Microplastiche: classificazione, identificazione e rimozione all'interno degli impianti di trattamento delle acque reflue
This Italian-language paper reviews how microplastics are classified, identified using techniques like FTIR spectroscopy, and removed in wastewater treatment plants. Conventional treatment plants remove a substantial portion of microplastics but still allow many particles to pass through into the environment. The review calls for better treatment technologies and standardized methods to assess microplastic removal efficiency.
