The gray color has invaded the sky in many parts of Andalusia, such as Seville. The origin of this unexpected cloudiness is on the other side of the pond, in the the fires that have been raging for weeks hectares of vegetation in Canada.
The suspended particles traveled some 7,000 kilometers through the jet stream until they reached the Iberian Peninsula, leaving those skies overcast and opaque. Now, does the soot layer negatively affect the air quality?
The experts of the National Meteorological Agency (Aemet) They pointed out that the phenomenon is not particularly rare and that the presence of Canadian soot particles in our atmosphere should not deteriorate air quality or harm people’s health as long as it persists.

Air pollution in Seville
Indeed, if we look at the air quality indexes in Sevillewe can verify that this Wednesday, June 28, it is at 56, average quality level, in the approximate values in which it is customary. For Thursday it should rise to 63, on Friday it would drop to 41, at the right level, to return to 56 on Saturday.
That is, the level of pollution fluctuates within the current parameters of the Sevillian capital despite the fact that suspended particles of dust, ash and soot It is higher this Wednesday (36) due to the smoke coming from Canada to go down in the following days until it remains below 20.
This does not mean that the air quality in Seville is optimal ―a report prepared by Environmentalists in action Together with data collected from seven official air quality measuring stations in the Andalusian capital, it shows that air quality “has deteriorated” in 2022―, but it shows that the Canadian soot cloud had no particular impact on it.
