plastics such as plastic bottles, containers, and polystyrene foam debris. Although Pulau Lembu is an MPA, the amount of macroplastics found was considerably high (7.17 g/m2). Based on the beach cleanliness index, Pulau Gazumbo (−3.99) was the dirtiest site, followed by Pulau Lembu (−2.92) and Pulau Songsong (−2.85), while Teluk Aling (−1.63) was the cleanest site, which can explain the amount of macroplastic debris found. However, all the study sites’ cleanliness may not be ideal, as the indexes were less than zero due to the low availability of waste bins and insufficient frequency of beach cleaning. This may not be able to curb the effects of high anthropogenic activities conducted in addition to uncontrollable natural factors.

“…as a neutralizer of the aquatic environment by breaking down organic matters that enter the bottom of the waters into a food source so that the nutritional conditions of the waters become stable (Alavaisha et al 2019). Changes strongly influence the macrozoobenthic composition, abundance, diversity, water quality, and the substrate where they live so that macrozoobenthos is also commonly used as biological water quality indicator (Kadim et al 2013;Laini et al 2018;Harahap et al 2018;Herawati et al 2020;Kefford et al 2020;Lestari and Rahmanto 2020;Sulaeman et al 2020;Baryshev 2021;Costa et al 2021;Ndale et al 2021;Prajoko et al 2021;Sueb et al 2021).…”

Abstract. Kadim MK, Pasisingi N, Alinti ER, Alinti ER, Panigoro C. 2022. Biodiversity and community assemblages of freshwater and marine macrozoobenthos in Gorontalo Waters, Indonesia. Biodiversitas 23: 637-647. Macrozoobenthos plays an essential role in the aquatic ecosystem including as primary consumers, food sources, and water quality bioindicators. This study aimed to determine the composition, taxa abundance, community structure of the macrozoobenthos in the lower reach, estuary, and marine areas along Gorontalo waters, also their association with water quality parameters. Biota samples were collected purposively from 33 sampling points. The sampling process was conducted in June 2020 and May 2021. Macrozoobenthos samples were taken using Ekman Grab and prepared with filters (mesh size of 500 µm). Statistically, a t-test was done to assess the significance of taxa abundance difference among three different ecosystems from both sampling periods. Similarity percentages were displayed through a dendrogram. Furthermore, the biota assemblages and water quality parameters association were interpreted through Eigenvalues of Principal Component Analysis using Minitab ver. 14.0. The results showed that the macrozoobenthic community structure composed 70 taxa belonging to six classes dominated by Gastropoda, followed by Bivalvia, Malacostraca, Clitellata, Polychaeta, and Polyplacophora. The marine area had the highest abundance of macrozoobenthos (469.5 ind. m-3 in 2020; 460.9 ind. m-3 in 2021), followed by the river station (335.3 ind. m-3 in 2020; 2621 ind. m-3 in 2021), and estuary zone (217.3 ind in 2020. m-3; 848.5 ind. m-3 in 2021). The most abundant species in the lower reach area was Melanoides sp. (135.5 ind. m-3 in 2020; and 1222.5 ind. m-3 in 2021), while in the estuary was Brachidontes sp. (70.7 ind. m-3 in 2020; and 248 ind. m-3 in 2021). Batillaria sp. (128.3 ind. m-3 in 2020) and Anachis sp. (1510.7 ind. m-3 in 2021) were the species with the highest number in the marine zone. Based on the diversity and evenness index, the sea was in the medium category with no dominant species in the marine area. Biota communities in the lower reach station tend to be more like estuary biota than marine biota.
