Determination of microplastics in Rice beetle, sitophilus oryzae (coleoptera: curculionidae)

This study was done to identify the presence of microplastics in rice beetles and they are a major problem for the environment and human health in many different ecosystems. The purpose of this study is to clarify if rice beetles, a common bug linked to stored grains and a possible sign of food contamination, contain microplastics. A comprehensive process for collecting and processing samples is part of the study approach. Rice beetle samples was collected from local rice and stored in glass containers. During the dissection procedure, special attention was taken to avoid external contamination. Advanced analytical methods which is Fourier-transform infrared spectroscopy (FTIR) was used to detect and quantify microplastics. According to this study, rice beetles consume microplastics in their surroundings, such as contaminated grain surfaces or packaging materials. Microplastics enter the human food chain due to consumption such as plastic packaging, endangering consumers' health. The types of microplastics found in the beetles were identified by this study as polymethylpentene (PMP), ethylene-acrylic acid copolymer (EAA), styrene butadiene copolymer (SBC), and ethylene propylene diene monomer (EPDM). Given the widespread usage of these polymers in packing materials, the materials and storage methods utilised in grain storage facilities are directly related to the source of contamination. This study highlights the need for better storage procedures and strategies to lower contamination by detecting the presence of microplastics in grains that have been kept. Maintaining microplastic pollution-free storage facilities can improve food supply safety and quality while safeguarding consumer health.
