Microplastic Bioaccumulation by Tiger Snail (Babylonia spirata): Application of Nuclear Technique Capability using Polystyrene Labelled with Radiotracer 65Zn

Plastic waste is a solid that difficult to decompose but can turn into environmental microplastics. Microplastics are sizes between 0.1 μm–5 mm, highly prolific anthropogenic pollutants affecting terrestrial, freshwater, and marine ecosystems. The purpose of this study was determine the ability Babylonia spirata accumulate eliminate polystyrene This experiment uses nuclear applications technique. consists two methods: manufacturing microplastics biokinetics. manufacture labeled Zn-65 based on reaction sulfonate with zinc form Zn resin. microplastic very stable in aquatic environment, so it used for bioaccumulation experiments. Biokinetics includes acclimatization/adaptation organism seven days, accumulating depuration days were placing water free contamination biokinetics calculations include BCF (Biocontration Factor), ku (uptake constant), ke (depuration constants), t1/2 (half-life). experimental results show bioaccumulate from seawater (BCF) 79.2 304.31 ml.g-1. affected by content water. biological half-life 14.54 41.78 d.
