Abstract

Background: Plastic debris smaller than 5 mm is categorized as microplastic, a pollutant with persistent characteristics that often contains toxic or carcinogenic compounds. These particles can infiltrate soil systems, migrate into the food chain, and ultimately threaten both environmental integrity and human health. This research focuses on identifying the types and quantifying the abundance of microplastics in soils collected from three final disposal sites in Lampung Province, Indonesia. Methodology: Sampling at three landfill points was carried out purposive sampling method, with microplastics sample analyzed through visual inspection by microscopy and polymer composition confirmed using Fourier Transform Infrared (FTIR) Spectroscopy Method. Findings: Landfill sites B1 and C1 exhibited the highest abundance of microplastics, reaching 195 particles per kilogram of soil. The particles displayed morphological diversity, including fragments, fibers, and films, with fragments representing the predominant category. The color distribution was largely transparent, black, and brown, while the detected particle sizes ranged from 2.12 to 110.25 μm. Polymer analysis revealed the presence of polyethylene (PE), polyamide, and polystyrene, alongside particles suspected to be polyethylene terephthalate (PET). These findings indicate that physical and chemical degradation processes accelerate the breakdown of plastics into smaller fragments, thereby contributing to elevated microplastic levels in landfill soils. Contribution: The outcomes of this research, derived from visual microscopy and FTIR Spectroscopy-based identification of microplastics in Lampung landfill soils, The findings offer essential data for the development of monitoring frameworks and risk assessment strategies related to soil and environmental risks in the region

Abstract

Microplastics are plastic waste that is smaller than 5 mm in size Microplastics have persistent properties and contain toxic or carcinogenic chemicals that can seep into the soil through osmosis and enter the food chain, thus impacting health and the environment. The purpose of this study is to determine the types of microplastics in the Three Final Processing Sites in Lampung Province and to determine the abundance of microplastics in the Three Final Processing Sites in Lampung Province. Soil samples were taken using purposive sampling at three different points at the landfill on December 4, 2024. visual identification and abundance of microplastics using microscope and FTIR (Fourier transform infrared) test. The highest abundance of microplastics was found at the Bumi Ayu landfill point (580 particles. Kg-1). The diversity of microplastic characteristics in the form of fragments, fibers, and films, the most fragment particles in soil samples. The color of microplastic particles is predominantly black and brown. The size range of microplastic particles found is between 2,12m-110,25m. Microplastic pollutants are Nylon, PVA, PMMA. The results of this study reveal that plastics that have undergone physical or chemical degradation can more easily become small fragments, thus increasing the number of microplastics produced.
