Il 2024 si conferma un anno molto positivo per la qualità dell’aria in Ticino. Lo indica il rapporto pubblicato giovedì dal Dipartimento del territorio, secondo cui i valori registrati si avvicinano sensibilmente a quelli del 2023, finora l’anno migliore dall’inizio delle misurazioni.
Per il quinto anno consecutivo, i valori medi annui del diossido di azoto restano sotto i limiti in tutto il Cantone. L’ozono segna una netta riduzione delle ore di superamento e raggiunge livelli vicini ai minimi storici degli ultimi 25 anni. Anche le polveri fini proseguono la discesa, con nuovi record positivi; unico sforamento, lieve, alla stazione di Chiasso.
Il miglioramento è attribuito sia alla riduzione delle emissioni sia a condizioni meteorologiche favorevoli, in particolare un inverno caldo e un’estate ricca di precipitazioni.
Migliora la qualità dell'aria
