Cianobatteri nel Lago Maggiore? Le fioriture rilevate a metà giugno, in particolare nella zona di Muralto, si sono dissolte. I controlli effettuati dal Laboratorio cantonale indicano un’evoluzione positiva della situazione.
Attualmente non risultano “problematiche particolari in altre spiagge del Lago Maggiore”. La situazione viene comunque costantemente monitorata.
Il Laboratorio cantonale raccomanda in ogni caso di verificare sempre lo stato dell’acqua prima di immergersi.

Cosa sono i cianobatteri?
I cianobatteri sono microrganismi utili e normalmente presenti in laghi e corsi d’acqua. La loro crescita, spiega il Laboratorio cantonale, è favorita da un alto contenuto di nutrienti nell’acqua, dall’alternanza tra tempo stabile e caldo e temporali che portano nuovi nutrienti nel lago, così come da acque calme. L’eccessivo sviluppo di alcuni tipi di cianobatteri può dare origine a fioriture superficiali ben visibili.
Alcune specie possono produrre composti tossici e il rischio per gli esseri umani e gli animali aumenta con l’aumentare della densità delle fioriture.
