Is the air in Ceglie Messapica badly polluted?

The air quality in Ceglie Messapica is amongst some of the worst in Europe, according to data collected over the course of 2020. The pollution levels continue to be somewhat erratic, even well into 2021, coming in with readings that range from extremely clean, all the way to levels that could be highly damaging, for both vulnerable or at-risk members of the population (who will be described in greater detail in short) as well as the general public or healthy young adults, all of whom can develop a number of health issues as a result.

Looking at its levels of US AQI as taken in late May of 2021, Ceglie Messapica displays some rapid turnarounds in its readings, with one hour to the next showing large differences. Using the air quality map (as available at the top of this page, as well as on the AirVisual app for hourly updates and air quality forecast readings), it was shown that Ceglie Messapica came in with a US AQI reading of just 1, placing it into the absolute lower end of the ‘good’ rating air quality, which requires a US AQI reading of anywhere between 0 to 50 to be classified as such.

US AQI itself is a number aggregated from several main air pollutants found within the atmosphere, not just within Ceglie Messapica, or Italy, but worldwide, being the main ones emitted from the most common pollution sources. These are pollutants such as sulfur dioxide (SO₂), as well as nitrogen dioxide (NO₂) and ozone (O₃). PM2.5 and PM10 also constitute the particulate matter collective used in the calculation of US AQI, with PM2.5 being the far more dangerous of the two, as well as being used as a prominent measure of air quality in its own right (typically used to display the yearly readings of a city or countries average pollution levels).

Whilst Ceglie Messapica came in with a highly clean reading of 1 on the US AQI scale (color coded as green, with each pollution ranking having its own number for classification, along with an accompanying color, for ease of navigation when referring to air quality maps or graphs), little more than an hour later, a reading of 57 was taken, showing a rapid spike up in the air pollution levels. This US AQI reading placed Ceglie Messapica into the ‘moderate’ pollution ratings bracket, which is color coded as yellow, and requires a reading of anywhere between 51 to 100. Whilst this is not overtly bad by any means, especially when compared to its months of higher pollution, sensitive individuals may wish to avoid outdoor strenuous activity, as some minor respiratory symptoms may start to present themselves.

Besides the US AQI reading, as mentioned, PM2.5 is often used to calculate the yearly averages, as well as months from years past. Over the course of 2020, Ceglie Messapica came in with a PM2.5 reading of 31.7 μg/m³ as its yearly average, placing it into the higher end of the ‘moderate’ pollution ratings bracket, which when going by the PM2.5 standard, requires a reading of anywhere between 12.1 to 35.4 μg/m³ to be classified as such. This placed Ceglie Messapica in 12^th place out of all cities ranked in Europe over 2020, as well as in 350^th place out of all cities ranked worldwide on the same year.

What are some health issues that may arise in Ceglie Messapica from breathing polluted air?

During bouts of high pollution (which be discussed in further detail in the last two questions below), many unpleasant or dangerous health issues may arise as a result of pollution exposure, particularly when it occurs over prolonged periods of time, or for vulnerable groups of people.

Epidemiological studies have shown that that exposure to PM2.5 and other chemical pollutants can lead to ailments such as chronic obstructive pulmonary disease (COPD), asthma, pneumonia and bronchitis (which actually fall under the COPD bracket, due to it encompassing many respiratory illnesses that result in obstructed airways and poor lung function), as well as more severe issues such as heart attacks, ischemic heart disease, strokes and even death. Cancer of the lungs and skin may also present itself, along with a number of other epidermal conditions such as acne, psoriasis and eczema.

Who is most vulnerable to air pollution in Ceglie Messapica?

Vulnerable groups of people amongst the population would include ones such as young children and babies, who are highly susceptible to developing both neurological and physical defects as a result of excessive pollution exposure, during their highly vital and formative years. Resulting changes to the nervous system can lead to stunted physical and mental growth, leading to a lower quality of life, as well as a number of health issues (such as asthma or skin conditions) that may become permanent if exposure is not halted.

Other groups include the elderly, who are also highly susceptible to possible terminal illnesses as a result of respiratory infections and other similar conditions. Pregnant women, those with pre-existing health conditions, as well as those with poor immune systems or a hypersensitivity towards chemicals or particles may also consider themselves part of the ‘vulnerable groups’ demographic.

At what time of the year is the air quality at its highest in Ceglie Messapica?

Observing the air quality data collected over 2020, it can be seen that the months of August and September showed massive spikes in their PM2.5 count, so large that it skewed the readings for the entire year and made the yearly average come in way higher than it could have if these elevations were averted.

August and September both presented with readings of 87.7 μg/m³ and 86.1 μg/m³ respectively, placing them into the ‘unhealthy’ ratings bracket, indicating a time in which the air would be permeated with clouds of hazardous particles, smoke, vehicle exhaust and haze.

Does Ceglie Messapica see any improvement in its air quality during certain months?

Despite the two months that saw huge rises in their PM2.5 count, other months of the year showed far more appreciable readings of air quality. The cleanest months on record throughout the year were February, May, June, July, October and November, showing that Ceglie Messapica had no clear cut period where the PM2.5 count was low for extended lengths of time.

Out of all of these months, June showed the best level of air quality, coming in with a reading of 10.7 μg/m³, placing it within the ‘good’ air quality ratings bracket, the only month of the year to do so in 2020.
