In conclusion is that the air in Vic is good, except for the excess of ozone (o3) that exceeds the limits established by the European Union. Also that at the beginning of summer the level of ozone in the air increases and at the end of September it decreases.
This happens because the UV radiation from the sun breaks the o2 particles, these increase in summer due to air conditioning, apart from in summer there are more hours of sun, therefore greater exposure of the particles to it.
