Microplastics are small pieces of plastic waste (less than 5 mm), which are found along the coast, the sea level and the bedding. The present study examines the frequency, distribution, and forms of microplastics in bivalve tissues and sediments sampled on the coast of Bandar Lengeh. Microplastic separation was performed by spectral density and spectrophotometric (FT-IR) and (SEM-ED) methods for polymer detection. The microplastics found were varied colors including black, white, transparent, red, pink and green. Using the obtained data, at the Lengeh port stations, the average total number of extracted microplasms per shell was 3.93 and the number of microplastics in Bandar-Lengeh sediments was 34.5 ± 0.17. The most commonly found polymers were polyethylene (PE), polyethylene terephthalate (PET) and nylon. The most abundant type of micro-plastics isolated from Pinctada radiata, microfibers and fragments were extracted from fiber and film sediments. The present study can provide useful information for further research as well as forensic monitoring and monitoring of this contaminant in the Persian Gulf marine environment.
