Abundance and Characteristics of Microplastics in Surface Waters of Banten Bay, Serang, Indonesia
Summary
Researchers measured microplastic concentrations in surface waters of Banten Bay, Indonesia, across five sampling sites representing different human activities. They found concentrations ranging from 0.12 to 1.03 particles per liter, with fragments and fibers being the most common types, primarily made of polypropylene and polyethylene. The study links microplastic prevalence to domestic waste and human activities in the surrounding area.
Microplastics are plastic particles measuring less than 5mm in size. Microplastics that infiltrate the environment accumulate in aquatic systems and are challenging to eradicate due to their persistent properties. The activity and source of other pollutants significantly influence the prevalence of microplastics in aquatic environment. This study aimed to determine the frequency and classification of microplastics in Banten Bay’s waters. Sampling was performed at five sites selected to represent diverse activities in the surrounding area of the waters. The concentration of microplastic particles observed at five sampling sites in Banten Bay ranged from 0.12 to 1.029 particles/L. The discovered microplastics comprised fragments, fibers, and films. The most commonly identified types of microplastics were fragments (52.645%) and fibers (41.79%), followed by films (5.56%). The prevalence of these two categories is mostly affected by domestic wastes and human activities. Microplastics measuring between 500 and 1000µm are commonly identified at the five specified monitoring locations in the Banten Bay area. The primary microplastics discovered were blue, black and transparent in color. Polypropylene (38%), propylene (25%), and polyethylene (22%) are the predominant materials across the five sampling sites. These findings highlight the widespread presence of microplastics in Banten Bay and emphasize the need for improved waste management and pollution control to mitigate further contamination. The dominance of fragments and fibers suggests ongoing degradation of larger plastics and direct input from domestic sources. Regular monitoring and public awareness are crucial in managing microplastic pollution in coastal waters. Future research should focus on the ecological impact of these particles on marine organisms and the food chain.
