The massacre caused by Covid-19 in the Northeast, especially in the first two waves of the pandemic, was facilitated by the high level of smog that afflicts the Po valley. Among the 29 most polluted cities in Italy, all in the North, in fact, there are the Lombard capitals (in the first places), six Venetian ones, namely Vicenza (twelfth), Venice (16th), Padua (17th), Verona (19th), Treviso (21st) and Rovigo (25th), and five Emilians . They are Modena, Parma, Reggio Emilia, Rimini and Bologna. In the middle of Genoa, Turin, Alessandria, Vercelli and Novara. Belluno is saved, 53rd square.

The differences

It emerges from the study published by the University of Pisa (author Gaetano Perone) on Nature, which completes the cycle of international research on the relationship between pandemic and smog. Unlike other scientific worksthe report does not examine part of Italy but all 107 provinces, it does not focus only on some pollutants but analyzes the nine most significant, including heavy metals (nitrogen dioxide, ozone, Pm10 and Pm25, benzene, benzoapyrene, arsenic, cadmium and nickel) and considers factors so far neglected. That is the demographic characteristics, the weather, the distance of the capitals from the borders and from the airports.

The results

Result: A concentration in the air of more than 10 micrograms per cubic meter of nitrogen dioxide, Pm2.5 and Pm10 associated respectively with an increase of 40.2, 63.7 and 81.6 deaths per 100 thousand inhabitants – writes Professor Perone -. The same concentration of the same pollutants associated with a growth of respectively 0.27%, 0.44% and 0.54% of infections. Poor air quality may have favored the transmissibility of Covid-19 and increased the risk of serious and fatal diseases. The reason was also clarified by previous studies: Air pollutants can cause irritation, inflammation and serious infections and diseases of the lungs and airways. And the annual emissions of Pm10, Pm2.5 have exceeded the limits set by the European Union and the WHO. But why the Sars-Cov2 is raging on Northern Italy? This result reflects the deep historical gap in the country’s industrialization and development, pushed further north – the report reads -. Industrial, commercial and agricultural activities, intensive livestock farming, animal husbandry, the production and distribution of energy, in addition to vehicle exhaust emissions and waste, are the main causes of pollution. And if Vicenza is the most at risk in Veneto, on the one hand due to the high concentration of smog linked to the concentration of tanneries and industries, on the other due to the greater number of immigrants. In fact, Perone writes: Foreigners have a greater propensity to return to their countries of origin, which could increase the likelihood of meeting infected people. For the same reason, the proximity of a city to an airport is a cause for alert.

Other factors of demand

Other risk factors are previous illnesses and obesity, concepts known as the greater propensity to become infected in men and that rain, facilitating interpersonal distances, hinders contagion. But there is a twist: Nicotine has a protective effect – closes the studio – the paradox of smokers less exposed to Covid than non-smokers appears. And speaking of Sars-Cov2, the new bivalent vaccines from Pfizer and Moderna are arriving in Veneto. Formulated on the virus originally from Wuhan but adapted to the Omicron 1 variant, for now they are intended for third and fourth doses, so they will be administered to the over 60s, to people from 12 years and up with frailty, to health workers, pregnant women, guests and employees of the RSA. From tomorrow it will be possible to book vaccination with the new bivalents using the platform or by contacting family doctors.
