La qualità dell’aria è notevolmente peggiorata nel Mendrisiotto da martedì scorso. Lo segnala il Dipartimento del territorio.
Nelle due stazioni di misura di Chiasso e Mendrisio il valore medio giornaliero di polveri fini presenti nell’aria registrato il 10 dicembre è stato di 86 nanogrammi nella cittadina di confine e 81 nel Magnifico borgo. Mercoledì 11 sono stati registrati 110 nanogrammi a Chiasso e 86 a Mendrisio.
Il limite previsto dall’Ordinanza contro l’inquinamento atmosferico è di 75 nanogrammi. Questi superamenti sono determinati da condizioni meteorologiche di alta pressione. Se la situazione dovesse perdurare, tornerebbe il limite degli 80 km/h in autostrada. Sarebbe una prima in dicembre.
Per i prossimi giorni – scrive il DT – rimarranno sostanzialmente le medesime per cui l’aria non sarà ricambiata. Le autorità raccomandano pertanto alla popolazione di prendere le abituali misure atte a diminuire le emissioni di PM10.
