Microplastics (MPs) are a highly pervasive environmental pollutant found in all components of our ecosystem: water, soil, and air.

Le microplastiche (MPs) sono un inquinante ambientale altamente pervasivo presente in tutti i componenti del nostro ecosistema: acqua, suolo e aria. Le MPs sono ampiamente distribuite negli ambienti acquatici e minacciano la salute degli animali, in particolare la salute umana. Le acque reflue negli impianti di trattamento vengono sottoposte a trattamenti che sollevano interrogativi sullo scarico di questi inquinanti dalle strutture. Il progetto si concentra sullo sviluppo di un innovativo filtro industriale brevettato in grado di salvaguardare non solo l'ambiente ma anche la salute, puntando a ridurre l'inquinamento da questi microcontaminanti. I campioni di acque reflue sono stati analizzati sia all'ingresso che all'uscita degli impianti di trattamento delle acque reflue (WWTP) nella Sicilia orientale per determinare la concentrazione di MPs maggiore e minore di 10 μm sia in ingresso che in uscita. Il prototipo del filtro è stato progettato per essere implementato all'uscita degli impianti di depurazione per trattenere le MP inferiori a 10 μm, le più abbondanti ma anche le più dannose per la salute umana e ambientale. Sono stati condotti studi tossicologici per analizzare gli effetti tossici delle MPs sui mitili prima e dopo l'uso del prototipo di filtro, che mira a catturare le particelle di MPs prima che possano essere rilasciate nell'ambiente, mostrando una tossicità ridotta con l'uso del filtro. Il progetto è ambizioso e ha consentito lo sviluppo di una nuova tecnologia per combattere l'inquinamento ambientale da MPs, un argomento ampiamente dibattuto negli ultimi anni a causa del continuo degrado ambientale causato dalle attività umane.

Abstract
Microplastics (MPs) are a highly pervasive environmental pollutant found in all components of our ecosystem: water, soil, and air. MPs are widely distributed in aquatic environments and threaten animal health, particularly human health. Wastewaters in treatment plants undergo treatments that raise questions about the discharge of these pollutants from the facilities. The project focuses on the development of an innovative patented industrial filter capable of safeguarding not only the environment but also health, aiming to reduce pollution from these micro-contaminants. Wastewater samples were analysed both at the inlet and outlet of wastewater treatment plants (WWTPs) in eastern Sicily to determine MPs concentration major and minor 10 μm in both inlet and outlet. The filter prototype was designed to be implemented at the outlet of WWTPs to retain MPs smaller than 10 μm, the most abundant but also the most harmful to human and environmental health. Toxicological studies were conducted to analyse the toxic effects of MPs on mussels before and after the use of the prototype filter, which aims to capture MPs particles before they can be released into the environment, showing reduced toxicity with use of the filter. The project is ambitious, and it enabled the development of a new technology to combat environmental pollution from MPs, a topic widely debated in recent years due to ongoing environmental degradation caused by human activities.File | Dimensione | Formato | |
