Application of multi-step approach for comprehensive identification of microplastic particles in diverse sediment samples

The tremendous increase of plastic production, its intensive usage in packaging, as transport material, and the insufficient management of plastic garbage have led to a rise in microplastic particles as an anthropogenic contaminant in our environment. To develop appropriate management and remediatio...
