Abundance, distribution and correlation of microplastics in Tuapejat coastal water Mentawai Islands Indonesia
AI summary Read the abstract
Researchers found microplastics — primarily fibers, fragments, and films — in both water and sediment samples from coastal waters of the Mentawai Islands, Indonesia, with the highest concentrations linked to anthropogenic activities in this marine tourism hub.
Tuapejat is the capital city of the Mentawai Islands Regency which is located in North Sipora District, Indonesia. Beside as being the most populous city, Tuapejat is also the center of marine tourism and various activities such as urbanization, restaurants, hotels and trade. Those anthropogenic activities have the potential to provide input of plastics waste into the oceans which eventually degrades into microplastics, which then may pose a major threat to both biota and humans. This study aims to determine and quantify the microplastics content in water and sediment in these coastal waters which was conducted in August 2022. Sampling was carried out at three stations and the results of the study showed that the types of microplastics found were fibers, fragments and films. The highest total microplastics abundance was in commercial port area, whilst the lowest was found around fishing port in both seawater and sediment, respectively. The abundance of microplastics in seawater and sediments between stations in Tuapejat coastal waters was significantly different (p<0.05), and there was a positive relationship between the abundance of microplastics in seawater and in sediments. The differences between stations and the relationships that occur are discussed by looking at the influence of water quality parameters and anthropogenic activities around the sampling locations.

This Indonesian study measured microplastic abundance in the waters around Temajo Island in West Kalimantan, finding widespread contamination from fibers, fragments, and films. The results contribute to mapping microplastic pollution across Indonesian coastal ecosystems, which are under pressure from both land-based and marine plastic sources.
Microplastic Observations in the Waters of Labuan Bajo-Gili Trawangan, Indonesia
AI summary Read the abstract
Researchers collected surface water microplastic samples along the Nusa Tenggara route in Indonesia during a research expedition, finding microplastics near both populated areas and remote islands. The data show that microplastic pollution is widespread across Indonesian waters, including near the tourist destination of Labuan Bajo.
Characteristics and pollution load index of microplastics in surface coastal waters of Makassar, Indonesia
AI summary Read the abstract
Researchers found tiny plastic particles (mostly thin fibers) in every coastal water sample they tested near Makassar, Indonesia, with pollution levels highest near a busy harbor, a sign that human activity is a major source. Since these coastal waters support local seafood and fishing communities, and microplastics can move up the food chain into the fish people eat, this study offers an important baseline for tracking and eventually reducing plastic contamination in the region.
