Microplastic Abundance in Sediment in Pangandaran Waters, West Java, Indonesia
Summary
This study measured microplastic abundance in sediments across Pangandaran waters, finding highest concentrations of fibers and fragments near tourism-affected coastal zones and identifying particle size (106–250 µm) as the dominant fraction retained in sediments. Oceanographic factors including waves, tides, and currents were identified as the primary mechanisms controlling microplastic distribution across the sampling sites.
Rapid development in the tourism sector of Pangandaraan raises various problems such as environmental degradation, environmental pollution and waste problems. Microplastic pollution in the oceans is a type of hazardous waste, with microscopic plastic particles less than 5 mm in size. Generally, easy-to-find microplastics include fragments, films, and fibers. Microplastic abundances are found in deep sea areas similar to those in the intertidal area. The purpose of this research is to know the microplastic composition which is sedimentation in various types of sediments and the factors that influence the changes to the microplastic sedimentation in the Pangandaran waters. This research uses the survey method. The most common microplastic particles in station 2 were 12.622 particles (fibers and fragments) and the lowest was found in station 4 of 1.809 particles (fiber, fragment and film). The highest number of microplastic particles trapped in mesh size sediment between 106 µm – 250 µm. Current, waves and tides are factors that cause microplastic movement in the sea. The distribution of microplastic particles is influenced by oceanography factor, density, shape and size of microplastic.
