Identification of Microplastic Type and Abundance in East Coast of Karimun Besar Island, Riau Islands
AI summary Read the abstract
Researchers surveyed the types and abundance of microplastics along the east coast of Karimun Besar Island in Indonesia's Riau Islands Province. High anthropogenic activity in the area was associated with microplastic contamination in coastal waters and sediments.
High anthropogenic activities on the east coast of Karimun Besar Island contribute a certain amount of wastes, especially plastics. Plastics will be degraded due to the natural mechanism of smaller parts and known as microplastics. Small size and widespread distribution has caused microplastics can be found widely in the ocean and coastal areas. This study was conducted in March 2020, located on the east coast of Karimun Besar Island, Province of Riau Islands. The purpose of this study was to know the presence of microplastics in its coastal water. The method used in this study was a survey method by taking samples from four stations with suspected different anthropogenic activities. The results showed that the lowest abundance of microplastics in the coastal waters of the east coast of Karimun Besar Island was 63,33 particles/m3 and the highest was 161,66 particles/m3, with the dominant type found was fibre. The abundance of the microplastic between station was found to be significantly different (p < 0,05)

AI summary Read the abstract
Researchers surveyed microplastic contamination in sediments in the Selat Panjang waters of Indonesia and found that fragment-shaped microplastics were the most common type, followed by films and fibers. Microplastic abundance varied significantly across the three sampling stations, with the highest concentrations found near a port area.
