I fiumi dell'Altopiano sono carichi di pesticidi, come dimostra uno studio realizzato dall'Istituto per la ricerca sulle acque dei Politecnici federali, commissionato dalla Confederazione e da cinque cantoni.
I risultati confermano quelli ottenuti già l'anno scorso dopo un'indagine che aveva preso in considerazione gli stessi torrenti, ossia Salmsacher Ach (SG), Furtbach (ZH), Surb (AG), Limpach (SO) e Menthue (VD).
Il dito è puntato contro insetticidi e fungicidi, responsabili della scomparsa di tanti piccoli invertebrati, la cui presenza è in genere sottovalutata.
