For days the weather in many Italian regions, especially in the Po Valley, has been perpetually and sadly foggy.
The most affected regions were those in northern Italy, particularly the plains of Piedmont, Lombardy, Veneto and Emilia Romagna, where air pollution levels have been steadily rising.
The upcoming cold snap will certainly be good for clearing the atmosphere of all fine and ultrafine particles, but we should not get too excited as this winter’s weather trend is towards high pressure and static climate. In other words, sooner or later things will change again and the smog levels will be very high again.
The interaction of fog and smog
Current weather conditions are conducive tothe formation of a dangerous mix of fog and air pollution,which not only has a negative impact on the environment, but also on human health.
The lack of ventilation facilitates the accumulation of particulate matter, such as particulate matter (PM10 and PM2.5), nitrogen oxides and other harmful substances, increasing smog levels, especially in urban and industrial areas. The Po Valley is one of the most vulnerable regions due to its special geographical nature: surrounded by mountain ranges such as the Alps and the Apennines, it is exposed to limited air exchange.
This contributes to the formation of a “cap” of pollution that lingers at low altitudes and exacerbates the air quality problem Dense fog, which is common at this time of year, further aggravates the situation as it traps pollutants and increases the concentration of harmful substances in the lower layers of the atmosphere.
The effects of air pollution
Air pollution caused by the current weather conditions can have serious health consequences, especially in the large cities of northern Italy and in industrial areas.
Prolonged exposure to high levels of smog is associated with an increased risk of respiratory diseases such as asthma and chronic bronchitis, as well as cardiovascular disease.
The most serious impacts occur among the most vulnerable populations: children, the elderly, and those with chronic illnesses are particularly at risk. Fine particles like PM2.5 enter the lungs and can enter the bloodstream, causing inflammation that worsens existing conditions.
Meteorology and health experts warn that the combination of air pollution and static weather conditions could prolong smog episodes until there is a significant change in atmospheric conditions, with the arrival of cooler and more unstable air currents.
How to protect yourself during foggy periods
Health authorities recommend taking some precautions to reduce exposure to the negative effects of air pollution.
For example, it is recommended to limit time outdoors during the midday hours, when smog levels tend to be highest.
Intense physical activity outdoors should be avoided, especially in the areas most affected by pollutant accumulations. It is particularly important to pay attention to the needs of children and the elderly, who are more vulnerable to the effects of fine dust Additionally, people living in areas with high smog levels may consider using air purification devices in their homes.
Besides that It is recommended to monitor daily weather forecasts and air quality in order to adapt their activities and movements, especially in urban and industrial areas of the Po Valley.
