“…This indicates that the saltmarsh interior was more efficient at trapping largesized plastic debris than microplastics. A similar phenomenon was found for intertidal mangrove wetland, which is considered an important coastal ecosystem for trapping plastic debris (Nor and Obbard, 2014;Li et al, 2018). The marine plastic debris trapped in the mangroves was considered to degrade into microplastics (Nor and Obbard, 2014).…”

“…The marine plastic debris trapped in the mangroves was considered to degrade into microplastics (Nor and Obbard, 2014). However, the amount of microplastics in sediments under mangroves was significantly lower than the adjacent area immediately outside of the mangroves (Li et al, 2018), implying a removal mechanism for microplastics in mangroves.…”

“…Nor and Obbard [25] reported averages of 12 to 63 MPs/kg in mangroves of Singapore while Zhang et al [59] reported MP averages ranging from 273 to 3520 MPs/kg in mangroves further away from the city and mangroves closer to industrial/urban zones, respectively, in China. Based on these and other recent reports (e.g., [28,30,60]), South African mangroves can, therefore, be considered moderately (e.g., St. Lucia) to highly (e.g., Isipingo) polluted by MPs compared with other parts of the world. This is concerning when one considers that South Africa is a developing country with high population growth [61], limited consumer and environmental awareness, and multiple waste management inadequacies [62].…”

“…Unfortunately, they can also trap considerable loads of plastic litter [23]. Plastic retention in mangrove forests remains largely unexplored, with only a handful of studies globally having investigated this phenomenon (e.g., [23][24][25][26][27][28][29][30]). do Sul et al [27], for example, tagged and released macroplastics in Brazilian mangroves and found that more than half of the tagged plastics were still present in the forest by the end of the experiment, demonstrating the ability of mangroves to retain plastic for long periods.…”

Plastic and, particularly, microplastic (MP) pollution is a growing research theme, dedicated largely to marine systems. Occurring at the land–sea interface, estuarine habitats such as mangroves are at risk of plastic pollution. This study compared MP pollution (level, morphotype, polymer composition, size and colour) across four South African estuaries, in relation to the built and natural environment. Mouth status, surrounding human population densities and land-use practices influenced the level and type of MP pollution. Systems that were most at risk were predominantly open estuaries surrounded by high population densities and diverse land use types. Microplastic levels and the diversity of types detected increased with increasing levels of anthropogenic disturbance. Overall, microfibres dominated in estuarine water (69%) and mangrove sediment (51%). Polyethylene (43%) and polypropylene (23%) were the dominant polymers overall. Weathered fishing gear, weathered packaging items and run-off from urban/industrial centres are probable sources of MP pollution . Increased run-off and river input during the wet/rainy season may explain the markedly higher MP loads in estuarine waters relative to the dry season. By contrast, MP deposition in mangrove sediment was higher during the dry season. Sediment MP abundance was significantly positively correlated with both pneumatophore density and sediment size (500–2000 µm). This study highlights the role of mangroves as MP sinks, which may limit movement of MPs into adjacent environments. However, under conditions such as flooding and extreme wave action, mangroves may shift from sinks to sources of plastic pollution.

“…Aunque actualmente se ha avanzado en el conocimiento sobre la distribución y abundancia de la basura marina (ver mapa de distribución en https://litterbase.awi.de/litter), aún existen importantes vacíos en el conocimiento sobre los impactos y efectos de los microplásticos en los ecosistemas y en la salud humana (Horton et al 2017;Troost et al 2018;Rainieri & Barranco, 2019;Novotna et al 2019;Prata et al 2019a). A pesar de los reconocidos impactos de la basura, y de los microplásticos en específico, hay pocos estudios disponibles a nivel global en los ecosistemas de manglar (Cordero & Costa, 2010;Debrot et al 2013;Mohamed & Obbard, 2014;Naji et al 2017;Li et al 2018;Martin et al 2019;Garcés-Ordóñez et al 2019).…”

La basura en el mar está generando impactos negativos en los ecosistemas marinos y comunidades humanas, razón por la cual se considera un problema relevante cuya solución ha sido incluida como meta dentro del Objetivo de desarrollo sostenible n.o 14. El propósito de este estudio fue identificar y valorar los impactos negativos de la contaminación por basura marina en el ecosistema de manglar de la Ciénaga Grande de Santa Marta (CGSM), Caribe colombiano. Los impactos se identificaron mediante observación in situ (impactos observados), durante salidas de campo realizadas en febrero de 2018 y a partir de la revisión de información secundaria (impactos potenciales). La valoración de la importancia ambiental de los impactos observados se realizó tomando como base la metodología propuesta por Fernández (2010), que considera los criterios de intensidad, extensión, momento, reversibilidad, recuperabilidad, sinergia y acumulación. En total, se identificaron 10 impactos observados en campo y 11 impactos potenciales causados por la basura marina en los manglares de la CGSM. La presencia, la acumulación y la degradación de la basura marina generan impactos moderados, severos y críticos en el manglar de la CGSM. De estos se resaltan, por el peligro potencial, la acumulación de microplásticos en el ambiente, la limitación del establecimiento de propágulos y crecimiento de plántulas, y los cambios físicos en el suelo. Estos resultados servirán para que las autoridades ambientales puedan tomar acciones preventivas y reductivas de este tipo de contaminación y contribuir, significativamente, a la recuperación del manglar y sus servicios ambientales.
