Air healthiness in Italy: Legambiente data

Air healthiness in Italy: Legambiente data
Air healthiness in Italy: Legambiente data

Turin 9 December 2021. L’air we breathe it is destined to have an important influence on our well-being, for this very reason very accurate analyzes are carried out in the different areas of Italy and the world.

Il Pm10: what it is and why it is dangerous

The main “enemy” corresponds to the Pm10, an atmospheric particulate matter that is released by urban traffic, domestic heating, industrial activities: in the latter case, however, PM10s also represent a pollutant at the level of indoor spaces, consequently companies are required to use special devices such as those proposed by Delfinvauums to avoid risks to the health of workers.

Without going too far into technical-scientific aspects, it is clear that PM10 rhymes with pollution and its danger is due to the fact that these particles, due to their tiny size, can be easily inhaled.

Unfortunately, the inhalation of PM10 represents a big risk to our health, and the correlation between the presence of these particles in the atmosphere and theonset of pathologies of the respiratory system, including tumors.

Air quality standards

In our country, a standard has been issued, precisely Legislative Decree n.155 of 2010, which substantially transposes Directive 2008/50 / EC on air quality.

This directive, being a Community law that binds member states to the achievement of a certain objective, established that in the various community territories the quantity of 50μg/m3 for more than 35 times within a year.

But is Italy managing to respect this limit? Although over the years the health emergency has certainly reduced urban traffic in certain periods of time, in many areas we are far from falling within this threshold.

In this regard, a very authoritative report is certainly the one produced by Legambiente and called “Mal’Aria di città”, which can be consulted in full at this link.

As can be seen, unfortunately, in many Italian cities overruns to the threshold of 50μg / m3 are very frequent, so it is clear that there is still a lot to do to significantly improve the healthiness of the air.

Overruns of the safety threshold: Turin the worst city, followed by Venice and Padua

The cities that turned out to be the most critical in terms of air quality turned out to be, in order, Turin, Venice and Padua.

A Torino, at the control unit located in Via Grassi, over the course of 2020 the aforementioned threshold was exceeded 98 times, a figure that is therefore far from the limit of 35 set at Community level.

A Venezia the situation is only slightly better, the control unit located in via Tagliamento has in fact recorded 88 annual exceedances, while a Padova the exceedances were 84 and were recorded by the control unit in via Arcella.

Following this ranking, Rovigo, Treviso and Milan appear in the order, however the presence of PM10 in the atmosphere is not an exclusive problem in the North, as confirmed by the fact that in seventh place there is the city of Avellino, which registered 78 annual exceedances.

Ranking also confirmed by the annual average values

The criticality of the cities mentioned is also confirmed by another ranking, namely that relating to average annual values.

From this point of view, the WHO guidelines indicate the threshold not to exceed the average of 20 μg/m3 on an annual basis, however a Torino this average stands at 35 μg / m3.

In second place in this ranking are, at the same level, the cities of Padua, Rovigo and Milan, which recorded an annual average of 34 μg / m3.

Compliance with Community thresholds is still a long way off

The data, unfortunately, are emblematic: although many Italian cities have recently carried out virtuous processes, improving air quality, in many areas of Italy it is unfortunately still far from being able to say that PM10 levels are not at worrying levels. , so there definitely is still a lot to work.
