Researchers assessed microplastic abundance and characteristics in coral reef tissues and sediments at Penimbangan Beach, finding MPs in all 12 coral samples analyzed. Fiber and fragment types dominated, with polymers matching common fishing and packaging materials, reflecting local pollution inputs to the reef ecosystem.
Microplastics in the Coral Reef Systems from Xisha Islands of South China Sea
Researchers surveyed microplastic distribution in seawater, fish, and corals across three atolls in the Xisha Islands of the South China Sea. They found microplastics present in all sample types, with lagoons showing the highest water concentrations and fibrous rayon and polyethylene being the dominant polymer types. The findings indicate that even relatively remote coral reef systems are contaminated with microplastics, which may threaten reef health.

Microplastics as a sedimentary component in reef systems: A case study from the Java Sea
Researchers investigated microplastic distribution in sediments from two tropical atoll reef platforms in Indonesia. The study found that microplastics are a component of reef sediments, with distribution patterns influenced by reef geomorphology and hydrodynamic processes, highlighting the need to better understand how microplastics accumulate in coral reef systems and their potential impacts on reef health.
Abundance and characterization of microplastics in amphipods from the Japanese coastal environment
