Distribution, Abundance, and Composition of Microplastics In Sediments Along the Persian Gulf Coast In 2024: A Case Study of The Genaveh, Deylam, and Imam Hassan Ports

The increasing industrial activities have led to significant microplastic pollution, particularly in coastal regions, where human and industrial activities contribute to accumulating these pollutants. This study investigates the distribution and frequency of microplastics in beach sands along the Persian Gulf coastline in Bushehr, Iran, focusing on three key ports: Genaveh, Deylam, and Imam Hassan. Microplastics were extracted using density separation methods, and their types were identified via FTIR analysis. Results showed a higher concentration of microplastics in Genaveh and Deylam ports, with fibers being the most predominant microplastic type, likely due to textile production, fishing activities, and urban wastewater discharge. Polypropylene and polyethylene were the most common plastics found, highlighting the role of consumer products and industrial waste in pollution. The study emphasizes the impact of human activities on microplastic pollution and suggests that controlling plastic waste and improving waste management strategies are crucial for mitigating environmental and health risks. These findings contribute to global efforts to understand and manage microplastic contamination in marine ecosystems.
