ClearCharacteristics of Microplastic in Selected Marine Sponges from Pasir Putih Situbondo, East Java, Indonesia
Microplastics were characterized in marine sponges collected from a specific ocean region, finding plastic particles of diverse polymer types embedded in sponge tissue. Marine sponges, as filter feeders, accumulate microplastics from surrounding water and may serve as useful bioindicators of ocean plastic contamination.
Interaction Mechanisms Between Marine Sponges (Porifera) and Microplastics: A Bioecological Overview
This systematic review looks at how marine sponges — natural filter feeders — accidentally take in microplastics along with their food. The research shows sponges can accumulate significant amounts of tiny plastic particles, which may affect their health and the broader reef ecosystem. Since sponges play an important role in ocean nutrient cycling, their contamination with microplastics signals wider pollution concerns for marine food webs.
Measuring the Effects of Microplastics on Sponges
Researchers investigated how microplastics affect marine sponges, which are important filter feeders in coastal ecosystems, noting that very little research had examined sponge-microplastic interactions. The study aimed to fill a knowledge gap about microplastic impacts on a key group of benthic organisms that filter large volumes of seawater.

Seagrass sponge (Agelas conifera: Demospongia) potential of microplastic accumulation from Pramuka Island, Seribu Islands
Marine sponges collected from a tourist island near Jakarta accumulated 167-300 microplastic particles per gram of tissue, considerably more than were found in surrounding water or sediment. The findings show sponges can concentrate microplastics from their environment, making them useful biological indicators of pollution.
Sponges as bioindicators for microparticulate pollutants?
This study investigated whether sponges can serve as bioindicators of microparticle pollution in coral reef environments, finding that sponges incorporate foreign particles including microplastics from the surrounding water. Sponges could be useful sentinel organisms for monitoring microplastic contamination in reef ecosystems given their extensive filter feeding.
Interaction Mechanisms Between Marine Sponges (Porifera) and Microplastics: A Bioecological Overview
This systematic review summarizes how marine sponges, which are natural filter feeders, interact with microplastic particles in the ocean. The research shows that sponges unintentionally take in microplastics along with their food, which can cause cellular stress and may affect their ability to filter ocean water, with broader consequences for marine ecosystem health.
Plastics in Porifera: The occurrence of potential microplastics in marine sponges and seawater from Bocas del Toro, Panamá
Researchers found potential microplastics in the tissues of six Caribbean sponge species from Bocas del Toro, Panama, with concentrations ranging from 6 to 169 particles per gram of dry tissue and an average of 107 particles per liter in surrounding seawater.
Determination of Microplastic Compounds in Some Species of Freshwater Snails in Brantas River, East Java, Indonesia
This study examined microplastic contamination in three freshwater gastropod species from Indonesia's Brantas River system, documenting MP abundance and polymer types across sampling sites and species to assess contamination patterns in edible freshwater snails consumed locally.
Characterization of microplastics in the waters of the Santos Basin and the Ilha Grande Bay, and in marine sponges of the species Dragmacidon reticulatum (Ridley & Dendy, 1886)
This study characterized microplastics in coastal waters of two Brazilian bays and in the marine sponge Dragmacidon reticulatum. Microplastics were found in both water samples and sponge tissue, demonstrating that filter-feeding invertebrates accumulate plastic particles from their surroundings.
Fate of microplastic captured in the marine demosponge Halichondria panicea
Researchers tracked the fate of 2 and 10 micrometer plastic beads in the marine sponge Halichondria panicea, comparing their retention with that of edible bacteria and algal cells, finding that sponges retained plastic particles differently from food particles. The study advances understanding of sponges as microplastic monitoring organisms by revealing how plastic particles are processed within sponge tissues.
Microplastic distribution in urban vs pristine mangroves: Using marine sponges as bioindicators of environmental pollution
Researchers collected marine sponges from urban and pristine mangrove environments and measured microplastic content, finding significantly higher MP loads in urban sponges and demonstrating that sessile benthic sponges can serve as effective bioindicators of coastal microplastic pollution.
Microplastic filtering and its physiological effects on the Mediterranean bath sponge Spongia officinalis (Porifera, Demospongiae)
Researchers tested how the Mediterranean bath sponge filters and responds to microplastic particles in seawater. They found that these sponges are highly efficient at capturing microplastics in the 1-5 micrometer size range but showed signs of physiological stress including changes in respiration and cellular damage. The findings suggest that filter-feeding marine organisms like sponges are both exposed to and affected by microplastic contamination.
Occurrence of microplastics in freshwater gastropods from a tropical river U-Taphao, southern Thailand
This study found microplastics in freshwater gastropod snails from a tropical river in southern Thailand, with concentrations ranging from about 4 to 7 particles per individual depending on species and collection site, confirming microplastic ingestion in freshwater invertebrates in Southeast Asia.
Microplastics (≤ 10 μm) bioaccumulation in marine sponges along the Moroccan Mediterranean coast: Insights into species-specific distribution and potential bioindication
Researchers found that marine sponges along the Moroccan Mediterranean coast bioaccumulate small microplastics (10 micrometers or less), with species-specific differences in accumulation patterns, suggesting certain sponge species could serve as bioindicators for microplastic pollution monitoring.
Levels of Microplastics in Aquatic Ecosystem Components of the Kedung Ombo Reservoir, Central Java: Analysis of Water, Tilapia (Oreochromis mossambicus), Sediment, Macroalgae, and Gastropods

MPs were found across all five matrices, with fibers predominating and higher concentrations in sediment and biological samples near human settlements.
Sponges as libraries: Increase in microplastics in Cinachyrella alloclada after 36 years
Researchers compared microplastic concentrations in the tropical sponge Cinachyrella alloclada using museum specimens from 1981 versus field-collected specimens from 2017, finding a tenfold increase from 0.13 to 1.37 microplastics per gram of tissue and an increase in prevalence from 10% to 80% of individuals, with Raman spectroscopy identifying polypropylene fibers as the dominant polymer type.
Microplastics in marine sponges (Porifera) along a highly urbanized estuarine gradient in Santos, Brazil
Researchers assessed microplastic contamination in marine sponges along an urbanization gradient in the Santos Estuary, Brazil. They found a 14-fold difference in microplastic concentrations between the most and least contaminated sites, with contamination patterns following the same gradient seen in molluscs from the same area. The findings suggest that marine sponges could serve as useful sentinel organisms for monitoring microplastic pollution in coastal environments.

Analysis of Microplastic Contamination on Water and Sediment in the Brantas Subwatershed of the Malang Area
This Indonesian study (published in Bahasa Indonesia) analyzed microplastic contamination in both water and sediment of the Brantas River sub-watershed in the Malang area, one of the most important river systems in East Java. Microplastics were found in both water and sediment samples across sampling locations, with fibers being a dominant form. The Brantas River supports millions of people for drinking water and irrigation, making evidence of microplastic contamination in this system a significant public health and environmental concern.
