Marine Debris Accumulation on the Beach in Libong, a Small Island in Andaman Sea, Thailand
AI summary Read the abstract
Researchers cataloged marine debris on beaches of Libong Island, Thailand, collecting samples over four months in 2019. Ceramic and glass debris were most abundant, followed by plastic, with fishing activities and ocean currents identified as the primary sources rather than the island's own population.
Marine debris is a global issue and a hot topic in Thailand. This study involved collecting and quantifying various types of debris at Libong Island. The study area is Libong Island, a small Island in Andaman Sea, with high biodiversity and an important source of sea grass providing a significant and vital habitat for endangered dugongs. Debris was collected on sandy beach and mud beach areas between May and August 2019. The results indicated that the ceramic and glass debris was found in the greatest number followed by plastic and other debris, thin plastic and hard plastic. The major contributing factor for the debris abundance in Libong beach was the shoreline and recreational activities which showed that the landbased sources provided major inputs of plastic pollution at the beaches. The calculation of the Clean Coastal Index (CCI) of Libong Island yielded a result of 5.8 at the sandy beach whereas at the mud beach was 0.65. Thus, the sandy beach was classified as moderately clean and the mud beach was classified as very clean.

Researchers surveyed microplastic contamination in beach and mudflat sediments at Libong Island, a relatively pristine site in Thailand's Andaman Sea. Despite the island's protected status, microplastics were found throughout, with fibers making up 59% of detected particles, showing that plastic pollution reaches even remote coastal ecosystems.

AI summary Read the abstract
Researchers conducted the first basin-scale survey of macro-litter in seagrass meadows of the Andaman and Nicobar Islands, recording 4,257 items with plastics accounting for 88% of the assemblage; high plastic loads even at remote islands indicated long-range ocean transport, while abandoned fishing gear posed substantial entanglement risk to dugongs and sea turtles.
