ClearAssessment of microplastic pollution in corals, seawater, and marine sediments in the Gulf of Thailand
Researchers assessed microplastic occurrence, abundance, and characteristics in coral, seawater, and sediment samples from two reef sites in the Gulf of Thailand, detecting microplastics in all coral samples at concentrations ranging from 0.24 to 2.60 particles per gram and finding spatial variability across reef species and sites.
Abundance of microplastics and its ecological risk assessment in coral reef regions of Peninsular Malaysia
Researchers surveyed microplastic contamination in surface waters around coral reef regions of Peninsular Malaysia. They detected microplastics at all sampling sites, with the Perhentian Islands showing significantly higher levels than Tioman Island, likely due to oceanographic differences. Small fragments and fibers of polyethylene and polypropylene were the most common types found, providing baseline data on microplastic pollution in these sensitive reef ecosystems.

Assessment of microplastics contamination in selected coral species from Kuantan coastal waters off the South China Sea
Three coral species from Malaysian coastal waters contained microplastics identified by FTIR spectroscopy, with Acropora showing the highest abundance and concentrations varying between two sampling locations, confirming coral reef ecosystems as sinks for microplastic pollution.
Occurrence And Abundance Of Microplastics In Coral Reef Sediment: A Case Study In Sekotong, Lombok-Indonesia
Microplastics were found in coral reef sediments in Sekotong, Lombok, Indonesia, with possible contributions from ocean current transport through the Indonesian Throughflow. The findings highlight that microplastic contamination has reached Indonesia's coral reef ecosystems, which are among the most biodiverse on Earth.
Plastics are a new threat to Palau’s coral reefs
Researchers detected microplastics in seawater, sediments, and beach sand around the pristine coral reef system of Palau, confirming that even remote, well-protected marine environments are not free from plastic pollution and highlighting the global reach of this contamination.
Microplastics in coral from three Mascarene Islands, Western Indian Ocean
Researchers compared microplastic concentrations, morphotypes, sizes, colors, and polymer compositions across six coral genera from three remote Mascarene Islands in the western Indian Ocean over a 1200 km transect. Microplastics were detected in all coral genera across all islands, with polymer types and concentrations reflecting both local and long-range ocean transport of plastic debris.
Reef‐building corals act as long‐term sink for microplastic
Coral reef structures were shown to act as long-term sinks for microplastics, with microplastics accumulating in reef framework interstices and sediments at higher concentrations than surrounding seawater, potentially contributing to the resolution of the missing plastic problem in ocean budgets.
Linking the Tourism Activity to the Occurrence and Distribution of Microplastics
Researchers assessed microplastic abundance, type, and spatial distribution in coastal water, sediments, and fish across three zones of Gili Trawangan, Indonesia, finding that tourism-related activities concentrated microplastics at recreational beaches with concentrations reaching 19.25 particles/L.
Occurrence and characteristics of microplastics in the coral reef, sea grass and near shore habitats of Rameswaram Island, India
Researchers compared microplastic occurrence and characteristics alongside heavy metal contaminants in water and sediment across coral reef, seagrass, and nearshore habitats of Rameswaram Island, India, finding mean concentrations ranging from 24 to 96 items/L and identifying habitat-specific differences in contamination profiles.
Distribution and biological implications of plastic pollution on the fringing reef of Mo’orea, French Polynesia
This study quantified both macro- and microplastic pollution on the coral reef of Mo'orea in French Polynesia, finding plastic at every sampled beach and in reef sediments. The research demonstrates that even remote Pacific island coral reefs receive significant plastic contamination from oceanic gyres and local sources.

Spatial distribution of microplastics around an inhabited coral island in the Maldives, Indian Ocean
Researchers investigated microplastic accumulation across fore reef, reef flat, and beach sediment environments surrounding a small inhabited coral island in the Maldives, finding 1,244 individual microplastic pieces across 22 sampling sites. The study reveals that even remote inhabited islands in the Indian Ocean show significant microplastic contamination, with spatial distribution patterns reflecting local hydrodynamics and human activities.

Microplastic pollution in tropical coral reef ecosystems from the coastal South China Sea and their impacts on corals in situ
Researchers studied microplastic contamination in coral reef ecosystems off southern China, finding plastic particles in seawater, sediment, corals, shellfish, and fish. Different coral species absorbed microplastics at different rates, with smaller particles penetrating deeper into coral tissue. Since coral reefs support fisheries and coastal communities, this contamination could affect both marine ecosystems and the seafood that people eat.
