Gallo Tre Re Mezzana Corti has had some high levels of air pollution, both in times past and continuing on well into 2021. Italy as a whole typically sees its cities come in amongst the top most polluted ones ranked in Europe, being a repeat offender with its lack of emissions standards and regulations, allowing many different polluting sources to go on unchecked. As such, the result is many of its cities coming in amongst not only Europe's most polluted cities, but within the whole worlds top 500 most polluted cities, as of 2020.
Gallo Tre Re Mezzana Corti itself presented with a US AQI reading of 53 in June of 2021, a reading that would classify the air quality at that particular time as being in the ‘moderate’ ratings bracket. This requires a US AQI reading of anywhere between 51 to 100 to be classified as such, and is color coded as yellow, as per the air quality maps and graphs present both on this page and throughout the IQAir website. Air quality readings such as this represent a pollution level whereby the general public may not experience any adverse or ill health effects; however certain sensitive or vulnerable individuals may have mild irritation, or respiratory related symptoms start to appear.
People who fall into the vulnerable group category, meaning that they would need to take extra precaution during spells of high pollution, would be ones such as young children and babies. During the vital formative years of a child's life, disruption to the nervous system or damage to the lungs can result in many issues, some of them being lifelong if the pollution exposure is not ceased.
Pregnant mothers are also particularly at risk as well, due to the prominent changes that can occur to the child being carried, with many chemical pollutants and even ultrafine particles having a salient effect on the health of the baby. This may result in instances of low birth weight, premature birth or even miscarriage. Furthermore, the resulting changes that can take place via pollution related damage can cause neurological and physical issues, with the affected babies being born with both physical and mental defects, in worse case scenarios.
Other vulnerable groups present in Gallo Tre Re Mezzana Corti would be ones such as the elderly (even more prominent in Italy due to its large portion of the population belonging to the senior citizen bracket), who can suffer from grave effects from even minor respiratory infections. Those with compromised immune systems, pre-existing health conditions, and hypersensitivity towards chemicals should also take extra care during periods of high air pollution.
To close on the question, Gallo Tre Re Mezzana Corti displayed some decent levels of air quality over the months of May and June of 2021, with its US AQI readings often coming in as ‘good’ rated, or on the lower end of the ‘moderate’ ratings bracket. However, when looking back at pollution levels as recorded in years past, one can quickly see that Gallo Tre Re Mezzana Corti is a city that sees periods of extremely clean air quality, followed by other months whereby the pollution level rises to dangerous heights, which will be discussed in further detail in the following questions.
Some of the main causes of polluted air that take place in Gallo Tre Re Mezzana Corti would be ones such as ambient emissions, coming from the many vehicles in use in Gallo Tre Re Mezzana Corti as well as surrounding areas. Due to having a more rural nature to it and its surrounding region, Gallo Tre Re Mezzana Corti would see more vehicles in use that are significantly more aged and past their best years, due to lack of stringent regulations regarding vehicle condition and the fumes they can give off.
This leads to larger amounts of fine particles and chemical pollutants being released into the atmosphere as a result of the poor combustion process, along with noxious oil vapors being leaked into the air. The surrounding region of Pavia has many industries taking place, and whilst they may not be enough to destroy the natural beauty of Gallo Tre Re Mezzana Corti and its neighboring cities, their resulting emissions from the various combustion processes that take place can lead to the massive spikes in PM2.5 that were seen on record.
The burning of fossil fuels such as coal, diesel and natural gas, along with novel emissions released as a byproduct of the industrial processes (such as burnt plastic fumes, heavy metals and other hazardous materials being leaked into the surrounding environment) has lead to the large PM2.5 readings on record in Gallo Tre Re Mezzana Corti, along with the burning of organic material such as firewood and charcoal in certain households.
Some of the main pollutants found in the air in Gallo Tre Re Mezzana Corti would be ones such as black carbon and volatile organic compounds (VOCs), both of which are formed from the poor or incomplete combustion of fossil fuels and organic material. As such both of these pollutants can find their release from cars, factories, power plants and even the open burning of organic waste.
Some examples of VOCs include chemicals such as benzene and formaldehyde, which can also be found emanating from certain household products (ones that contain strong glues or varnishes, or items such as low quality scented candles, with VOCs being one of the largest contributors to indoor pollution).
With the PM2.5 numbers on record over the year of 2020, it can be seen that the months of January, February, November and December were the most polluted. This is a common pattern in many European cities, with the first and last few months of the year often having the highest levels of PM2.5 on record.
Out of all of these months, January and November came in with the highest readings, presenting with 69.9 μg/m³ and 62.6 μg/m³ respectively, placing both of them into the unhealthy air quality ratings bracket, the only two months of the year to do so.
Whilst it has some months with very high levels of air pollution, Gallo Tre Re Mezzana Corti also has some extremely clean months on record. May through to August all came in with readings that sat within the world health organization's (WHO's) target goal of 10 μg/m³ or less, for the best and safest quality of air.
These readings were 7 μg/m³, 6.1 μg/m³, 4.5 μg/m³ and 9.3 μg/m³ respectively, making July the cleanest month of the year by a significant amount with its reading of 4.5 μg/m³. Of note is that from 2019 through to 2020, the yearly average of air pollution seemed to get considerably worse, with 2019’s average reading of 19.1 μg/m³ increasing up to 28.5 μg/m³ in 2020, placing Gallo Tre Re Mezzana Corti in 438th place out of all cities ranked worldwide for that year.
