microplastic pollution evaluation in sediments of south caspian sea (mazandaran province, iran)

Abstract: microplastics have been identified as an emerging pollutant in marine environments and can have serious impacts on the marine environment and coastal ecosystems. an important aspect of microplastics is that they threaten aquatic life and, on the other hand, are eaten by aquatic animals and then enter the food chain. in this study, marine sediments were evaluated as a sample of microplastic contamination on the south coast, sea and caspian. microplastics were observed in various colors of blue, white, red, black, etc. dimensions of microplastics collected during this study; it varied from 275.760 μm to 81171.063 μm. to determine the polymer composition of the microplastics removed from the sediment, a fourier transform infrared spectroscopy equipped with a generalized attenuation system or raman spectrometer was used. also, spss software was used to analyze all data.
