Cosa accomuna il lago Maggiore, il Ceresio, il Tahoe negli Stati Uniti e il Neagh in Gran Bretagna? Il livello di inquinamento di plastiche e microplastiche, per tutti e quattro troppo elevato. È la conclusione di uno studio internazionale pubblicato sulla rivista specializzata Nature.
La ricerca, condotta da Veronica Nava e Barbara Leoni dell’Università di Milano Bicocca, ha coinvolto 79 ricercatori provenienti da tutto il mondo e ha analizzato le acque di 38 laghi in 23 diversi paesi.
Stando allo studio, i laghi in aree densamente popolate sono particolarmente suscettibili alla contaminazione da plastica e contribuiscono in maniera non marginale all’inquinamento globale.
“La plastica che si accumula sulla superficie dei sistemi acquatici - spiega Veronica Nava - può favorire il rilascio di metano e di altri gas serra. Le materie plastiche possono arrivare oltre l'idrosfera e interagire con l'atmosfera, la biosfera e la litosfera, influenzando potenzialmente i cicli biogeochimici".
