Minuscole particelle di plastica sono state rilevate nelle acque del Lago Maggiore e nel Ceresio. Si tratta di un tipo di inquinamento rilevato in tutti i maggiori laghi svizzeri e il cui effetto è ancora soggetto di ricerche.
Per combattere la presenza di microplastiche nei laghi ticinesi, il Consiglio di Stato ha deciso di potenziare i depuratori ma anche di attaccare il problema alla fonte, come il littering e lo smaltimento non corretto degli imballaggi, con una campagna di sensibilizzazione.
La prima giornata, ha annunciato il Dipartimento del territorio, si terrà martedì 26 febbraio ad Agno, con un evento aperto a tutta la popolazione che potrà seguire momenti informativi sulle microplastiche e la loro origine, oltre ad assistere alle operazioni di pulizia della riva e del fondale del lago.
