The presence of microplastics in tidal sediments is a growing ecotoxicological concern for sea and benthic health. This investigation was designed to record characterize the vertical prevalence (MPs) intertidal Persian Gulf (around Bushehr city, Iran). Sediments three depths (0-10 cm, 10-20 20-30 cm) were sampled during low tide six sites along coastal zone Bushehr, Iran. MP particles found all evaluated areas sediment depths. average abundance MPs samples 117.96 ± 97.75 kg−1 dry sediment. No differences number among sites. most dominant surface 2-5 mm size. In areas, fibers fragments more abundant. Particles higher often colorless (white, transparent). Raman spectroscopy indicated polystyrene, polyethylene, polyvinyl chloride, polyethylene terephthalate, polypropylene samples. Further research required evaluate possible interaction between layers sediments. Waste management proper wastewater disposal are critical control pollution ecosystems around cities.
