TheEarth Day is celebrated today all over the world. According to Legambiente, from January to March 2024 there are already eight cities that have been outlawed for fine dust , having exceeded the PM10 limit of 35 days in a calendar year with an average of more than 50 micrograms per cubic metre (µg/mc).
Verona (Borgo Milano) with 44 days of exceedances in the first 91 days of the year, followed by Vicenza (San Felice) with 41, Padova (Arcella) 39, Frosinone (Scalo) 38, Brescia (Villaggio Sereno), Cremona (Piazza Cadorna), Torino (Grassi) and Venezia (Via Beccaria) with 36.
Cities on the Edge
.Instead, Treviso (Via Lancieri) is at the limit with 35 days of overruns, Modena (Giardini), Milan (Senato), Monza (Via Machiavelli), and Rovigo (Centro) 34. From now on, observes the environmental association, the outlawed cities can no longer exceed the limit, and the emergency will have to be dealt with systematically for the rest of the year (despite the fact that springtime makes the problem less acute and felt by administrations and citizens) to avoid that next autumn, with the change of season, these cities will seriously risk doubling the allowed overruns.
The plenary in Strasbourg
The air quality data were also released by Legambiente ahead of the last plenary session (22-25 April) in Strasbourg for the final approval of the revision of the European air quality directive.
For 69% of the stations at least one day with a concentration above 100 µg/mc
.The first months of the new year were characterised by peaks of fine dust, with daily averages well above the regulatory limits. Sixty-nine per cent of the monitoring stations analysed (109 out of a total of 168 for which data was available) had at least one day with a concentration above 100 µg/mc (against the daily legal limit of 50 µg/mc) up to a maximum recorded of over 200 µg/mc; an extremely high daily concentration that not only doubled the permitted limit (in 23 of the 109 stations it even tripled!), but above all was repeated on several occasions. For example, in Venice (Via Beccaria) there were 12 days with a concentration above 100 µg/mc; in Rimini (Flaminia), Milan (Senato), Padua (Mandria), Piacenza (Giordani Farnese) and Modena (Giardini) 8; Verona (Borgo Milano), Bologna (Porta S. Felice), Ravenna (Zalamella) and Ferrara (Isonzo) 7. If filtered with the threshold of 75 µg/mc (one and a half times the daily limit), the number of control units that have repeatedly exceeded this value for at least 10 days (out of a total of 91) is 27.
