Il Laboratorio cantonale del cantone Ticino ha monitorato anche quest'anno i contaminanti ambientali presenti nei pesci del Verbano. Per quanto riguarda i metalli pesanti, l’arsenico e il mercurio sono presenti in quantitativi significanti (ma non pericolosi per la salute del consumatore) nei pesci analizzati, confermando uno stato ecologico piuttosto critico delle acque del lago.
Un altro dato interessante è quello che riguarda il DDT presente negli animali: i limiti sono rientrati nella soglia di tolleranza dopo la scoperta fatta negli scorsi anni di questo inquinante nell'ecosistema lacustre.
Per le analisi sono stati catturati, durante il periodo primaverile del 2016, 10 agoni, e i risultati sono riferiti alla parte edibile ottenuta dopo la filettatura.

Le analisi del Laboratorio cantonale confermano i dati di uno studio dell'Ufficio federale dell'ambiente che ha interessato anche il Ticino. NouvoRSI l'ha presentato così
