Summary

This study measured microplastic contamination in water and sediment along the Haraz River estuary in Iran, documenting the types, shapes, and polymer compositions of particles present. The data provide a baseline for understanding plastic pollution in Iranian river systems.

Study Type Environmental

The type and extent of microplastic contamination in water and sediment of Haraz River were evaluated. Water and sediment samples were collected using a planktonic trawl with a mesh size of 300 µ and a Van Veen grab, from February to May 2017. The morphology and elemental compounds of microplastic particles were analysed using SEM/EDX. Moreover, differential scanning calorimetry (DSC) was done for polymers identification; so that the data could be used for comparative analyses. The number of pieces per kg dry weight in sediments and per cubic meter sampled water was determined. Last but not least, plastic types were also distinguished.
