A causa della situazione critica della qualità dell’aria a sud delle Alpi, anche sabato sono stati registrati superamenti del limite stabilito dall'Ordinanza contro l'inquinamento atmosferico, permane il limite di velocità di 80 chilometri orari su autostrade e semiautostrade a sud del ponte diga di Melide, compresa la Mendrisio-Gaggiolo.
Sabato pomeriggio, verso le 14.00, i valori delle polveri fini nel Sottoceneri rimanevano molto alti: 110 microgrammi al metro cubo a Mendrisio e 92 a Chiasso.
Aria poco pulita
Per far fronte alla situazione, le autorità cantonali hanno fissato a 20°C la temperatura negli stabili dell’amministrazione nel Mendrisiotto.
